## What is RUN4?

RUN4 is a four-track Tape & Texture Machine for iPhone and iPad. Capture sound, turn it into moving tape loops, build patterns and instruments, then shape everything into a playable performance.

THREE MATERIAL MODES

• Tape — record, overdub, loop, freeze and recall sound. Listen/Capture can turn the last seconds of RUN4’s internal mix into new material.

• Poly — play samples, classic synth and 4-operator FM voices, hosted AUv3 instruments and step patterns.

• Disc — stream and perform long-form audio.

SEQUENCE

Build patterns with up to 64 steps, Euclidean tools, step locks, probability, variation, randomization and count-in.

SHAPE EVERY TRACK

Move through Grain, Tone, Color and Air. Use device presets, the modulation matrix and four send busses, then finish your mix inside RUN4 with Tone, Drive, Glue, OTT, Width and Limiter.

Export final mixes or individual WAV stems.

BUILT TO PERFORM

Switch sets, control macros and punch-in effects, run audio-reactive visuals, sync via MIDI Clock or Ableton Link, and map external MIDI controls.

Dark or light appearance. Same instrument.

AUv3 + PROJECT WORKFLOW

Host compatible AUv3 instruments and effects inside RUN4, or load RUN4 as an AUv3 effect, source or instrument in a compatible host.

Save projects locally or sync them through iCloud between iPhone and iPad. Third-party AUv3 plugins must be installed on every device used to open a project.

Also includes Bluetooth MIDI, CC Learn, AudioShare import, offline bounce and a searchable in-app manual.

TÓLF — TWELVE MORE TRACKS

TÓLF is an optional one-time in-app purchase that adds 12 additional tracks to RUN4’s four-track workflow.

• 12 additional tracks with sampler, synth and granular voices.
• Four pattern generators — Euclid, Walk, Cascade and Bloom.
• Record TÓLF tracks or groups directly into RUN4’s Tape tracks.
• Export TÓLF stems and MIDI.

TÓLF can be unlocked from Settings and restored on any device using the same App Store account.
