LFOs

VXN1 carries two LFOs with deliberately different scopes:

• LFO 1 is per-voice. Each voice owns a phase; default behaviour retriggers on note-on. Has delay / fade-in for ease-in vibrato.
• LFO 2 is global. One phase shared across every voice in both layers. Useful when you want the whole instrument moving together — wobble basses, dual-osc detune drift, synchronised filter cycling.

Waveforms

Both LFOs share the same six shapes:

Rate and sync

Rate (0.01–40 Hz, exponential taper centred at 5 Hz) is free-running by default.

Sync locks the LFO rate to host tempo. With sync on, the rate knob steps through beat subdivisions instead of Hertz (1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/8T, 1/16T, …). The control-rate update cadence is unchanged.

LFO 1 specifics

Free-Run (off by default) controls phase retriggering:

• Off — phase resets to 0 on every note-on. Predictable vibrato that always starts from zero.
• On — phase runs continuously across notes. Better for chord-spanning LFO sweeps where you don’t want every voice’s phase coupled to its note-on time.

Delay Time (0–4 s) sets a hold before the LFO becomes audible after note-on. Useful for slow-onset vibrato that only kicks in once the note has been held.

Fade (0–4 s) is the ramp-up time once the delay expires — the LFO’s output amplitude crossfades from 0 to its target over this interval. Combined with Delay Time, this gives the classic “vibrato that grows” voice mannerism.

Delay and Fade are clocked from note-on. With Free-Run on they have no per-note anchor and are effectively bypassed for held notes — use Free-Run off if you want the delay/fade behaviour to be predictable.

LFO 2 specifics

LFO 2 has just Shape / Rate / Sync. There’s no delay or fade because the global LFO has no per-note event to trigger from. (It also has no Free-Run option because it’s always free-running — that’s what global means.)

Where the LFOs go

Both LFOs are sources on every modulation panel:

• Pitch — vibrato (±12 st).
• PWM — pulse-width wobble.
• Filter Cutoff — filter sweeps. (LFO 1 and LFO 2 each have their own fixed depth knob.)
• Amp — tremolo.
