PX-TOM Fusion Dynamics
Round, Tight, Alive.
PX Series · Fusion Dynamics · SOUNDLOCK™ · VST3 · AU
PX-TOM is the tom module of the PX Series — Fusion Dynamics: five style recipes (ROCK · METAL · POP · FUNK · JAZZ) drive a 4-band smart EQ (PUNCH), a transient forward/back control (DEPTH) and a dynamics-following two-band HARMONIZER (BODY/GLOW). The module LEARNS the drum — SOUNDLOCK™: a passive detector fingerprints the fundamental, ring, attack and decay, and where the module carries dynamics they set their own thresholds. This module: window-keyed AUTO GATE (the trigger listens only at 120–400 Hz). The knob rings glow with what the engine is actually doing — a hit is an event on the face, not a change of shade.

Header & style
2
STYLE — Five locked recipes: they set the EQ band targets, the harmonizer bands and character, and — where present — the dynamics times. Pick the show’s style; the knobs scale the recipe, they never replace it.
Main knobs
3
PUNCH — 0–100: how far the style’s 4-band smart EQ travels from its starting values toward its maxima. 0 is not off — it is the recipe’s starting point.
4
DEPTH — ±50, FORWARD/BACK: transient stance. FORWARD hardens the attack and brings the drum to the front; BACK softens and seats it. Default 0 everywhere — by decision.
HARMONIZER BOOST
5
BODY — 0–100 (ember): harmonization of the low region — warmth under the fundamental. Inverse-dynamic: it fills as the hit rings down instead of stacking on the attack.
6
GLOW — 0–100 (ice): harmonization of the attack/air region. Direct-dynamic: it rides the hit. BODY and GLOW are harmonics, not EQ — they add content, they do not boost what is already there.
7
CLEAN / DIRTY — Harmonic family: CLEAN = even harmonics (default), DIRTY = odd. The source band and character follow the style.
8
HARM SOLO — Hear exactly what the harmonizer is adding — nothing else. The honest way to set BODY/GLOW.
AUTO GATE
9
ON / OFF — AUTO GATE has no threshold knob anywhere: the engine learns the leak edge and sets its own threshold, range and key band; attack/release come from the style. ON/OFF is a soft bypass — safe to hit mid-show. Until it has learned it stays open (FAIL-SAFE). TOM/FL TOM extra: both trigger paths listen only inside a 120–400 Hz window — snare ring/crack sits above it, cymbals far above; neither can open the channel.
10
RELEARN — Re-measures the drum and the leak, atomically. Use it after a mic or drum has moved.
11
GR — Gain-reduction meter, 0…−70 dB — fills as the channel closes.
12
STATE — State line: LEARNING (still listening), BYPASSED, or LOCKED · GR with the current reduction.
13
DIAG — What the learner decided: the branch (leak cluster / quiet channel / single spread), the key frequency it watches, and how much separation room it has. “no separation — staying out” means it refuses to gate rather than eat hits — missing a hit is forbidden, a false opening is secondary.
Output & footer
14
TRIM — Output trim, ±12 dB — keep the module honest in the chain.
15
CHAIN PEAK — Chain peak: the module’s output headroom readout. If PUNCH/BODY/GLOW bought you level, give it back here.
16
FINGERPRINT — The learned fingerprint of this drum: F0, RING, ATK (spectral centroid) and DECAY. Dashes until the listener is READY.
Quick start
- Pick the STYLE — it is the recipe, everything else scales it.
- PUNCH to taste (40–60 is the working zone); DEPTH forward for attack, back to seat the drum.
- BODY/GLOW around 30 and judge with HARM SOLO; CLEAN unless the show wants DIRTY.
- Play the drum and let the gate learn; read the DIAG line, RELEARN after any mic move.
- Watch chain peak; give back with TRIM whatever the processing bought.
