TouchOSC controlling TR-6/8S via SysEx

Hello!

I found a fantastic tr8s manual for midi and sysex showing how the TR editor is controlling the TR machines: https://mididesigner.com/qa/10040/roland-tr-8s-sysex-whats-what

There is a guy that is making a control surface in Midi Designer but this software looks sketchy AF, constant popups, convoluted payment system, and ad trackers for everything. I’d rather use something more mature like TouchOSC, and I have some questions:

Can you control a device via sysex? So taking the manual I could do my own version of the iPad controller for the Roland drum machine?

Is there coding involved? If yes, did anyone vibe code in TouchOSC? Is it needed or is it simple stuff?

And lastly are there people who do this for a living and could do a controller like that if commissioned to?

Thanks!

    The hard part is understanding sysex. Making TouchOSC controls send and receive sysex is easy. Doing other things such as changing labels based on received sysex requires scripting. TouchOSC uses LUA for scripting. Lua isn't particularly hard to learn.

    What I'm not sure about is doing things like saving control sets to files. I assume you'll need to do that to do things like save and recall settings.

    I'd start simple. Just put up a knob and get it to send Sysex to the TR to adjust a control. Then see if you can get bi-directional feedback going. Then I'd look into Lua and see if I could figure out how to save and recall that knob "preset". Then build from there.

    The sysex concepts in Midi Designer Pro 2 are similar to TouchOSC, so that manual will probably help you a lot. I made a ES-1 controller with Midi Designer Pro 2. Once I could make (some) sense of the ES-1 midi implementation chart, I was able to control it bi-directionally. That was about 1/5 of the total sysex implementation. I couldn't make heads or tails of things like sysex dumps.

    Good luck. 👍🏼
