Hello Husc,
Unfortunately time has become very scarce, and I couldn’t find enough to get this Panel done. The D50 has about twice the amount of parameters the D20 has, and needs a very well thought out GUI, which I couldn’t figure out yet.
If you’re interested in building a mockup, with no functions or sysex, I could maybe find the time to implement the functions for the panel.
