Luppolo

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:

• Up to 12 tracks, each shown as a circle that fills up as it plays
• A sample-accurate master clock so every track's loop phase-locks to the others automatically
• Quantized, count-in recording with a live "starts in N beats" countdown
• Configurable tempo, time signature, and track count
• Per-track volume, mute, and single-level undo
• A metronome with selectable beat/accent sounds, including your own custom samples
• Session save/load and mixdown export to WAV or FLAC

Luppolo uses JACK (via PipeWire's JACK compatibility layer) for audio I/O, and connects to your audio interface automatically on launch.
