Akai S950 Operator's Manual page 50

The ONE-SHOT function caters for use of the 5950 with certain drum machines
whose note on message is so fast, it cannot trigger samples in the 5950
properly. If you have such s drum machine and don't get a sound even though
everything seems to be working o. k., switch this to ON as this may cure the
problem. If it doesn't, you may have some other problem.
The next page allows you to set the MIDI channel for individual keygroups and
the display reads:
The 5950 has a very flexible MIDI Implementation. Any keygroup can be
assigned to any of the 16 MIDI channels and this allows you to set up a
program for mufti-timbral operation where each sound plays a different part
on a different MIDI channel.
This page operates as follows:
It !s possible to 'offset' a keygroups MIDI channel against the 5950°s
overall MIDI channel as set !n the main MIDI pages. Say, for example, the
5950 is set to an global MIDI channel of I with OMNI OFF, in this page of
EDIT PROGRAM, you could offset a keygroup by a factor of 3 so that !t would
respond to any incoming messages on MIDI channel 4 (i.e. base channel+3=4>.
Similarly, if the 5950's global channel was set to 5 with OMNI OFF, an offset
of 7 would place that keygroup on MIDI channel 12. In this way, any keygroup
can be addressed on any MIDI channel. A typical example would be where you
wish to run a few instruments on separate MIDI channels for mufti-part
sequencing.
You may have drums !n keygroups 1 to 5, a bass sound !n keygroups 6 to 8, an
electric piano sound !n keygroups 9 to 12 and a simple synth brass sample !n
keygroup 13. The only way to run these sounds from a sequences without the
MIDI OFFSET function would be to ,map them out so that the keygroups do not
overlap each other in their lowest and highest note assignments. This is
actually a perfectly valid way of doing this except that you would only have
limited note ranges for each instrument.
Better would be to map these instruments out as they should over the entire
keyboard range ° if you were to play them with MIDI OMNI ON, all those
samples would sound together. By pressing the main MIDI mode and switching
OMNI to OFF and selecting MIDI channel 1, you can now go back into EDIT
PROGRAM, go to Page 16 and give these keygroups their own MIDI channel. For
instance, as you want the drums on MIDI Channel i, you needn't offset
keygroups 1-5, the bass keygroups you can offset by a factor of 1 which will
place them on MIDI channel 2, the piano keygroups can go on channel 3 so
offset those keygroups by a factor of 2 and the synth brass can be offset by
3 so that !t responds to MIDI channel 4.
If that sounds complicated, it isn't and here's how you achieve that.
Move the cursor to the KG field using the 'cursor >' button and select the
appropriate keygroup. Press 'cursor >' again so that the cursor is on the '
MIDI ch' field and change the data using the CONTROL knob or the keypad.
Press the 'cursor <° button and change the keygroup and press 'cursor )'
again to change that keygroups MIDI channel offset value. Repeat this process
for all the keygroups in the program.
