A unofficial firmware for Crumar D9U for controlling the drawbars of the Roland FA worktations (FA-06, FA-07, FA-08) tonewheel engine.
This simple sketch is based on the original sketch by Guido Scognamiglio (included in the original documentatio of Crumar D9U) and other snippets that I found on the web.
I never tested it on a real D9U (I don't own one), but happened that Crumar released the D9U at the same time I was working on a similar DIY project: so I had the SysEx code for the FA ready and being a fan of the Crumar and GSI work I put this together in an evening thinking of releasing it in the spirit of Open Source. ...but then... as often happens I never published the script... espacially because I never found time and need to test it. Fast forward to october 2022: a user on The Keyboard Corner forum asked for the script so I taked the plunge and put it here.
I ask you, if you try the sketch, to report issues and feedback here: I'm pretty sure that with a few iteration we can have it working.
