CHANNEL MIDI:
Parameters 08, 09, and 10 are midi channel functions. You will locate them on the
parameter chart as CHANNEL MIDI 1, 2 and 3. Again, 1, 2, and 3, refers for zones
one, two, and three. The VALUES of these parameters are midi channels 1 through
16, represented by 01, 02, 03, 04, 05, 06, 07, 08, 09,10,11,12,13,14,15,16, giving
us access to all the midi channels in the specification.
Up to this point you have created a single midi channel. This midi channel runs
across the keyboard. By using this procedure you get one chromatic sound from
the bottom of the keyboard to the top. What happens if you want three sounds
across the keyboard? Well, to start, change each midi channel to a different
VALUE. For example, keep parameter 08 the VALUE of 01, but change parameter
09, to VALUE 02 and parameter 10 to VALUE 03. If you have three sound modules
chained together by midi cables, please set each one to channel 1, then 2, then 3.
If you have one multi-timbral module, set different sounds to channels 1, 2, and 3
(refer to the sound sources' owners manual for the channel change command). At
this point you should have different sounds on three separate zones across the
keyboard. Check this by playing the keyboard. If you do not have the desired
results, check the value of each midi parameter and find your mistake. In the next
section you will learn different ways of using midi channels in conjunction with
parameters 00, split left and 01, split right, giving you totally different control across
the keyboard.
PRESET:
Use parameters 11,12 and 13 for PRESET changes or program changes. There are
100 program changes. The VALUES of these parameters start at 00 and continue
through 99. If the number of the PRESET on the controller does not match the
program number on the sound source, do not worry. You will notice that it may be
one number off. This is recognized by the MIDI standard. Programming these
parameters for each zone is just like programming the previous parameters, only
this time you are sending program changes per zone. You will notice that your
sound source may have more than 100 sounds. If this is the case, look in the
owner's manual for the "program change map". Learn how to use it. In this way
you can send patch changes to sounds higher than 100. For example, if the
controller sends out a PRESET change of 99, the sound on the receiving end might
be 127 or any other number.
