Three years in the making. Midicircuit is coming to Android and we're opening beta access now. If you've been waiting to bring your MIDI workflow off iOS, this is your moment. Spots are limited.
What if fenced code blocks could play music? We built an open-source toolkit that turns markdown into interactive instruments: drum pads, keyboards and sequencers, all running in the browser.

A live session showing what Midicircuit can do in practice: Playgrounds, Circuits and the whole workflow from scratch.

Not all samples are created equal. The ones people actually come back to have six things in common: punch (crisp transients), body (no thin or hollow sounds), character (a distinctive identity), consistency (everything belongs together), dynamics (responds well to velocity), and a clean tail. No clicks, pops, or abrupt cuts.
Quick test: load each sample, play it at velocity 30 and then 127. If there's no personality difference, your dynamics need work. The best packs feel alive at every velocity.
Our other app. If you don't know it yet, it's been quietly doing its thing. Worth a look.

Still a few left in the shop. Délcio designed them, we hand-assembled the packaging in Tilburg. Real ones only.
