According to MIDI implementation, seems like it is possible to change one parameter at a time using CC84 and CC85. So I dug out my old proto board with Atmel MCU, some old touchpad and digital pot, and started thinking this over.
And while looking for ways to attach pots to my board, I have found this:
http://the-all.org/tx81z/twopot/index.htmlIt's a simple project, sort of hardware patch editor with an LCD, a couple of knobs and MIDI output to control TX81Z. I guess something similar could be done for controlling HAWK-800, too. Having all the parameter names shown in human readable format on the LCD would be nice.
