performance - a new live-coding language for MIDI

5 Upvotes

Hi everybody! I've been working on a little MIDI language I call "performance". Think of it as algorave software for MIDI instruments. It works with your DAW or your physical synthesizers. Anything that speaks MIDI. The repo in bitbucket contains everything you need to get started.
It's by no means done, but I'd love to hear what you think about it. =)

Hello all this is an original shematic i have made it does 3 different things just on how you patch it, i can get less q but not more. i tried adding a non inverting amp between the cap going from in_ to in+ also a inverting one and its the same. the only method i have found is adding a 100nf cap from in+ to a 10k pot and then connect it to the output (this has to be done with a trim pot)

A round-robin soft synth inspired by the Vermona Perfourmer.

I'm making my first synth (software) design, and it's heavily inspired by the Vermona Perfourmer, a synth I had to sell during college because I simply couldn't afford to keep it. It's still the piece of gear I regret selling the most.

Concept:

Carousel is a five-voice round-robin polyphonic synthesizer built around a simple idea: a circle. Its five voices sit like seats on a carousel, and every note you play is assigned to a different one - in sequence, random, or all at once.

Each voice is a complete synth with its own oscillator, filter, and envelopes. Differences in tuning and timbre drift across the stereo field, creating a sound that is organic and quietly imperfect - like an old carousel left in the sun.

Carousel is designed to be simple. No LFOs, no presets, no complex synthesis - just pure play. A childhood that exists only in memory.

Disclaimer: I did get help from Claude with the coding. The idea for this design had been in my head for a long time, but my coding skills were sooo limited (in fact, I had virtually none). As more of a visual/UI design hobbyist than a programmer, I was finally able to bring this idea to life.

LM13700 based VCF pops and distortion issue.

Dear lovely Community ♥,

I finished building my modified version of the Skull and Circuits VCF-3. I say it is a mod, but honestly I changed so much stuff that it might as well be its own thing.

Anyway, I have this issue where the output pops and scratches when there is an input, the cutoff is low and the resonance is turned past 50%.

Please take a look at this video, do you guys know what could be the issue here?
