The NuPump panel: a scrolling waveform with an orange pump lane under it, a live one-beat shape with a dot riding it, and eight knobs below. — NuPump v0.1.0. The orange lane is every dip, in time with your song.

Hear it

A chillwave loop at 100 BPM, dry, then through NuPump on Classic Pump at 1/4. Level-matched. Measured: the mix dips 10 dB on every beat and is back up in about 0.4 s.

Why pump at all

Stack a pad, a bass and a kick and they all fight for the same moment. Everything sits at one level and the groove goes flat.

Duck everything else on the beat and the kick punches through, then the rest swells back in behind it. That swell is the movement all over house, future bass and pop. NuPump draws that shape for you, on the grid, without routing a single sidechain.

What you get

Locked to your song. SYNC follows your DAW's tempo and bar position, from 1/16 up to a full bar, dotted 1/8 included.
Or follow your real kick. SIDECHAIN restarts the shape on every hit from your kick track, with a threshold so only the kick triggers it.
Four shapes. Pump, Duck, Gate and Sine, plus ATTACK, LENGTH and CURVE to dial the swell exactly.
See every dip. A scrolling scope with the pump lane under it, and a live shape with a dot riding it.
12 presets. From Classic Pump and Future Bass Breath to Trance Gate 1/16 and a Metalcore Breakdown Pump.
Blend it. MIX for parallel pumping, NUDGE to push the dip off the grid.
Measured, not guessed. Every build is checked: dips land within 0.63 ms of the beat and within 0.15 dB of the depth you set, with no clicks.
