Now that I am able to program the MKS-80 with the Bitstream 3X I am attempting to do the same for other electronic instruments that lack tactile controls. This involves digging into the MIDI implementation of these instruments and then programming the BS3X to send the appropriate values. The first instrument I’m trying this with is the Roland D-50. So far I have had no success in getting the Roland D-50 to respond to the values I’m sending it, but hopefully I get it figured out soon. Here’s an example of what I’d like to accomplish. To create the sound below I used the D-50’s joystick to change the cutoff frequency on the first upper partial while sending it notes via MIDI.
