Hi,
I built a hardware controller for Marion MSR2, Tetra, the Shruthi etc ... If a french user can send me a matrix 1000 for a few days, I can try to make a template for it. Sysex seem as comprehensive as those of Marion.
The project name is ll113, you will find all the info on the net. Without CV / Gate, the controller costing no more than € 150 and you have a bonus four sequencers, arpeggiator etc...
Regards
