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.


02 / Four tracks
One good accident.
Four ways to follow it.

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.
Meet Poly in the manual ↗
04 / Optional expansion
TÓLF
Twelve more places
for sound to go.
A twelve-track sequencer inside RUN4. Synth, Sampler and Granular. Generators, Arp and Strum. Find a phrase, build a song, send it back to tape.
