Wavefolding is widely used in modular synthesis and experimental music production to add character, aggression, or shimmer to sound sources. Unlike simple hard clipping, which crushes transients, wavefolding preserves amplitude information by folding back on itself.

MAKE MUSIC BY TOUCHING THE MACHINE Tonkro is a playful music workstation for iPad: part synthesizer, sampler, drum machine, sequencer, recorder, editor, mixer, and DJ performance space. SHAPE ORIGINAL INSTRUMENTS Explore distinctive synth and drum engines through four expressive controls. Each workshop is built to feel immediate: touch the illustrated machinery, hear the result, and let the characters react to your performance. SAMPLE THE WORLD Record through the microphone or import audio. Play one sound chromatically, divide it into untransposed slices, or map multiple samples across keys and pads. Trim, crop, loop, reverse, fade, change speed, transpose, and preserve the original recording with non-destructive editing. FIND RHYTHMS YOUR WAY Seven sequencer personalities turn taps, held notes, patterns, gestures, and playful systems into musical motion. Tempo, transport, MIDI, and recording stay connected, so a sketch can become an arrangement without breaking the flow. RECORD AND ARRANGE Build with eight stereo tracks. Record audio or notes, edit clips and piano-roll performances, overdub, punch, loop, lift, drop, mix, export stems, and save portable project bundles. PERFORM WITH MONSTER DECKS Load two tracks, set beat grids, sync, use key lock, cue points, hot cues, quantized loops, EQ, filters, pitch bend, and the crossfader. Record the performance or print it directly into the tape arrangement. MADE FOR PLAY Tonkro keeps its creative tools visible, touchable, and full of character. It works without an account, advertising, or third-party analytics. Your projects, recordings, and imported samples remain on your iPad unless you choose to export or share them.
