That KEY1 functions as a random key is a
special case of sequential key, which com-
bines a particular arrangement of sub-group
playing sequence.
Reset of KEY1 playing sequence
If a sub-group of KEY1 group is being played
and one of KEY2~KEY12 is triggered, the
playing sub-group will be terminated, and
the newly triggered key group is played in-
stead. The first sub-group will start playing
when KEY1 is retriggered. In other words,
the KEY1 playing sequence is reset when-
ever a key other than KEY1 is triggered (see
Figure 1).
Sub-group selection
When KEY1 is triggered with pulses, a de-
sired sub-group can be selected by controlling
its corresponding pulse number. However,
the features of KEY1 have to be set in the fol-
lowing ways:
sequential or random
retriggerable
minimum key debounce time
( 700 s, f
OSC
=96kHz)
For instance, if sub-group 1-3 is the previous
playing group, sub-group 1-5 will start playing
after 2 pulses are applied to KEY1, and so on.
To make easy selection of KEY1 sub-groups,
one of KEY2~KEY12 should be programmed
as silence. Then this silence key has to be
triggered to reset KEY1. By so doing, the
playing sub-group of KEY1 is directly speci-
fied by the pulse number applied to KEY1
(see Figure 2).
KEY12 as a stop key (by mask option)
When KEY12 functions as a stop key, any
voice output can be stopped by pressing
KEY12.
KEY1~KEY11 as a repeat key
KEY1~KEY11 all function as repeat key if
one of the eleven keys is set as a repeat key.
In other words, once the mode of one of
KEY1~KEY11 is determined, the remaining
10 keys are set accordingly.
As a repeat key, the sections included can be
played sequentially or repeatedly till other
key input is triggered. KEY12 has no other
choice but functions as a stop key when
KEY1~KEY11 are set as repeat keys.
