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

The call

DrumComputer's advantage is update cadence (every 3 weeks vs every 7 months) and ratings volume (621 vs 2). On price, ads and device support there is nothing between them.
