Tape & texture machine

Loops, grains.
Imperfect repetition.

A four-track instrument for ideas
that refuse to stay still.

Built for touch. Open to chance.

01 / The instrument

Record it. Break it.
Let it become
something else.

Somewhere between tape, sampler and granular instrument. Four tracks to catch a sound, wear it down, and find what lives underneath.

RUN4 Tape on iPad, with waveform, tape controls and the Master dock.
The same Tape workspace arranged for iPhone.
The same world. Two ways in.

02 / Four tracks

One good accident.
Four ways to follow it.

RUN4 Tape: capture and reshape recorded sound.

01 / CAPTURE — Record, loop, overdub. Remember the last few seconds.

03 / Poly & movement

Loops don’t have
to repeat
themselves.

A sample becomes a voice. A chord becomes a pattern. Nudge the pitch, move the steps, let chance into the loop.
