Pumpit Raw

Glue your kick and sub together with a single knob. Pumpit Raw is the free, one-knob version of Pumpit: turn up GLUE and a tempo-synced sidechain pump locks your low end into that punchy, breathing groove on any track. No routing, no sidechain input, no setup: it reads your DAW's tempo automatically, and the output is auto-leveled so the pump adds groove, not volume swings.

Tempo-synced pump engine: the duck envelope is driven by the host transport's PPQ position, locked to a 1/4-note cycle, with an internal clock and a 128 BPM fallback so the pump keeps running even when the transport is stopped.

Envelope shaping: a per-cycle envelope combines the hard-wired Hold with the Punchy curve, applied as a smoothed 2 ms duck gain to eliminate zipper noise, and resets cleanly on transport jumps and tempo changes.

Lookahead, constant latency: the main audio is delayed by a fixed 5 ms so the duck is applied cleanly ahead of the beat, and that latency is reported statically so the host's plugin delay compensation stays stable mid-stream.

Level-matched output: auto-gain is forced on and the output biases down slightly at full, so the pump adds groove, not volume swings, while a tanh soft-clipper holds a 0 dBFS safety ceiling.

One macro, hidden parameters: GLUE is the only automatable parameter; every other engine control is non-automatable but still saved and restored with the session, with NaN/Inf protection and ScopedNoDenormals guarding the whole block.
