Still battling away to develop this, keep getting distracted by the rather unfortunate need to work at a real job during the day…
I’m now focussing on getting all the master parameters accessible. The Global Parameter screen is mostly functional now as a display of the current status. I still need to add code to get the parameter values applied back to the underlying objects and to then save this back as a sysex command to the Kurzweil Synth.
