Reverb Server

Reverb server: main parameter page.
The bus's reverb engine, hosted on track 5's FX2 (locked; the FX2 chooser cannot change it). An eight-line reverb with ROOM, PLATE and BIG modes, modulated taps, a shimmer, a gate and mid/side width. Every track's REV send, plus the delay's repeats through its DLY knob, feeds it; its tail comes out on track 5 under that track's dry.
Access
Track 5's FX2 page draws only DEL and REV. Every other knob is in the TEMPO window: press [TEMPO], then LEFT / RIGHT to focus the REVERB box.
Adjust the Sound
- DEL on track 5 sends track 5's own dry into the delay; REV sends it into the reverb.
- Tails: ROOM 0.87–3.9 s, PLATE 0.9–4.4 s, BIG 1.6–11.7 s across TIME 0–127.
- TONE is LO and HI on one knob: 0–64 = low-pass, 64–127 = high-pass, 64 flat.
- SHMR is the shimmer amount; SHFT its interval (-12, +5, +7, +12, +19, +24).
- GATE: 0 off; above 0 the wet shuts 52 ms (GATE 1) to 784 ms (GATE 127) after the tank input falls quiet — the 1980s gated-reverb cut.
- DLY is the delay's repeats into the reverb: 0 puts the two engines in parallel, up feeds more of the delay into the tail.
