Samplab

Samplab let producers edit the notes inside a polyphonic sample, much like MIDI, by transcribing audio and resynthesizing the changes, and it became a popular free audio-to-MIDI tool. The company is winding down: it stopped supporting its online platform on September 17, 2026, refunded yearly subscriptions past that date, and offered final offline versions of Samplab and its Resynthesizer so existing users can keep working. It's listed here for reference; newer options like RipX DAW cover similar ground.
