Description
MIX
CC 12
Ratio between dry and wet reverb signal. Fully counter-clockwise is 100% dry, fully clockwise is 100% wet. 50/50 split at roughly 3 o'clock.
LEVEL
CC 13
Overall output level. Unity gain at 12 o'clock (value ~64). Full left kills signal, full right boosts ~6dB.
DWELL
CC 14
Level of dry signal driving the spring tank. Higher values produce thicker, more animated, more overdriven reverb response.
TONE
CC 15
High-frequency damping on the wet signal. Counter-clockwise for darker reverb, clockwise for brighter.
TIME
CC 16
Decay time of the reverb trail. Fully clockwise sets infinite sustain that devolves into self-oscillation.
BASS
CC 17
Low-end frequency level on the wet signal. Counter-clockwise for lighter reverb, clockwise for thicker, bass-heavy sound.
PRE-DELAY
CC 18
Time between the dry signal and the initial reverb reflections. Higher values create a slapback-like separation effect.
DIFFUSION
CC 19
Smooths the spring reverb effect. Higher values produce a smoother, less animated trail that loses some "springy" character.
MOD DEPTH
CC 22
Pitch modulation depth applied to the wet reverb signal. Off at minimum, gradually increasing pitch variation clockwise.
MOD RATE
CC 23
Rate (speed) of the pitch modulation applied to the reverb.
STEREO OFFSET
CC 24
Stereo ping-pong separation for tremolo. Full left for mono, full right for 180-degree stereo ping-pong.

Description
TREM DEPTH
CC 20
Depth of the tremolo effect. Higher values produce more pronounced amplitude modulation.
