Atmosynths concept for #atproto spaces is ready: Users will be able to start bands (at.atmosynth.band) with them as band leader (space owner) and optionally some more band members. And everyone gets a sketchbook space (at.atmosynth.sketchbook) in which they can store content only visible to them.

In observance of Zinetober, a brief homage to the blues. It was a blast making these Web Tile synth patches with atmosynth.at by @center.for.cybernetic.beauty. Drums, bass, organ, and a spinning Leslie, one page at a time. Playing on appmosphe.re by @robin.berjon.com.

atmosynth.at now shows a lineage tree when forking or importing other people's patches, modules or samples. Nothing here is cryptographically proven, as people could also just copy & paste open data, but it is a nice built-in way to pay tribute.
Screenshot of atmosynth showing the lineage tree of a patch: A patch by user A is forked from another user's patch, and both patches use Atmosynth built-in modules.

From my experience, SDD's viability falls as the share of bottom-up knowledge in a system increases. SDD is great for the green-field CRUD demo, it's bad for byte-level VST plugin wrangling where most knowledge about the system's desired behavior is learned while debugging.

There is already the Noise module which you are using in your patch. I have renamed it to "White Noise" because this is what it is. Is there anything else you need?

Thank you for the valuable feedback. I have published new versions of all oscillators with four octave (4800 cents) detune ranges. Your patch still pins the old versions, so it sounds the same. When you add new oscillators, the versions will be used.

MPE should work but I have no MPE controller to test with. But if you create an Expression module (per note) and route it to (per note) effect modules, one effect chain per note should created with independent pressure/slide/bend parameters. Would be great if you could try it out and give feedback.
