To connect a sustain pedal, see Using a Sustain Pedal on Page 26. tom of the keyboard, pull up the cover to remove it. 2. Place the batteries in the compartment as indicated by the polarity symbols (+ and ) marked below the compartment. 3. Replace the cover. When the keyboard stops operating properly, replace the batteries. Warning: Dispose of old batteries promptly and properly. Do not burn or bury them. Caution: If you do not plan to use the keyboard with batteries for a week or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

CONNECTING POWER

You can power your keyboard using internal batteries or with standard AC power using an optional AC adapter Notes: Connecting an AC or DC adapter automatically disconnects any internal batteries. Always disconnect the AC or DC adapter when you finish using the keyboard.

Using Batteries

Your keyboard can use six D batteries (not supplied) for power. For the best performance and longest life, we recommend RadioShack alkaline batteries. Cautions: Use only fresh batteries of the required size and recommended type. Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities. Follow these steps to install batteries. 1. While pressing the tabs on the battery compartment cover on the bot6

USING THE PRESET TONES

Your keyboard can sound like 200 different musical instruments or sound effects. The name and three-digit number for each preset tone is listed on the 200 TONES list on the keyboards top panel. Notes: The keyboard has 24-note (maximum) polyphonic sound. This means that you can play up to 24 different notes at the same time with most of the keyboards preset tones. Some of the keyboards preset tones, however, are capable of only 12-note polyphony. Most tones on this keyboard have been recorded and processed using a technique called digital sampling. To ensure a high level of tonal quality, samples are taken in the low, mid, and high ranges and are then combined to sound amazingly close to the originals. You might notice very slight differences in volume or sound quality for some tones when you play them at different positions on the keyboard. This is an unavoidable result of multiple sampling and is not a malfunction.
Cancelling Auto Power Off
To have the keyboard not automatically turn off during a session, turn on the keyboard while holding down TONE. The next time you turn the keyboard off then back on again, it will automatically turn off after about 6 minutes.
PLAYING THE DEMONSTRATION TUNES
To showcase its sounds, your keyboard can play two preprogrammed demonstration tunes. To start the demonstration, press DEMO. The keyboard plays the first demonstration tune (No. 0). To select the other tune, press or + on the keypad. The selected tunes number appears and the tune plays. The demo tune number and Demo appear at the top of the display. The mid-

Operation

Follow these steps to select and play a preset tone. 1. Press TONE. TONE and the current tones number appear. Note: The first time you turn the keyboard on, it automatically selects the tone GRAND PIANO (No. 000). 2. To play a different tone, choose a preset tone from the 200 TONES list and enter its three-digit number on the keypad. As you press the keys, the selected digits appear. Notes: You can select the next highest or lowest numbered tone by simply pressing + or on the keypad. The names of tone numbers are marked to the right of the keyboards display. The names for tone numbers 128167 appear in the table below. Memory locations are reserved for custom tones that you create (see Using the Custom Tone Synthesizer on Page 20).

Using VARIATION

Each of the keyboards 100 preset autorhythms has a built-in variation (alternate) to its normal beat pattern. The variation differs slightly from the normal rhythm, so it is almost like having two rhythms in one! To play the alternate rhythm, press VARIATION/FILL-IN. The variation plays continuously at the selected tempo. To insert the fill-in segment in the alternate rhythm, press VARIATION/FILL-IN. The keyboard adds a 1- to 2-measure variation in the rhythm. To return to the normal rhythm, press NORMAL/FILL-IN. To stop the auto-rhythm, press START/ STOP.

Using SYNCHRO

This feature lets you synchronize the start of an auto-rhythm with the beginning of your music. After you select and enter an autorhythm, press SYNCHRO/ENDING, then begin playing the keyboard. The keyboard automatically begins to play the rhythm when you press any key within the first 11/2 octaves of the lower end of the keyboard (the first 18 keys from the left side of the keyboard).

Using INTRO

This feature lets you start the selected auto-rhythm with a light, 3- to 8-measure introduction that blends easily into the selected rhythm. To start a rhythm with an introduction, select and enter the rhythm, then press

Using ENDING

To end the selected rhythm with a special 3- to 8-measure flourish, press SYNCHRO/ENDING while the auto-rhythm is
playing, about 38 measures before you want the rhythm to end. The keyboard plays a special ending, then automatically stops the rhythm.

accompaniment. After you press the auto accompaniment keys while using concert chord or standard fingering, the keyboard plays the same chord until you press other accompaniment keys to play a different chord or press START/STOP.

USING AUTO ACCOMPANIMENT

The 18 keys on the left side of the keyboard with note labels above them are called accompaniment keys.
Accompaniment Keyboard Melody Keyboard
Adjusting the Accompaniment Volume
The keyboard lets you adjust the volume of your accompaniment separately from the overall volume of the keyboard. 1. Press ACCOMP VOLUME. The current accompaniment volume setting appears. 2. Within 5 seconds, enter a number from 0 (softest) to 7 (loudest) on the keypad. The numbers appear as you press the keys. Or, press ACCOMP VOLUME then repeatedly press or + to select the next lowest or highest accompaniment volume setting. To reset the accompaniment volume to its default value of 87, press ACCOMP VOLUME then press and + at the same time. Note: The auto-accompaniment patterns consist of four parts: chord 1, chord 2, bass, and rhythm. You can delete any of the parts by using the mixer function. See Using the Mixer on Page 18.

You can set the keyboard to play three different types of auto accompaniment using the accompaniment keys. Concert Chord lets you play chords on the accompaniment keys using chord formations of from one to four notes. The number of keys you press determines the type of chord that plays (see Concert Chord on Page 16). Standard Fingering lets you play chords on the accompaniment keys using standard chord formations of three or four notes (see Standard Fingering on Page 16). Full-Range Chord lets you play the melody using the entire keyboard while the keyboard plays accompaniment based on your auto-rhythm selection. Notes: You can use the keyboards rhythm controls (INTRO, NORMAL/FILL-IN, VARIATION/FILL-IN, and SYNCHRO/

Concert Chord

The concert chord method lets beginning keyboard players easily select and play a chord. The number of accompaniment keys you press determines the type of chord that plays. This chart shows the chord type that plays when you press one, two, three, or four accompaniment keys at the same time.

The bar at the bottom of the level meter disappears.
Notes: Normally, keyboard play is assigned to Channel 1 and the drum pads are assigned to Channel 10. When you use auto accompaniment, each part is assigned to Channels 710. When you use the keyboard as the sound source for another MIDI device, all 16 channels are assigned musical instrument parts (Channel 10 is reserved for drum parts only, per MIDI standard). The mixer settings also affect the corresponding MIDI output.
SoL: Turns the current channel on
and all the other channels off. A bar appears over only the current channel. 5. To edit other channels, press or to return to the channel selection screen and repeat Steps 24. To exit the edit mode, press MIXER. The display shows the performance status of the channels as edited.
Editing the Status of a Channel
You can edit the status (on, off, solo) of a channel to delete a specific part or to play a specific part by itself. Follow these steps to edit the status of a channel. 1. Press MIXER. The MIXER indicator and the last selected channel appear. 2. Use + or on the keypad to select the channel you want to edit.

Editing the Parameter

You can change the settings of six parameters such as tone, volume, and pan (relative position of the tone between the left and right speaker channels) for the selected channel. Follow these steps to edit the parameters. 1. Select the channel you want to edit as described in Steps 1 and 2 of Editing the Status of a Channel. 2. Press (ENTER) to enter the parameter edit mode.
3. Repeatedly press or to select the parameter you want to change. Program Change Number (000 to 199) sets the tone assigned to the channel. Note: Channel 10 is reserved for percussion, so only tone numbers 160 (DRUM SET1) through 167 (DRUM SET 8) can be set for Channel 10. Volume (000 to 127) controls the volume of the selected channel. Pan (000 to 127) controls the pan. 000 is fully left, 64 is the center position, and 127 is fully right. Fine Tune (50 to +50) fine tunes the pitch of the selected channel in cent units. A cent is one hundredth of a semitone. There are 12 semitones per octave. C (Coarse) Tune (12 to +12) coarsely tunes the pitch of the selected channel in semitone units. Express (Expression) (000 to 127) controls the volume of the selected channel. Similar to the volume setting, this is often used to control crescendo/decrescendo. 4. Use the number buttons or + or to change the parameter setting. 5. To edit other channels, press to return to the channel selection display, select the channel, then repeat Steps 24. 6. To exit the parameter edit mode, press MIXER.
USING THE CUSTOM TONE SYNTHESIZER
The keyboards custom tone synthesizer lets you create up to 32 of your own original tones. To create a user tone, you simply select one of the keyboards 200 preset tones, change its parameters, then store the new tone in any memory location from 168199. You select and use a user tone the same as a preset tone. Notes: You cannot use tones 160167 (drum set tones) as base tones. The preset tone you use as the basis for a user tone is not changed. The tone locations 168199 are not empty (before you store user tones there). They initially contain duplicate versions of tone numbers 128 159. The user tone you store in any of those locations replaces the existing tone. If you delete a user tone, the keyboard automatically restores the initial, duplicate tone there. The parameters you can change are divided into four groups. For the details of each parameter, see Creating and Storing a User Tone on Page 21. Tone Characteristic Waveform PCM Set Volume Characteristic Amp Envelope Set Tone Pitch Pitch and Pitch Envelope Set Tone Characteristic Attack Rate, Release Rate, Level, Touch Sensitivity, and Pan
Understanding 1DCO and 2DCO Tones
A Digital Controlled Oscillator (DCO) controls the sound output of a digital signal. Some of the keyboards built-in tones are simple tones (1DCO), and some are layered tones (2DCO). When you select a 2DCO tone as the basis for creating a user tone, you need to change the parameters of both tones. When you select a layered tone, dCo1 appears, indicating that this is the first tone of a layered tone.

REAL-TIME RECORDING

With real-time recording, the notes are recorded as you play them on the keyboard. Before you start, read these tips. To record without an auto-rhythm, skip Step 5 of Real-Time Recording. Recording starts when you press a key. To start recording with synchro start, press SYNCHRO/ENDING instead of START/STOP in Step 5 of Real-Time Recording. Recording starts when

Using the Memory

3. Press CHORD/1 to select Track 1. While the keyboard is in memory record mode, the level meters for channels 11 through 16 correspond to memory tracks 1 through 6. When all four bars are lit, that channel has something in memory: if only one bar is lit, that track is empty. 4. If desired, you can change these settings: tone number rhythm number tempo MODE Note: Do not change the tempo unless you already know the desired tempo. Pressing START/STOP to hear the tempo causes recording to begin. 5. Press START/STOP to start recording. 6. Play the keyboard. You can also record auto accompaniment chords, the drum pad, pitch bender, and pedal operations. 7. Press START/STOP to end recording. If you make a mistake, press START/ STOP to stop recording and begin again from Step 1, or you can edit the contents. See Editing Memory Contents on Page 33. Press after you select Track 1 in Step 3 to use the drum pads. That way, you can also start recording by playing a drum pad.
This data is stored on Track 1 along with the notes you played: tone number rhythm number rhythm controller (INTRO, NORMAL/ FILL-IN, etc.) operations pitch bender operations pedal operations drum pad operations See Recording Multiple Tracks on Page 31 to record on the other five tracks. Notes: When you record on a track that contains data, the new recording replaces the previous recording. The touch response setting (on/off) is not recorded. However, the strength of the strike is recorded. Channel 1 mixer parameters are automatically recorded to Track 1. The memory can store a total of about 4,900 notes. If the remaining memory is less than 100 notes, the measure and beat numbers flash. When memory becomes full, recording automatically stops (and autoaccompaniment or rhythm stops playing, if used). Memory contents are saved as long as power is supplied to the keyboard. Unplugging the adapter without batteries or with weak batteries erases the memory. To prevent data loss, connect an adapter before replacing the batteries.

The rhythm number and INTRO, SYNCHRO/ENDING, NORMAL/FILLIN, and VARIATION/FILL-IN operations are stored on Track 1, along with the notes you played. See Recording Multiple Tracks on Page 31 to record on the other five tracks.
Specifying Chords in the Normal Mode
To enter chords when MODE is set to NORMAL during step recording, you must specify them using a method other than Concert Chord or Fingered. That way, you can enter 18 chord types using only two keys. While holding down the desired chord root key, press the chord key to specify the chord. The root and chord types are labeled above each key. The chord root letter and type of chord also appear as you play a chord.
Specifying the Length of a Note
During step recording, use the number buttons (or + or ) to specify the length of each note. Use numbers 1 through 6 to specify whole notes (1), half notes (2), quarter notes (3), eighth notes (4), 16th notes (5), and 32nd notes (6).
Hold down 7 (dot) or 9 (triplicate), then press 1 through 6 to enter the lengths of the notes. To enter a tie, press 8 and enter the first then the second notes. To enter a rest, press 0 then use numbers 1 through 9 to specify the length of the rest.
RECORDING MULTIPLE TRACKS
In addition to Track 1, where you record auto accompaniment as well as keyboard play, there are five other melody tracks that you can use to record melody parts only. You can record different tones on these tracks and build a full ensemble of instruments. You can play back what you already recorded on Track 1 (or any other track) while you record on Tracks 26.

Using MIDI

Your keyboard includes a feature called MIDI (Musical Instrument Digital Interface). MIDI is the universal standard for sending and receiving performance data between all types of electronic musical
instruments, regardless of the manufacturer. Using MIDI, you can play music on your keyboard and another instrument at the same time while pressing the keys on only one, record your music to a se-

Using MIDI

quencer, acquire a wider selection of preset tones from a sound module, and much more.
MAKING THE MIDI CONNECTIONS
To connect your keyboard to another MIDI-equipped device, you must use a MIDI cable (available at your local RadioShack store). Cautions: Always turn off power to your keyboard and the other MIDI device before you connect or disconnect MIDI cables. As you make the cable connections, be sure to align the MIDI cable pins with the matching holes on your keyboards MIDI OUT and MIDI IN terminals. If you have trouble plugging in the cable, do not force it! You might damage the plug or the instrument. To send MIDI data from your keyboard, use a MIDI cable to connect the keyboards MIDI OUT terminal to the other devices MIDI IN terminal. To receive MIDI data on your keyboard, use a MIDI cable to connect the keyboards MIDI IN terminal to the other devices MIDI OUT terminal. Note: You do not need to make both connections if you are only either sending or receiving.

ABOUT MIDI

Every MIDI-equipped instrument has MIDI OUT and IN terminals, and some also have a MIDI THRU terminal. Each of these terminals serves a different purpose. MIDI OUT sends MIDI data to (talks to) the other MIDI instrument(s). MIDI IN receives (listens to) MIDI data sent by the other MIDI instrument(s). MIDI THRU lets you connect (network) additional MIDI instruments, and sends along to other MIDI devices a copy of all data it receives through its MIDI IN terminal. Your keyboard has MIDI OUT and MIDI IN terminals. The cable that connects MIDI devices does not actually carry sound between them, like a speaker wire carries sound from a receiver to a speaker. Instead, MIDI-equipped devices communicate with each other using digital codes (instructions). One MIDI device sends digital instructions representing exactly what is being played on it. The other MIDI device receives and translates those instructions, then produces (or records) the sound exactly as it was played on the first device. Note: Connecting your keyboard to another MIDI device requires a MIDI cable (not supplied). See Making the MIDI Connections.

MIDI DATA

Your keyboard can send and receive several different types of MIDI data. The keyboards tones, rhythms, and other types of MIDI data are sent automatically as you play.
Notes: The keyboards prerecorded tunes cannot be sent as MIDI data. For detailed specifications of the MIDI function, see the MIDI Implementation Chart on Page 46. Note On/Off specifies which keys are pressed (Note On) or released (Note Off). Also includes how loud a note is played as a value from 0 to 127. Notes: The pitch of a note depends on the tone that is being used, as shown in the MIDI Implementation Chart on Page 46. If the keyboard receives a request to play notes outside of its range (higher or lower), it automatically selects the same note in the nearest octave. Program Change specifies the tone. Pitch Bend supplies pitch bend information. The keyboards pitch changes as it receives a Pitch Bend message through the MIDI IN terminal, and the keyboard sends pitch bend information through the MIDI OUT terminal as you rotate PITCH BEND. Control Change adds effects such as vibrato and volume changes applied during keyboard play. The message includes a control number (the effect type) and a control value (the on/off and depth of the effect). Here is the data that can be received with this keyboard and the corresponding control number.

See the owners manual that comes with the connected device for details. The keyboard automatically exits the data transfer mode after all the data is received.
Note Number This number represents each key of the keyboard. The lowest number (0) is five octaves below middle C. Since the keyboards lowest note is two octaves below middle C and the highest is three octaves above middle C, your keyboard can send a note number between 36 and 96. But, it can receive all 0 through 127 note numbers, so those keys outside the keyboards key range are interpreted as notes inside the key range. Velocity This number shows how fast the key was pressed, or how loud the note should sound. 1 is the lowest velocity, pianissimo; 127 is the loudest, fortissimo. 0 means the key is released. 9n This means that the Note On message is 9 hexadecimal, and n is the channel number. For example, if you select Channel 16 and press Key D in mezzo-piano, 9E (E is 15 in hexadecimal; note that Channel 1 is 0 in MIDI data) is first sent from MIDI OUT, then 3D (decimal 61) is sent as the key number, finally 21 (decimal 33) is sent as velocity. Pitch Bender The keyboard sends and receives pitch bending signals. Control Change This feature sends data on various controllers, each having its own number. For the details of each parameter, see MIDI Data on Page 35. Program Change This feature changes the preset sounds. Each sound number corresponds to a program number between 0 and 127. System Exclusive This feature sends special signals unique to the key39
NOTES ABOUT THE MIDI IMPLEMENTATION CHART
The MIDI Implementation Chart on Page 46 illustrates the details of the keyboards MIDI function. An O in the chart means that the keyboard has this feature; X means it does not have this feature. This section explains what the keyboard can do. Basic Channel MIDI uses up to 16 channels to exchange data. As in a TV broadcast, different channels send different data. Mode The chart shows that Mode 3 is OMNI OFF, POLY. This means the keyboard sends and receives polyphonic data on only one channel at a time.

board. For details, see MIDI Data on Page 35. System Real Time Clock is like a metronome to send the synchronizing signal. System real time commands send three kinds of signals start tells the keyboard to start playing from the beginning, stop tells all the synchronized instruments to stop playing, and continue is similar to start, but it signals the
music to begin at whatever point it was last stopped. All Notes Off This feature is a kind of panic button: it stops the sounds currently playing. The keyboard only receives this message. Active Sensing This means the keyboards sound turns off in the event the connection cable to MIDI IN terminal is accidentally disconnected.

Troubleshooting

If your keyboard is not performing as it should, these suggestions might help. If you still cannot solve the problem, take the keyboard to your local RadioShack store for assistance.
Trouble No sound, even if keys are pressed. Possible Cause The keyboard has turned off automatically. Volume is turned down. Headphones connected. Power supply problem. Remedy Set MODE to OFF then ON. Repeatedly press MAIN VOLUME to increase the volume. Disconnect headphones. Check the power supply. Are battery symbols (+/) facing correctly? Are the batteries fresh? Is the AC or DC adapter connected properly? Set MODE to NORMAL or CONCERT CHORD. Press 3 or 4 keys to form a chord while MODE is set to FINGERED. Repeatedly press VOLUME to increase the volume. Replace the connection cord.
You are pressing too few accompaniment keys while MODE is set to FINGERED.
No sound when connected to an external amplifier.
Volume is turned down. Defective connection cord.

Troubleshooting

Trouble No sound when receiving and playing MIDI data. The key or tuning does not match when playing along with another MIDI instrument. Bass notes in General MIDI data are sent out one octave lower. Sounds sent to another MIDI device by the keyboard do not sound correct.
Possible Cause MIDI cables are not connected properly. The tuning or transpose parameter is set to a value other than 0 or 00. Tone map parameter is set to N. The other devices MIDI THRU function is turned on.
Remedy Check the connection. Set the tuning or transpose to 0 or 00.
Set the tone map parameter to
G (see Changing MIDI Settings
on Page 37). Turn off the MIDI THRU function on the other device.
To enjoy your MIDI Keyboard for a long time: Keep the keyboard dry. If it gets wet, wipe it dry immediately. Use and store the keyboard only in normal temperature environments. Handle the keyboard gently and carefully. Do not drop it. Keep the keyboard away from dust and dirt. Wipe the keyboard with a damp cloth occasionally to keep it looking new. Modifying or tampering with the keyboards internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your keyboard is not performing as it should, take it to your local RadioShack store for assistance.
