sending the stream of Active Sense data to the other slaves in the
system, keeping "the line busy". If any of the other slaves in the
system have Active Sense, they will be able to use this stream of
information coming from the MATRIX-GR, thus prevent their own
notes from locking on.
I MPORTANT NOTE:
Some older synthesizers, perhaps due to
the simplicity of their M IDI implementation, may not be able to
properly interpret Active Sensing data received at their MIDI I N. If you
experience strange symptoms or erratic behavior from a synthesizer
connected as a slave to the MATRIX-GR - such as its control panel
locking up, memory crash, etc. - tu rn Active Sense in the MATRIX-GR
OFF or disconnect the slave from the MATRIX-GR's MIDI OUT and
use MIDI THRU instead.
PATCH MAPPING
M IDI Interfacing, as we have seen in this section of the manual, provides for
a number of extremely useful performance functions to be shared among
the various instruments connected together in what is called a M IDI
"system". One of these handy features is the ability of the Master controller
to send a command to the instru ments that it is driving to change from their
current patch to a new one.
A limitation in this feature exists, however, in that all instruments in the
system must change to the same MIDI Patch Number. Each instru ment, of
course, can be programmed to play a different sound but there is really no
easy way to set up a logical arrangement so that each instrument will change
to the patch that compliments the rest of the instruments.
For example, under the present MIDI system, you must re-program each
synthesizer by shuffling programs around in memory so that the same patch
number in each unit can be used to recall the sounds you want. If the Master
controller sends out MIDI Patch Number 23, every other synthesizer in the
line must recall its own "Patch 23". If Patch 23 in the MATRIX-GR, as one of
these instruments, is not the sound that you want to use in conjunction with
the others, you must replace Patch 23 with another existing patch or re
program Patch 23 entirely from scratch. Just think of how much time it would
take to re-organize the 1 00 patches in the MATRIX-GR so that they
correspond to and compliment the patch played on the Master, let alone
work that would be required to re-organize three or four instruments in your
rig.
PATCH MAPPING solves this problem and allows the Patch Change feature
of MIDI to become really useful. Patch Mapping gives you the ability to "re
arrange" your patches in the MATRIX-GR without actually re-arranging them.
This is accomplished by using the "Table" in Parameter 1 G P MAP EDIT to
make the MATRIX-GR respond
to any patch you want, regardless of
what Patch Number command is sent to it from MIDI.
Patch
Mapping also provides the means to transmit selective patch change
commands to other instruments in the system that are slaved to the
M ATRIX-GR.
