A -ton- No hesitation to enthusiastically share that it was actually a parallel goal to see just how deeply I could go while keeping it stable, performant, and extensible for the long term. I ended up building a lot of ancillary agent infrastructure to push the determinism in all the fanned out work slices, too. https://thinkwright.github.io/threadmark/ Also: https://brume.aftertone.co/develop.html#agents

Did you give any thought to using JUCE as a general framework? This way you could add more synths very easily .. (Apologies if you already do, haven't looked for sources yet..)

I wanted another multi-part hardware synth, so I thought it would be fun to see what I could come up with using the parts I already had, particularly the touchscreen. Loosely inspired by Norns, Brume is a four-part multi-timbral synthesizer that runs on a Raspberry Pi Compute Module 5. It has four synth engines and six voices per part, a shared filter section feeding an effects chain, a sandboxed Lua scripting layer,…

I don't know how intentional this was, but it Just Works on macOS. It builds and runs, with UI. I have an OP-1 field attached and it takes the MIDI notes and synthesizes sound. I can't imagine why it wouldn't Just Work with a DAW sending MIDI as well - no need for external hardware, at least on Mac!

Yeah that's by design, and kind of a nifty byproduct. The demo tune on the landing page was actually generated by the DSP engine running on macOS. For me, it's mostly a development aid but you can use it that way if you wanted. Just wasn't part of the motivation. I wasn't looking for another standalone macOS app or VST. Wanted something tactile (controller I already have muscle memory with) and a touchscreen UI.

I certainly don't mean to minimize the work - you've done a fabulous job! I went off to find the hardware to assemble and the prices are kinda nuts... It's awesome having the option to run it on something I already have.
