Yamaha SY-77, Operating Manual

Page: 175 / 268

MULTI EDIT MODE
Since the SY77's sequencer can be used at any time
even while editing a voice or multi, you can use this
function to edit one of the voices in a multi while
that multi is being played from the sequencer. This
capability is very useful, since it allows you to edit a
voice while it is being played in a musical context
with other instruments.
Off Voice: Each channel of the multi can use any
voice from internal, card, or preset memories, or
can be turned "off". When turned off, the multi
will not play a voice in response to data on that
channel.
This allows you to play an external MIDI
tone generator from certain channels of the
SY77's built-in sequencer without sounding the
SY77's own tone generator for those channels.
If you set the output level of an unwanted
channel of the multi to 0 (see Multi edit 2. Voice
volume) it will not be heard, but will still use the
SY77's tone generator whenever notes on that
MIDI channel are received, and will therefore
reduce the simultaneous notes available for the
other voices. This is why you should turn
unneeded channels of the multi "off".
To turn a channel off, hold the SHIFT button
and press a memory select button 1-16. To
restore the previous voice selection for that
channel, hold SHIFT and press the corresponding
memory select button 1-16 once again.
Remarks: In multi play mode the SY77 keyboard
will normally play only the channel of the multi
which matches the Keyboard MIDI Transmit
Channel setting made in MIDI utility 1. Channel
set. However in multi edit mode, the SY77 key-
board will play the voice where the cursor is
located in this Voice Select job. This will remain
in effect as long as you are in multi edit mode.
