MIDI MODE. The RX17 is fully compatible with MIDI (Musical Instrument Digital Interface)-the technology that allows rhythm programmers, synthesizers and sequence recorders to control each other by means of simple cable connections. This Mode lets you select how the RX17 can control or be controlled by other MIDI equipment, or even by a Tape Sync signal recorded on tape. HINTS AND TIPS. A chapter which you'll find useful once youre familiar with the operations of your RX17. This chapter provides you with performance notes and a variety of tips on how you can creatively use the full potential of your RX17. It will broaden your knowledge of the operations described in the MODE chapters. ERROR MESSAGES. If you see an error message on the LCD (Liquid Crystal Display) of your RX17, refer to this chapter. Youll find out whether an operation has been executed incorrectly, or whether there is a technical malfunction. The SPECIFICATIONS and BLOCK DIAGRAM are followed by the MIDI IMPLEMENTATION CHART, for musicians who need specific information about the MIDI technology utilized in the RX17. You can, however, fully operate the RX17 with little or no technical know-how. The PATTERN CHART and SONG CHART enable you to keep an accurate written record of the rhythm programs you have created on your RX17. Photocopy these charts to provide enough for all your Patterns and Songs. The QUICK GUIDE is a reference index which lets you easily locate any particular operation on the RX17 useful in those moments when youre in a hurry and cant remember where in this manual an operation is described. And now-its all up to you. Enjoy your Yamaha RX17 Digital Rhythm Programmer!

You can change all instruments, or individual instruments, between the UPPER and LOWER instruments. NOTE 1: Instrument Change operations can be carried out at any time except during a cassette operation or MIDI Bulk Dump (operations 5.6 and 5.7). NOTE 2: The Instrument Change operation will NOT change instruments already programmed in a Pattern or Song. The following pairs of instruments can NOT be played together, because they reproduce the sound of two different ways of playing the same instrument. CONGA Hm / CONGA Ho CUICA H / CUICA L SD / RIM SHOT HH OPEN / HH CLOSED This also applies when writing Patterns. For example, if in the Step Write mode you enter a SD note, then enter a RIM SHOT note on the same beat, the SD note will be erased.
1.2 PLAYING THE RX17 INSTRUMENTS
The RX17 instruments can be played by tapping on the black instrument keys. While playing, adjust the MASTER VOLUME slider until you can hear the RX17s instruments at a comfortable listening level. The sounds you will hear will normally correspond to the instrument names written on the UPPER part of the instrument keys. You can easily change instruments on the RX17, as described in the next section.
1.3.1 ALL INSTRUMENT CHANGE

1. Press INST CHANGE

1.3 INSTRUMENT CHANGE
Each key on the RX17 features 2 instrument sounds. These are listed in the following chart. The RX17 has a total of 26 highly realistic voices, providing powerful drum sounds plus exciting Latin percussion sounds.

then return to the display shown before pressing INST CHANGE.
1.3.2 SINGLE lNSTRUMENT CHANGE

1.4.1 CLICK LEVEL

1. Press LEVEL
2. Press the key corresponding to the instrument you wish to change.
2. Use the 1 NO key to reduce the Click level, or the +1 YES key to increase the Click level. RANGE: 0 (OFF)31. 3. Press LEVEL again to return to the mode the RX17 was in before the Click Level operation.

1.4.2 INSTRUMENT LEVEL

3. Press the same instrument key again to change the instrument. 1. Press LEVEL
4. Press INST CHANGE again to return to the mode the RX17 was in before the Instrument Change operation.
2. Press the instrument key corresponding to the instrument whose level you wish to change.

1.4 LEVEL

The MASTER VOLUME slider controls the overall level of the RX17. There are, however, three other level operations possible.
CLICK LEVEL lets you change the level of the click signal that you will hear as a timing guide when writing a Pattern in Real Time. INSTRUMENT LEVEL lets you change the level of individual instruments. ACCENT LEVEL lets you change the Accent level of individual instruments (refer to section 1.5 for an explanation of Accents).
3. Use the 1 NO or +1 YES key to change the Instrument level. RANGE: 0 (OFF) 31. 4. Press LEVEL again to return to the mode the RX17 was in before the Instrument Level operation.
NOTE 1: These operations can be carried out at any time except during a cassette operation or MIDI Bulk (operations 5.6 and 5.7). NOTE 2: The 1 NO and +1 YES keys are used for level change, as well as many other operations. Pressing and releasing these keys causes a change of one unit. Holding them down causes a rapid and continuous change.

1.4.3 ACCENT LEVEL

2. Press and hold the green ACCENT key and then press the instrument key corresponding to the instrument whose Accent level you wish to change.

1.6.1 INSTRUMENT PAN

1. Press PAN
3. Use the 1 NO or +1 YES key to change the Accent level. RANGE: 31. 4. Press LEVEL again to return to the mode the RX17 was in before the Accent Level operation. NOTE: If you have set a plus Accent level and an exclamation mark appears on the LCD (as in the above example) it means that the combined Accent level plus Instrument level is above 31 (the maximum possible Instrument Level). In this case, the Accent will not have as much effect as you intended. For example, if the level of a voice is 24, the maximum possible Accent level is 31 minus 24 = 7, so an Accent level of, say +10 is impossible. If you have set a minus Accent level and the exclamation mark appears, it means that the combined Accent Level plus Instrument level is zero or less, and the voice will not sound when accented.
2. Press the instrument key corresponding to the instrument that is to have its Pan position set. On the LCD the cursor will flash at the current pan position.
3. Use the 1 NO or +1 YES key to change the Pan position. The cursor will move to the new position. 4. Press PAN again to return to the mode the RX17 was in before the Pan operation.

1.5 ACCENTS

Pressing any instrument key while holding the green ACCENT key causes that instrument to sound at its accented level. This applies whether the RX17 is being played in real time, or programmed in either the Real Time Write or Step Write Modes. Accents allow you to add natural dynamics to your drum patterns. You can even enter negative Accent values, which will reduce the level of the instrument. See 1.4.3 ACCENT LEVEL.

1.7 TEMPO

The playback and writing speed of Patterns and the playback speed of Songs can be varied at any time by moving the TEMPO slider. You can also display the Tempo on the LCD, for precise Tempo setting. NOTE: This operation can be carried out at any time except during a cassette operation, during Initial Tempo setting (operation 3.2.7) or during MIDI Bulk (operations 5.6 and 5.7).

1.6 PAN

If you are using both the RX17s stereo outputs, you will find that the instruments are heard at different positions in the stereo sound image. You can easily alter the stereo position of individual instruments. NOTE 1: This operation can be carried out at any time except during a cassette operation or MIDI Bulk (operations 5.6 and 5.7). NOTE 2: 15 Pan positions are possible, from Left to Right. These correspond to positions 1/15 thru 15/1 on an RX15 Digital Rhythm programmer.

1.7.1 TEMPO

1. Press TEMPO
2. Use the 1 NO or +1 YES key, or the TEMPO slider, to change the Tempo. RANGE: 40250 quarter-notes per minute. NOTE: The TEMPO slider allows you to change the tempo in increments of 3 units in the range 40166, and in increments of 4 units in the range 166250. The 1 NO and +1 YES keys should be used for exact tempo setting. 3. Press TEMPO again to return to the mode the RX17 was in before the Tempo operation.
On the RX17, a Pattern means a one bar sequence, which repeats when you play it back. You write (enter) each note of a Pattern, by pressing the instrument keys. Pattern Writing can be done in two ways: Real Time (see 2.2) or Step Write (see 2.3). The Quantize feature allows you to set the fineness of Pattern Writing, i.e., the shortest notes that may be written (see 6.2.2. and 6.2.3 for a full explanation of Quantize). The RX17 lets you create up to 100 Patterns, numbered 00 thru 99.
You will see a w in the right upper corner of the LCD if the Pattern already contains data (w stands for written). This makes it easy for you to select an empty Pattern, should you wish to write a new Pattern. In the Pattern Select Mode, there are two methods of selecting Patterns. 1 NO and +1 YES keys This is a convenient way of selecting an adjacent or nearby Pattern. Pressing the 1/NO key selects the Pattern number immediately BELOW the current Pattern number. Pressing the +1/YES key selects the Pattern number immediately ABOVE the current Pattern number. Each of these keys when held down causes a continuous and rapid Pattern number change. NUMERIC KEY PAD This is a more convenient way of selecting a Pattern in a distant number range. Use the Numeric Key Pad to enter a two-digit Pattern number. Pattern numbers below 10 must be preceded by a zero. For example, for Pattern 5, enter 0 then 5. NOTE: The RX17 contains a variety of factory-preset Patterns in Pattern locations 50 thru 99. We suggest that you listen to all of themyou will find many of them immediately usable, while others can be edited to create your own Patterns. These Patterns are listed and fully described in the accompanying RX17 PATTERN BOOK. See 2.1.2 LOADING THE PRESET PATTERNS for a description of how to recall the preset Patterns.

2.3.5 STEPPING THROUGH A PATTERN
During Step Write, you can step through a Pattern forwards or backwards by using +1 YES or 1 NO respectively. As you pass each beat you will hear the instrument(s) entered at that beat. You can also step through rapidly by holding down either key. When you reach the end of a Pattern, an > End <" message will flash on the LCD. When you return to the beginning of a Pattern, a > Top < message will flash on the LCD.
This display shows 4 quarter-notes to the bar, indicated by the vertical pairs of small dots. The Quantize indicates 16 beats to the bar, each beat indicated by a horizontal dash. The flashing cursor prompts you to input a note or rest on the first beat of bar 1. You can now choose either of the following options (2A or 2B):
NOTE: The 1 NO key, does NOT enter any data. It is ONLY for stepping backwards through the Pattern.
You can edit (alter) the Accent Level of the note at which the cursor is flashing. This in effect allows you alter the level of each note, to add expressive dynamics to your Patterns. Hold down ACCENT and use +1 YES or 1 NO to raise or lower the Accent Level respectively. RANGE: 31. See 1.5 ACCENTS for a note about Accent Level limits.

2.3.6 DELETING NOTES

Notes can be deleted (erased) by stepping through a Dot Display until you locate the erroneous note, then holding the BEAT CLEAR key, and tapping the appropriate instrument key. The Note Marker will disappear, and the cursor will move to the next beat.
2.3.7 DELETING INSTRUMENTS
Entire instrument parts can be deleted (erased) from a Pattern, as follows. 1. From a Dot Display, press JOB Then use Function 3. to move the cursor to 3, to select
2.3.9 DOT DISPLAYS FOR LONG PATTERNS
The Dot Display only accomodates 16 beats. Your Pattern may have more beats than this, depending on its Length, and on the Quantize setting. For example a 6/4 bar (Length: 24/16) with a Quantize setting of 1/24 will contain 36 beats. In this case, when the cursor reaches the limit of the displayed portion of the Dot Display (going in either direction) the Dot Display will start to scroll (move across the LCD) so that succeeding portions of the Dot Display will appear, one beat at a time.
2.3.10 DOT DISPLAYS: THE X MARKER
2. Press the instrument key corresponding to the instrument you wish to delete. Its name will appear on the LCD. 3. Press +1 YES to continue this operation. (Or press START to return to the Dot Display, if you do NOT wish to delete the instrument). When X Markers appear on a Dot Display, they indicate notes that were entered at a different Quantize setting than the current Quantize setting. In other words, these notes fall in between the beats on the Dot Display.

2. The cursor will be flashing at the Volume Change value. Use the Numeric Key Pad to set this value. RANGE: 031. NOTE: The Volume Change function can NOT alter the volume of any note beyond the RX17s Instrument Level range (031). 3. The Volume Change is now set, and you can press +1 YES to move on to the next Part and continue editing, or press SONG or STOP/CONTINUE to exit Edit Song. Volume Changes are often entered AFTER all the Pattern numbers have been entered for a Song. See 3.2.10 INSERT PART for how to insert data into a Song. Remember that a Volume Change will create a new Part, and move all subsequent parts forward. 1. After selecting a Song and entering Edit Song, press JOB.

2. Use the

key (or hold JOB and press 2) to move the cursor to 2.
3.2.6 JOB 1: INITIAL TEMPO
This function lets you set the exact playback tempo for a Song that you have already edited. This lets you avoid the need for manually changing tempos between playback of Songs. Of course, any Tempo Change commands you have included in the Song will function (within the limits of the RX17s tempo range) and you can also vary the Tempo manually at any time. 1. After selecting a Song and entering Edit Song, press JOB.
3. Use the Numeric Key Pad to enter a three-digit Part number (RANGE: 001999). Then press +1 YES. The LCD will immediately show the selected Part, and the Pattern or other data contained there. Example: Part 006; Pattern 23.
You can now continue editing from this point.

3.2.8 JOB 3: COPY PART

2. You can now use the -1 NO and +1 YES keys to turn the Initial Tempo function Off or On respectively.
3. To set the Initial Tempo value, press TEMPO This function lets you choose a Part or group of Parts, and copy them to another location in a Song, or to the end of the Song. This saves time if you have programmed the Parts for a verse, and want to repeat the same verse later in a Song. You can copy the entire verse in one operation, instead of having to copy each individual Part. For example, suppose in this short 5-Part Song, you want to copy Parts 2 and 3 onto the end of the Song. BEFORE COPYING 4. Asterisks indicate that the Initial Tempo has not yet been set. If it has been set, the setting will appear on the LCD. Use the 1 NO and +1 YES keys, or the TEMPO slider, to set the Initial Tempo. 5. Press START to return to Edit Song (if you wish to continue editing the Song) or press SONG or STOP/CONTINUE to exit Edit Song.

3.2.7 JOB 2: SEARCH PART

This function lets you instantly locate any Part in a Song. This is useful and time-saving as it allows you to locate any point in the Song for editing (this can be compared to tape transport memory devices in recording studios, which allow you to punch in at a preselected point in a recording).

You can now, if you wish, cancel this operation and return to the Edit Song display, by pressing START. 2. Use the Numeric Key Pad to select the number of the Part you wish to insert, then press +1 YES. For example, Part 003.
3.2.10 JOB 5: INSERT PART
The lnsert Function does the opposite of the Delete Functionit lets you select any point in a Song that has already been assembled, and insert new Parts between the already-programmed Parts. For example, if you want to insert a Part between Parts 2 and 3 of a Song, this means that you have to insert a new Part 3. BEFORE INSERTING
3. You can now enter any data in the new Part 003, in the normal way by moving the brackets to the desired type of data, and entering the data value. For example. Pattern 99.
4. The new Part is now entered. You can now continue editing or press SONG or STOP/ CONTINUE to exit Edit Song.

3.3 CLEAR SONG

You can instantly clear (erase) a whole Song. This would be done, for example, if the RX17s Song memory were full and you wanted to write another Song. 1. After selecting the Song you wish to clear, select Function 3. AFTER INSERTING
At this point, you can press SONG to return to the Select Song display, if you do NOT wish to clear the Song. 2. Press +1 YES to continue this operation. You can also insert Repeats, Tempo Changes and Volume Changes.
You now have a second chance to cancel this operation, and return to the Select Song display by pressing 1 NO. 3. Press +1 YES to clear the selected Song. The LCD will show
then return to the Select Song display.

3.5 COPY SONG

The Song Copy function lets you copy any selected Song to another destination in the RX17s Song memory. This is useful if you want to copy a Song in order to alter it to create a new Song, while retaining the original Song.
1. After selecting the Song you wish to copy, select Function 5.

3.4 CLEAR ALL SONGS

You can instantly clear (erase) all 10 Songs. This would be done, for example, if the RX17s Song memory were full and you wanted to write more Songs. Use operation 4.1 to save the Songs on tape before clearing all Songs, if you wish to preserve the Songs for later use. You can also save Songs via MIDI, by using a MIDI data storage device such as the Yamaha MDF-1 MIDI Data Filer (see operation 5.7). 1. Press SONG and select Function 4. 2. Use the Numeric Key Pad to enter the number of the Song destination to which the selected Song will be copied.
At this point, you can press SONG to return to the Select Song display, if you do NOT wish to clear all Songs. 2. Press +1 YES to continue this operation. You can now cancel this operation by pressing 1 NO, if you do not wish to copy to the selected destination (for example, if it already contains data). The LCD will return to the Select Song display. 4. To copy the Song, press +1 YES. The LCD will show

The Function numbers (1 thru 3) allow you to select the Cassette Modes three Functions. This is done by using the o r keys to move the cursor to the appropriate Function number. The LCD will then display the selected Function. You can also move the cursor by pressing JOB plus the Numeric Key corresponding to the Function number. If you press only JOB, the cursor will move to Function 1. To exit the Cassette Mode, press any other Mode key. Cassette Mode Functions are numbered 4.1 thru 4.3 in this chapter.
It takes about one minute to save an average set of Pattern and Song data. After saving, the LCD will show
then return to the Cassette Function Select display. 3. Stop the cassette recorder. You should now execute operation 4.3 (Verify) to be sure that the data has been correctly saved.

4.2 LOAD

This Function allows you to load a complete set of Pattern and Song data from cassette into the RX17s internal memory. NOTE: When you load data into the RX17, ALL Patterns and Songs in the internal memory will be erased. Be sure that you do not need this data, before you load the new data. If you need the data in the internal memory, save it to another cassette before loading new data. 1. Press CAS then select Function 2.

4.3 VERIFY

This Function allows you to check that the data has been correctly saved onto tape, by comparing the data saved on tape with the data in the RX17s internal memory. It should be executed immediately after saving data. 1. Press CAS then select Function 3.
2. Make sure that the cassette containing the data is loaded into the cassette recorder, and is cued to playback from the beginning of the data you wish to verify. Press +1 YES.
2. Make sure that the cassette containing the data is loaded into the cassette recorder, and is cued to playback from the beginning of the data you wish to load. Also make sure that the playback level is high. Press +1 YES.
3. Start the cassette recorder running in the play mode. It takes about one minute to verify an average set of Pattern and Song data. After verifying, and provided the data has been correctly saved, the LCD will show
3. Start the cassette recorder running in the play mode. It takes about one minute to load an average set of Pattern and Song data. After loading, the LCD will show

2. To set the Sync, press +1 YES to select MIDI, or 1 NO to select INTERNAL. The LCD will show the selected Sync Mode.

5.2 MIDI CHANNEL MESSAGE

This function must be turned ON to allow the RX17 to receive or transmit MIDI Note data (see 6.5.3 MIDI NOTE RECEIVE and 6.5.4 MIDI NOTE TRANSMIT). 1. Press MIDI then select Function 2.
The Function numbers allow you to select the MIDI Modes eight Functions. This is done by using the o r keys to move the cursor to the appropriate Function number. The LCD will then display the selected Function. You can also move the cursor by holding JOB and pressing the Numeric Key corresponding to the Function number. If you press only JOB, the cursor will move to Function 1. To exit the MIDI Mode, press any other Mode key.
2. Press +1 YES to turn the Channel Message Function ON, or 1 NO to turn the Channel Message Function OFF.

5.3 SET RECEIVE CHANNEL

MIDI signals can be sent and received on any of 16 MIDI Channels. This Function allows you to select which MIDI Channel the RX17 will use for reception of MIDI signals when it is being played by an external MIDI keyboard, sequencer or music computer. 1. Press MIDI then select Function 3. 4. Press +1 YES to enter the MIDI Transmit Channel for all instruments. The LCD will show
then return to the display for MIDI Function 1. 2. Use the 1 NO and +1 YES keys to set the MIDI Channel number. RANGE: 01 16. 5. To set the MIDI Transmit Channel for individual instruments, execute Steps 1 and 2 of this Function, then press the instrument key corresponding to the instrument that is to be assigned. For example, Bass Drum.
5.4 TRANSMIT CHANNEL ASSIGN
This Function allows you to assign each of the RX17s 26 instruments to any one of the sixteen MIDI Channels, so that instruments can play one or more external MIDI devices. See 6.5.4 MIDI NOTE TRANSMIT for an application of this Function. All 26 instruments can be assigned simultaneously, or you can assign instruments individually by omitting steps 3 and 4 of this operation. 1. Press MIDI then select Function 4. 6.Use the +1 YES or 1 NO key to alter the displayed MIDI Transmit Channel number to the desired number. 7. You can now select another instrument, and assign it to a MIDI Transmit Channel. You can also use the Instrument Change Function (see operation 1.3) to change instruments, then return to this Function and assign them.
2. Press +1 YES to continue this Function.

5.5 MlDl NOTE ASSIGN

This Function allows you to assign each instrument to a MIDI note, so that the RX17s instruments can play or be played by an external MIDI device. The available range is over five octaves-large enough for the entire range of most MIDI keyboards. See 6.5.3 MIDI NOTE RECEIVE, and 6.5.4 MIDI NOTE TRANSMIT for applications of this Function. 1. Press MIDI then select Function 5.

The higher Quantize settings (1/24, 1/32, 1/48) allow you to enter more subtle or complex parts. If the Quantize is set to 1/48, the RX17 will be recording your music in increments of 1/48th notes, which are short enough to capture all the timing subtleties of your original performance.
6.5 MlDI OPERATIONS 6.5.1 MIDI CLOCK IN
A MIDI clock is what controls the rate that MIDI events occur. In other words, the tempo of the RX17. This is usually controlled by the RX17s internal clock. You can also use the clock of an external MIDI device to control the RX17. This enables you to keep the RX17s rhythms in synchronization with another rhythm programmer, or with digital music that is being played on a sequencer or music computer.
6.3 SONG OPERATIONS 6.3.1 LONG ACCELERANDO/RITARDANDO
The maximum duration of a Tempo Change is 99 quarter-notes, so if you want a longer Tempo Change, youll need to enter more than one Tempo Change. For example, if you wanted a gradual accelerando from 100 to 150 over a period of 32 bars of 4/4 (128 quarter notes) you could enter two Tempo changes: the first one with a Tempo Change Value of 25 and a duration of 64 quarter notes; and a second identical one 16 bars later. A convenient method is to enter a Tempo Change during a repeat section. The Tempo Change will also be repeated, allowing you to make a gradual Tempo Change over a long period (keep in mind that the Tempo range of the RX17 is 40250 quarter-notes/ minute).
APPLICATION EXAMPLE: RX17 plus QX21 plus TX81Z When you start play on the RX17, the QX21 will also start play. The RX17 will continuously send MIDI Clock signals to the QX21, to keep both units in perfect synchronization. If you change the Tempo on the RX17, the QX21 will also change tempo. The QX21 will automatically stop playing when the RX17s Song ends, or when you press STOP/ CONTINUE on the RX17.

6.5.3 MIDI NOTE RECEIVE

For this MIDI application use 5.1 SYNC to set the RX17s sync mode to MIDI. Also, use 5.8 ECHO BACK to turn ON the Echo Back feature, so as to allow the QX21s MIDI signals to be passed to the TX81Z via the RX17's MIDI OUT connector, which will be acting as a MIDI THRU terminal. In this example, the RX17 is controlled by a QX21 Digital Sequence Recorder, which is also controlling a TX81Z Multi-Timbral FM Tone Generator (which provides 160 state-ofthe-art FM voices featuring simulated Reverb, variable waveform operators and variable intonation). Digital music data is recorded into the QX21. When you start play on the QX21, the RX17 will also start play (either Pattern Play, or Song Play, according to whether you have selected a Pattern or Song on the RX17). The Pattern or Song will have been programmed to fit the music stored in the QX21. The RX17 will continuously receive MIDI Clock signals from the QX21, to keep both units in perfect synchronization. If you change the Tempo on the QX21, the RX17 will also change tempo. The RX17 will automatically stop playing when the music ends, or when you press STOP/CONTINUE on the QX21. Each of the RX17s 26 instruments can be assigned to a different MIDI Key. You can then play each instrument from a MIDI keyboard, sequencer or music computer. For example, if you set the RX17s Cowbell to C3 (Middle C), whenever you play Middle C on a DX21, or send Middle C data from a sequencer or music computer, youll hear the RX17s Cowbell. APPLICATION EXAMPLE #1: RX17 plus DX21

Sometimes you may see an unusual message on the RX17's LCD, indicating that an operation has been executed wrongly, or there is a technical malfunction. This chart lists those messages, their causes and remedies.
MESSAGE CAUSE A malfunction in the RX17 has caused all parameters (voice level, accent level, pan, MIDI settings) to be initialized. A malfunction in the RX17 has caused all Pattern and Song data to be cleared. During MIDI Bulk Receive, incorrect data was sent due to faulty cable or electrical interference. There is a checksum error in sequence data that you have tried to load from cassette, due to a fault in transmission. The RX17 contains different data to the data saved on cassette. During Bulk Receive, you are sending data to the RX17 that is not formatted for the RX17. During Bulk Receive or Cassette Load, you have cleared all data in the RX17 by attempting to load the wrong type of data. Too large amounts of MIDI data are being sent to the RX17 too rapidly. The RX17s Pattern or Song Memory is full, and further data cannot be entered. You have exceeded the maximum size of a Pattern, and further data cannot be entered. You have entered data in the Copy Part function which would result in a Song containing more than 999 Parts. 1. You have entered Part numbers in the Copy Part function where the second Part number is smaller than the first. 2. You have entered Part numbers in the Copy Part function which include the destination Part number. You have entered a Part number in the Copy Part function which is higher than the total number of Parts in the Song. You have tried to change the length of a Pattern that already contains data. The lithium battery, for memory backup, is running at less than 2.2 V. The lithium battery, for memory backup, is running at less than 1.5 V. 1. In the Copy Part function, you have entered a copy destination Part number that is higher than the total number of Parts in the Song. 2. In the search Part function, you have entered a Part number that is higher than the total number of Parts on the Song. REMEDY

Use operation 2.1.2 to load the Preset Patterns and Songs, or operation 4.2 to load Patterns and Songs saved on cassette. Check that the MIDI cable is not faulty. Also, read the PRECAUTIONS section of this manual for advice on electrical interference. Repeat the Load operation, making sure that the tape playback level is high. Also, check that the cassette cable is functioning correctly. If necessary, clean and demagnetize the tape heads. Make sure that the cassette you are using contains data that was just saved. If there is still a problem, save the data again and, execute the Verify operation once more. Make sure that the MIDI device connected to the RX17 is transmitting the correct type of data (i.e. RX17 Pattern, Song and Instrument data). Make sure that the type of data you are loading is correct for the RX17, then execute the load operation again. Press any key to clear the LCD. Send less dense data; or send data at a slower tempo.
