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.
