Group mode – does not work
The Matrix 1000 offers a GROUP Mode for cascading several Matrix 1000 or 6 to archive 12, 18 or more voices
instead of the default 6. This Group Mode can NOT be used in conjunction with the Programmer (unless making
a workaround with the PolyChainer, see below). In theory you can hook up the Programmer with 2 or more
Matrixs using a Midi Patchbay or a Midi-Y-splitting cable. But there is a technical problem:
Normally the Matrix while being in Group mode forwards all Midi messages on it's MIDI IN to it's MIDI OUT for
the 2nd Matrix. Now unfortunately the Matrix seems to destroy SysEx parameter change commands in between.
The command „F0 10 06 06 03 20 F7“ sent to IN comes out as „F0 10 06 F0 F7“ which does not make any sense.
This is tested with OS versions 1.11, 1.16 and 1.20.
It is interesting that SysEx-Data which is not addressed for the Matrix gets forwarded undestroyed. It looks like
the Matrix is so busy changing it's internal sound parameters that it does not have enough capacity to forward
the command to MIDI OUT without errors.
Without the 2nd Matrix to receive correct parameter change commands, the whole group mode does not make
any sense. Additionally there are communication issues between Programmer and first Matrix due to the
problem described above.
Solution
Since 2020/05 we offer a little midi tool called
PolyChainer
. It distributes the midi notes and parameter change
data from the Programmer individually between both connected Matrix. This also works with two Matrix 6 or
1000 and 6 mixed. For more details and the full featurelist please check out the product's page on our website.
