Midi-Morf is a four-track groovebox for your phone. Build a beat, chop a break, sample your voice and play it all live, with no extra gear. REMIX GRID Load any loop and it splits into 16 pads, locked to the tempo. Tap a pad to jump there, hold two to loop between them, and play rows against each other. Each row can LOOP, play a single SLICE, or GATE while you hold. Record your moves with two pattern recorders, store whole setups in recall slots, and everything stays on the beat. SAMPLER Record from the mic or load your own WAV files. Play a sample across the keys, as one-shots, or chopped into slices. Say "macaroni and cheese" into it and turn it into a beat. DRUMS A synthesized drum machine with kits from 808 and Boom Bap to Jungle, House, Trap, Lo-fi, Disco and Techno, played from a step grid with swing. SYNTH A wavetable synth with a library of presets — basses, keys, pads and leads — and deep editing when you want it. FOUR TRACKS, EIGHT SCENES Give each track an instrument and a sound. Launch clips and scenes in time, mix with volume, inserts and delay/reverb sends, and record what you play. PLAY IT YOUR WAY Step sequencer, a break slicer, a piano roll and drum editor, plus the original Midi-Morf controllers: Morf-Chord, Rose-Chord, Strum-Chord, Morf-Pad and Dual M-Pad. Tilt the phone to move the sound. PERFORM Punch in master FX live: filter, stutter, tape stop, delay throw, reverb wash, bitcrush, trance gate and vinyl brake.
