Luppolo is a real-time, multi-track audio looper for guitar (or any instrument), in the style
of Loopy HD — record a phrase, loop it, and keep layering more tracks on top while the first one
keeps playing.

Features:
<ul><li>Up to 12 tracks, each shown as a circle that fills up as it plays</li><li>A sample-accurate master clock so every track's loop phase-locks to the others automatically</li><li>Quantized, count-in recording with a live "starts in N beats" countdown</li><li>Configurable tempo, time signature, and track count</li><li>Per-track volume, mute, and single-level undo</li><li>A metronome with selectable beat/accent sounds, including your own custom samples</li><li>Session save/load and mixdown export to WAV or FLAC</li></ul>
Luppolo uses JACK (via PipeWire's JACK compatibility layer) for audio I/O, and connects to your
audio interface automatically on launch.
