The current version of my version of the MKS70/JX10 panel can be found here
Several things still need to be done on the panel, namely:
a GUI for the enveloppes
making the dropdown menus work (selecting waveforms and ranges don’t work at the moment because of what i suspect is a ctrlr bug)
overall layout design
I am currently stuck with the parameters still not updating until moving the alpha dial, despite showing the correct value on the synth.
I tried applying and not applying the Roland checksum, and looked everywhere I could to find a global parameter to reduce the Sysex transmission speed.
Instead of duplicating the PG800 layout, the idea is to offer a design that allows for an overview of both tones, as well as a new part that will allow for controls of both tones parameters at once.
I hope this will be of interest to someone 🙂
