PolySampler
VST3/CLAP plugin that auto-multisamples a MIDI instrument and exports OP-XY presets

Works with
- A VST3 or CLAP host
- A MIDI-controllable instrument to sample
Good to know
- Heads up: Early and experimental, tested only on macOS (Apple Silicon); the author says to expect rough edges.
About
PolySampler is a VST3/CLAP plugin that multisamples a MIDI-controllable instrument automatically. You hit Start and it steps through every note in your range, recording, trimming silence, finding loop points and packaging the result as a drag-and-drop .preset file for the OP-XY.
