MIDI Matrix 2
|
Published in Electronics and Beyond (now owned by Elektor) issues 160 and 161
Offering 8 MIDI channels, microprocessor-controlled, MIDI-controlled patch changes, storage of 64 patches in non-volatile storage, LED displays, simple user interface ... the list goes on.
Data files for the Microcontroller and CPLD are now available for those with suitable IC programmers. Note: this is a ZIP file which requires unzipping before it can be used. There are plenty of unzipping tools available on the web.
Thanks to Arto Koivisto I now have PDF scans of the two-part magzine article:
Part 1 (introduction, schematics) and
Part 2 (construction, operation, parts list).
