Shoutout to indecisiveeric.com/gesture-synth, which went viral a few weeks ago on Instagram. It allows users to use both hands to perform chords.
gesture.live is an exploration on how to take this gesture synth further. I am using the same chord language, but am compressing it to one hand, so the other hand is free to play melodies, add drum/bass patterns and control effects.
The question that decides this is whether note-ons are quantised. Webcam hand tracking is 30fps on a good day, so there's 30ms of jitter before the audio thread even hears you, and you start feeling timing errors well under that. Snapping to a 16th grid makes it playable but you lose pushing and laying back, which is most of what makes a part sound human. Freeing the second hand by compressing chords into one is the right call either way.

@asadmalik901 I am quantizing the chords to the grid since they also influence the bass and the notes available to play the melody. The melody is completely in realtime! I haven't found latency a big issue so far, but its good to to think about!
the demo video looks great in a well lit room at a desk. has anyone actually tried this on a small stage or at a house party yet? I'm curious how the hand tracking holds up under stage lighting or just dimmer, more colored light than a webcam usually gets pointed at, since that seems like the real test of whether this leaves the bedroom-producer use case.

@galdayan Thanks for the comment! I haven't tested it with a live audience yet. The initial use case was for the bedroom, but would love to optimize for live performance in the future!
@robin_van_soelen makes sense to ship for the use case in front of you first. stage lighting is a solvable problem later, and probably an easier one than the realtime chord tracking you already nailed - worth keeping on the roadmap once the bedroom version has legs.
I am no musician, so probably I will not ever use this, other than to play with my kids, but this seems amazing!
