Sweep the room
One knob with a centre detent: a resonant low-pass closes below, a high-pass opens above. BASS KEEP holds the bottom while you take the top off.
The DJ sweep, the three-band kill, the dub echo throw - the moves a selecta makes on a rig, in one box across your group bus.
Perpetual licence · factory bank included · instant download on release · SU activation, up to 2 machines. Licensed under our Software EULA.
Built for the moment the tune needs to move - drop a band, sweep the room, throw the mid into the echo, then bring it all back. Instant, and click-free.

One knob with a centre detent: a resonant low-pass closes below, a high-pass opens above. BASS KEEP holds the bottom while you take the top off.

BASS, MID and TREBLE, each an instant but never clicky cut. HARD is a 24 dB/oct kill, SOFT a gentle thin. Play them like switches.

Capture the mid into the delay and drop it from the mix. SPEED bends the repeats, FEEDBACK holds the wash, HOLD keeps it level - and the sirens send in too.
Drop Sound Boy - Box of Trix across your group and play the moves a selecta plays on a rig - the cut, the sweep, the echo throw - live, in time, and click-free. Then hit KILL and the whole panel snaps back, your EQ left exactly as you dialled it.
Every control earns its place - sweep, three kills, a bass parametric, a dub echo and a tube stage. No 40-page manual, just the moves.


Cut the mid, sweep the room, throw it into the echo - that’s the whole dance in three moves.
