Sampler

Sampler

Drop in any audio file and it's pitched across the keyboard around a root note you set — trim the start/end, shape it with attack/release, and choose one-shot or sustained looping.

Load any audio file (wav/mp3/ogg) or record from your microphone — it gets pitched up and down across the keyboard around the root note below.

Mode

Click the keys to audition — pitch stretches up/down from the root note (marked R). One-shot plays the trimmed clip through once; Sustain loops the trimmed region for as long as you hold the key.

Effect

Echo Chamber

A feedback delay with a darkening tone loop, tape-echo style. Pluck the pads and turn the echoes into rhythm.

Hit a pad, then sculpt the echoes — feedback above 70% gets wild.
