Add creative fills and variations to your loop to keep it constantly moving with fresh ideas - great for jamming or to prevent audio stagnation. ••• Wavetable/Resynth Import & Sampler ••• Import your own audiofiles to create Wavetables. Resynthesize Hihats, Snares, even Chords with the Resynth import feature or switch to Sampler mode to play back samples the ordinary way.

Verdict
