Precautions
Your QY20 will give you years of reliable service if you follow the simple rules given below:
Location Do not expose the instrument to the following conditions to avoid deformation, discoloration, or more serious damage. Direct sunlight (e.g. near a window). High temperatures (e.g. near a heat source, outside, or in a car during the daytime). Excessive humidity. Excessive dust. Strong vibration. Power Supply Turn the power switch OFF when the instrument is not in use. If you use an AC power adaptor, unplug the adaptor from the AC outlet if the instrument is not to be used for an extended period of time. Unplug the AC power adaptor during electric storms.
Avoid plugging an AC power adaptor used with the QY20 into the same AC outlet as appliances with high power consumption, such as electric heaters or ovens. Also avoid using multi-plug adaptors since these can result in reduced sound quality and possibly damage. Turn Power OFF When Making Connections To avoid damage to the instrument and other devices to which it is connected (a sound system, for example), turn the power switches of all related devices OFF prior to connecting or disconnecting audio and MIDI cables. Handling and Transport Never apply excessive force to the controls, connectors or other parts of the instrument. Always unplug cables by gripping the plug firmly, not by pulling on the cable. Disconnect all cables before moving the instrument.

Select the SONG mode display (use the [MODE] key, as described above), use the cursor keys to select the transpose parameter ("Trns" on the display), then try using the [-1/NO] and [+1/YES] keys to change its value. Set it back to "+00" before continuing.

[MENU] and Function Keys

The [MENU] key calls a menu of functions or sub-modes that can be accessed from the current QY20 mode, and the function keys (the small round yellow keys) select the corresponding item from the menu that appears on the display. Select the SONG mode display (use the [MODE] key, as described above), then press the [MENU] key. You should sec the menu shown to the left. Next press the top function key (the one immediately to the right of "Job" on the menu) to call the SONG mode Job List:
You can now use the cursor keys (up and down only) to select the various items in the Job List. Leave the display as it is for now, and read about the [ENTER] key, below.
Getting to Know the QY20: How the Controls Work [ENTER] Key
In addition to "entering" chords in SONG and PATTERN modes (which we'll learn about later), the [ENTER] key is used to "enter" a selected menu function. Assuming that you've gone through the "Try this:" procedure for the [MENU] and Function keys, above, you should now have the SONG mode Job List on your QY20 screen. Use the cursor keys (up and down only) to select job number 2 "Copy Meas". Now press the [ENTER] key to actually engage the copy measure job the display should appear as shown to the left. Since we don't really want to use the copy measure job, press the [MODE] key to go back to the SONG mode. You could also press the top function key (next on the display) to first move back to the to "Exit Job List, and then again to return to the SONG mode.

Sequencer Keys

The sequencer keys control recording and playback in the SONG and PATTERN modes, and allow you to locate a specific measure within a song or pattern. Their layout and functions arc similar to the transport controls on a tape recorder.

Micro Keyboard

This tiny 2-octave keyboard makes it possible to program the QY20 anywhere, anytime, without having to connect an external MIDI keyboard. It's even polyphonic, so you can directly enter chords as well as single notes. The only thing it lacks is velocity sensitivity. The QY20 does, however, accept velocity information from an external MIDI keyboard. When programming the accompaniment tracks the micro-keyboard is also used to specify the chord roots and types to be entered.

Enter a chord. Note that the lower octave of the micro-keyboard has chord root names "E" through "D" marked on the keys, and the upper octave keys are marked with a variety of chord types.
To enter a chord, press the key corresponding to the desired chord root, then the key corresponding to the desired chord type (the chord type keys alternately select the lower and upper chord types marked. watch the display), and finally the [ENTER] key. The chord is actually entered only when the [ENTER] key is pressed. Until the [ENTER] key is pressed, the newly specified chord root and type will flash on the display.
Actually, you can press the chord type key and then the root key, the order doesn't matter.
The"- - -"chord type marking is a special "non-ABC" type that can be used to create accompaniment patterns without the harmonic limitations of the ABC system. See page 95 for details. If you enter only the chord root without a chord type, the result will be a major chord.
Try out the various chords with different patterns. During playback you can move the cursor up to the pattern number, select a different pattern, then move the cursor back to the chord symbol arid try different chords with the new pattern.
If you move the cursor to the "Trns" (transpose) parameter, you can use then [-1] and [+1] buttons to transpose the pitch of the entire pattern up or down in semitone increments over a range of two octaves. A transpose setting of "+00" produces normal pitch.
Stop playback by pressing the key. You can also stop playback after an appropriate ending by selecting the ENDING section (the cursor must be on the pattern number or section name to do this).

Muting Tracks

The mute "buttons" below each track name can be used to mute (turn off) the corresponding track, either while playback is stopped or running. Move the cursor to the appropriate mute button, then press [+1/YES] to mute that track, or press [-1/NO] to turn a muted track back on.

want to go to.

Press the key to exit from the step record mode and return to the normal SONG play mode.
"Pat" Step Record Pattern Changes
Here's how the STEP record pattern display will look if you've selected an empty song (the appropriate pattern data will appear if the selected song contains data).
Moving Around & Entering Data As usual, the cursor keys are used to move the cursor to the location at which you want to enter data, and the [-1] and [+1] keys are used to actually enter or change data. The cursor keys also move you forward or backward through the song: moving the cursor past the bottom of the screen accesses subsequent measures, while moving it above the top of the screen accesses the preceding measures (if there are any). In the pattern display moving sideways takes you to the time signature, pattern number, and section parameters. In all of the STEP record displays the sequencer keys can also be key used to move forward or backward through the song. The takes you directly to the first measure.
Pattern Number and Section Any pattern number from 001 through 200 (presets and user patterns) can be entered for each measure. Only the preset patterns, however, have sections. The pattern name appears to the right of the pattern number. Only one pattern & section can be entered per measure, and that pattern will begin playing from the beginning of the measure at which it is entered. A pattern entered once will continue to play until a different pattern is entered. If you want to change sections without changing the pattern number, only the section need be entered. In the example display to the left the intro section of pattern 006 plays for the first measure, the normal section of the same pattern is selected in measure 2. Although the default time signature for the selected pattern is automatically selected, the time signature value for each measure can be changed as required. The available time signatures are:
1/16.16/16 1/8..16/8 1/4.. 8/4

Time Signature

If a time signature is selected that results in shorter measures than the pattern default, the pattern will be truncated (cut short) accordingly. If the selected time signature results in longer measures than the pattern default, the pattern will be repeated to fill the specified measure length. Erasing Pattern Changes The function key immediately to the right of "ers" on the display can be used to erase the time signature, pattern number, or section data at which the cursor is located. If you erase a time signature change, the default time signature value for the current pattern will be automatically re-selected.

Press to erase pattern, section, or time signature change at cursor location.
"Chd" Step Record Chord Changes
Here's how the STEP record chord display will look if you've selected an empty song (the appropriate chord data will appear if the selected song contains data).

Chords

One chord can be entered per quarter note. Place the cursor at the required quarter-note division on the display and enter the chord via the micro-keyboard in the normal way (see page 48). In the example display to the left, an A major chord is entered on the First beat of the first measure, a B minor seventh on the third beat of the first measure, and a D major on the first beat of the second measure.
Specifying the Bass Note For a Chord
You can specify the bass note to be used with any chord by using the [OCT DOWN] key (note the "BASS" marking below the key). Enter the chord in the normal way, press the [OCT DOWN/BASS] key (a slash will appear below the chord name), then press the key on the micro-keyboard corresponding to the desired bass note (the bass note will appear to the right of the slash).
You can add bass notes to existing chords without having to re-enter the entire chord by simply moving the cursor to the chord and using the [OCT DOWN/BASS] key to specify the bass note. A bass note can be removed from a chord by placing the cursor at the chord and either re-entering the chord or pressing the [OCT DOWN/BASS] key twice.

Syncopated Chords

Example: Enter a syncopated D chord.
Chords can be syncopated (i.e. the chord actually begins an eighthnote before the beat on which it is entered) by using the [OCT UP] marking below the key). Enter the chord in the key (note the normal way, then press the [OCT UP] key (a syncopation symbol will appear below the chord name).
You can add syncopation to existing chords without having to re-enter the entire chord by simply moving the cursor to the chord and pressing the [OCT UP] key. Syncopation can be removed from a chord by placing the cursor at the chord and pressing the [OCT UP] key.

Erasing Chords

The function key immediately to the right of "ers" on the display can be used to erase the chord at which the cursor is located.
The Chord Display During Playback Chord bass notes and syncopation marks appear on the display as shown in the SONG playback mode.

Set time signature and pattern length (new patterns only). If you are recording a new pattern, move the cursor to the time signature and pattern length parameters and set as required.
The time signature and pattern length parameters can not be changed if the selected pattern already contains data.
Move the cursor to the track area of the display, and then. shift the cursor sideways to select the track you want to record: "C1" = chord 1, "C2" = chord 2, "Ba" = bass, "Dr" = drums. If you are recording a new pattern or track, use the [-1] and [+1] keys to select the voice you want to use for that track once the track has been selected. If you don't intend to use a track, set the voice number to "OFF." Move the cursor vertically to move to other areas of the screen. An underline will remain below the selected track.
Cursor here to select the C1 (Chord 1 ) track. Number & name of voice assigned to current track shown here.
key to begin recording. The step record display Press the shown below will appear.
Set the note parameters as required.
Move the cursor to the note, velocity, and gate time parameters and set as required using the [-1] and [+1] keys for the first (or next) note to be entered.
The velocity and gate time settings in the step record display correspond to the following numeric values in the edit displays (to be described later): Velocity " p " = 56 "mf" = 88 "f" = 120 "Staccato" = 50% normal note length. "Normal" = 90% normal note length. "Slur" = 99% normal note length.

Gate Time

Enter a note.
Once the note parameter have been specified, the note can be entered simply by playing the appropriate key on the micro-keyboard (or on your external MIDI keyboard). A note symbol appears on the note display and the note pointer advances to the next note position. The note symbol always appears as a 1/4-note, regardless of the actual note entered (chords are also indicated by the 1/4-note symbol). Here's how the display will look after two 8th notes have been entered.
The Note Display The note display shows up to four 1/4-notes worth of data at once (that's one measure in 4/4 time). If the selected time signature results in more than four 1/4 notes per measure, then the display will scroll to show the extra notes. On the other hand, if the time signature is 3/4, then the 4th beat is not used and appears as double dashes on the display ("========").
Moving Around In the Note Display You can move the cursor down to the note display (the note pointer will appear filled) and move the note pointer to any position at which you want to enter a note, or to any note that you want to delete. You will actually hear the appropriate note or chord when the note pointer is moved to an existing note symbol. When you move the note pointer past the end of the note display, the next measure will appear. If you move past the last measure in the pattern, the first measure of the pattern will appear.

Copy Measure

First measure in range to be copied (001. 999). Last measure in range to be copied (001. 999).
Source track (TR1. TR4, Chd). Destination track (TR1. TR4, Chd).
Copies a specified range of measures from one track to the specified measure in another track. This operation overwrites the data from the beginning of the specified destination measure with the data from the source measure. Previous data in the overwritten measures is therefore lost. If the "Chd" track is selected, the corresponding chord progression is copied.
Number of times specified range of measures is to be copied (01. 99).
After setting the parameters as required, press [ENTER]. "Are you sure?" will appear on the display. Press [+1/YES] to confirm that you want to go ahead with the Copy Measure operation (Copy Measure is irreversible), or press [-1/NO] to cancel.
The Copy Measure job makes it easy to use phrases or even complete sections (an entire chorus. for example) in more that one place in a song. You can copy a phrase played by one voice, and have it repeated by a different voice later in the song. You can always edit the copied sections to create variations.
Measure at which created measures are to be inserted (001. 999).
Time signature of measures to be created (1/4. 8/4. 1/8. 16/8. 1/16. 16/16).

be created (01. 99).

Creates a specified number of blank measures having the specified time signature for all sequencer tracks (TR1. TR4). The accompaniment tracks are not affected. The created measures are inserted at a specified measure number, and all subsequent measures are moved forward to make room. Always set the time signature parameter to the same time signature as the song, otherwise the difference between the specified time signature and that of the accompaniment tracks makes it impossible to propNumber of measures to erly create the specified measures. After setting the parameters as required, press [ENTER]. "Are you sure?" will appear on the display. Press [+1/YES] to confirm that you want to go ahead with the Create Measure operation, or press [-1/NO] to cancel.
Use create measure when you want to add new material somewhere in the middle of data you've already recorded, without erasing the existing data. First create the required measures, then either copy the data from existing measures using the Copy Measure function, or record new data as required.

Quantize

Last measure in range to be modified (001. 999). Quantize note length (32nd note, 16th note triplet, 16th note. 8th note triplet, 8th note, 1/4-note triplet, 1/4-note, 1/2-note triplet, 1/2-note).

Although you can remove events individually in the edit mode (page 145), the Remove Event job makes it simple to remove all occurrences of the specified event within the specified measure range in one operation. This is particularly convenient when removing slow pitch bends or volume changes that may employ many individual events to create a single effect.

Modify Velocity

Last measure in range to be modified (001. 999). First measure in range to be modified (001. 999). Track (TR1. TR4). Velocity ratio (000%. 200%). Amount of velocity change (-99.+00.+99).
Increases or decreases the velocity values of all notes in the specified track and range of measures. The "rate" parameter sets the ratio between the lower and higher velocity values. A setting of "100%" maintains the original relationship between the notes, lower values produce a narrower dynamic range, and higher values produce a broader dynamic range. The "offset" parameters determines the amount of velocity change. "-" settings reduce the velocity while "+" settings increase the velocity. After setting the parameters as required, press [ENTER]. "Are you sure?" will appear on the display. Press [+1/YES] to confirm that you want to go ahead with the modify velocity operation, or press [-1/NO] to cancel.
The Modify Velocity job is a great way to "soften" the sound of material that has too great a variation between the softest and loudest notes, or, conversely, to add extra punch to dull-sounding material. Experiment with the parameters to get a feel for what they do.

Modify Gate Time

Last measure in range to be modified (001. 999). First measure in range to be modified (001. 999). Track (TR1. TR4). Gate time ratio (000%. 200%). Amount of gate time change (-99. +00. +99).
Increases or decreases the gate times (length) of all notes in the specified track and range of measures. The "rate" parameter sets the ratio between the shorter and longer gate time values. A setting of "100%" maintains the original relationship between the notes, lower values produce a narrower gate time range, and higher values produce a broader gate time range. The "offset" parameter determines the amount of gate time modification. "-" settings shorten the gate time while "+" settings increase the gate time. After setting the parameters as required, press [ENTER]. "Are you sure?" will appear on the display. Press [+1/YES] to confirm that you want to go ahead with the modify gate time operation, or press[-1/NO] to cancel.
The Modify Gate Time job can be used to produce a more staccato or legato feel, as required. Experiment with the parameters to get a feel for what they do.

Velocity

This parameter controls the velocity (loudness) of the note. The range is from 001 to 127.

l Deleting Events

Notes and other events (sustain on/off, pitch bend, etc.) can be deleted by placing the cursor at the line corresponding to the event to be deleted, and then pressing the function key next to Del on the display.
Press to delete line at cursor location (note or other event).

Insert Mode Editing

The edit insert mode is used to insert new notes and other events at a specified location in the pattern.
Place the cursor at the insert location.
Move the cursor to the edit line corresponding to (or near to) the location at which you want to insert the new data.
Place cursor at insert location.
Engage the insert edit mode.
Press the [MENU] key and then the function key next to Insert on the display to switch to the insert edit mode.
Press to engage insert edit mode.

Call the event list.

Press for event list.
If the display corresponding to the type of event you want to insert does not appear immediately (the last selected event type will appear), press the function key next to evt on the display to call the insert edit mode event list.
Select the type of event to be inserted.

Top half of event list.

Move the cursor to the type of event you want to insert (see descriptions below), then press the [ENTER] key to call the display for the selected event.
Bottom half of event list.
Set the event parameters.
All events have at least two parameters usually the location of the event (Beat-clock) and the event value. Move the cursor to the event parameters and set as required by using the [1] and [+1] keys. Note that the measure number above the event line will change to indicate the event locations as you change the beat-clock location value (M001. M999).
New notes can be inserted at any specified location. The note range is from C-2 to G8. Gate time and velocity can also be specified.
