A harmonic loudness and presence enhancer. Instead of just turning things up, Puush lifts the quieter detail and adds smooth saturation, so more of the sound sits forward and loud while the peaks stay where they were. Gentle for glue and density, hard for an obvious but still musical slam.

HEAT draws the output spectrum and lights it up wherever Puush is adding harmonics: red for the odd harmonics from the saturator, and the WARMTH colour for the even ones. The ODD and EVEN chips show each in dB, SENS sets how easily it glows, FREEZE holds it still, and the meter on the right shows the loudness you have gained.

WARMTH runs on SILK, which blooms on the loud moments and eases back as things quieten, or IRON, which holds the same colour at any level so fades and tails stay rich. Switch to MID/SIDE and the SIDE fader pushes the stereo edges on their own, with MID GAIN and SIDE GAIN to rebalance. Shown here in the Light skin.

Press AUTO GAIN and Puush listens, then sets OUTPUT so it comes back to the level it went in at, by peak or by loudness. In MID/SIDE mode it matches the centre and the sides separately, using OUTPUT for the centre and SIDE GAIN for the sides. Once it is done it steps aside, and lights up again when you change something.
DELTA plays just the harmonics Puush is adding. MONO checks the fold-down, SIDE solos the stereo sides (it works in BYPASS too), and every fader has its own bypass.
Start from 78 factory presets across Master, Mix Bus, Drums, Bass, Vocal, Guitar, Synth, Heavy and Character, save your own, flip between A and B, and pick the Light or Dead Quiet skin.
| Feature | What it does |
|---|---|
| Harmonic saturator | Smooth odd harmonics (3rd, 5th, 7th), driven by INPUT, set with EFFECT and shaped with EDGE. |
| WARMTH | 2nd and 4th harmonics from the centre, on the SILK or IRON circuit. |
| PUSH | x1 or x2 drive into the saturator. |
| MID / SIDE | Process the centre and the sides apart, with a SIDE fader plus MID GAIN and SIDE GAIN. |
| AUTO GAIN | One-click match by peak or loudness, centre and sides separately in MID/SIDE mode. |
| HEAT display | A live spectrum that glows where harmonics are added, with ODD and EVEN readouts, SENS and FREEZE. |
| Monitoring | BYPASS, DELTA, MONO and SIDE, plus a bypass on every fader. |
| CLIP | A true 0 dBFS ceiling at the very end of the chain. |
| HQ | 1x to 8x oversampling for cleaner highs. |
| Meters | Loudness added, plus IN and OUT meters in L/R or M/S. |
