PLAY INSTRUMENT KEYS TO ENTER MORE NOTES. USE ACCENT KEY TO
ENTER ACCENTS, +1/YES KEY TO ENTER RESTS, CLEAR KEY PLUS IN-
STRUMENT KEY TO CLEAR MISTAKES.
You can now playback your pattern in the usual way, adjusting the tempo as desired.
Quantize
Basically, quantize determines the smallest note-increments which can be pro-
grammed. The available quantize values are 1/12, 1/24, 1/16, and 1/32. This is
the order in which the values appear when you “scroll through” the quantize values
with the +1/YES key.
When you set the quantize rate to 1/16, the shortest notes that can be entered in
either the real time or the step write modes are 1/16th notes–i.e., the maximum
number of notes that can be entered in one 4/4 bar is 16.
QUANTlZE Applied to the Real Time Write Mode
In the real time write mode, this has an “error correcting” function. In other words,
if your timing while playing on the instrument keys is a little off, the off-time beats
will be recorded at the nearest quantized beat. Thus, for more subtle rhythms, it
is best to select a higher quantize rate (1/32 or 1/24) while simpler rhythms can
be entered more accurately and rapidly, using the lower quantize rates (1/12 or
1/16).
QUANTIZE Applied to the Step Write Mode
In the step write mode, the quantize function can save time by minimizing the number
of steps required to enter each part. If, for example, the quantize rate is set to 1/32,
the beat count will proceed from 1 to 32 per bar. This is fine if 32nd notes are to
be entered, but a regular 8-beat bass drum line would require the entry of three
rests between each drum beat. Generally, then, it is better to use a lower quantize
rate, and enter the simpler rhythms (say, bass drum and snare). You can then switch
to a higher quantize rate using the BEAT EXCHANGE function (described later in
this chapter) and enter more subtle or complex rhythms (for example, a syncopated
hi-hat part).
For entering triplet patterns, you’ll need to use the 1/12 or 1/24 quantize rates.
Here’s our basic 4/4 time pattern, using the 1/12 quantize rate to program 1/12th
notes (quarter note triplets) and create a slow blues pattern.
