WitchMaster Posted November 27, 2013 Report Share Posted November 27, 2013 Hi! I have two synths I would like to be able to control wirh MIDI. Both synths have matrix-type keyboards. I have seen examples of how to use reed relays for every key and that is one option, but is it possible to connect to the matrix (pun intended) to control these synths? How can this be done, didn't find any example of this, just how to read keyboard matrices, not the other way round. Thanks for any help in advance! - Mikael Quote Link to comment Share on other sites More sharing options...
TK. Posted November 28, 2013 Report Share Posted November 28, 2013 Hi Mikael, it is possible, but requires some reverse engineering. It especially has to be considered, that there is no "one approach fits all". E.g. if the keyboard is scanned with >= 50 uS, a microcontroller might be sufficient to emulate the keyboard. For higher scan rates, a FPGA based approach might be better. In any case, you need good programming skills and an oscilloscope for debugging to implement such an emulation your synths. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
WitchMaster Posted December 16, 2013 Author Report Share Posted December 16, 2013 Thanks Thorsten! I will stick to the reed relays. :) Quote Link to comment Share on other sites More sharing options...
