Capabilities 2

Spring Reverbspring-reverb
Drives an external spring reverb tank with two VCA-controlled inputs (different routing), CV-controllable dry/wet mix, high-pass filter on tank input, and MIX/WET outputs.617
Voltage-Controlled Amplifiervca
Two independent input VCAs (one per input) with CV control and slider attenuation.617

Jacks 7 — 5 in / 2 out

NameSignalVoltageDescription
Inputs (5)
IN1audioAudio input 1; signal is sent both to the mix output and the reverb tank. Amount sent to tank is controlled by Slider_IN1.617
IN1 CVcvCV control for the VCA at input 1.617
IN2audioAudio input 2; signal is sent straight to the reverb tank. Amount sent is controlled by Slider_IN2.617
IN2 CVcvCV control for the VCA at input 2.617
MIX CVcvCV control for the DRY/WET pot.617
Outputs (2)
MIXaudioAudio output of the mix (IN1 + reverb tank output).617
WETaudioWet output — direct output from the reverb tank only.617

Parameters 5

NameTypeRangeBehavior
HPFknobControls the cutoff frequency of a high-pass filter on the signal going to the tank. At minimum there is no filtering. Its purpose is to avoid saturating the tank with low frequencies.617
MIXknobControls the dry/wet balance of the MIX output. CV control is available via MIX CV input.617
PEAK METERmenu_settingLED meter showing the amount of signal fed to the tank. Green = optimum level, orange = high amplitude, red = saturation.617
Slider_IN1faderVCA level of IN1. Controls the amount of signal sent to the tank. When a CV is present at IN1_CV this slider acts as an attenuator of that signal.617
Slider_IN2faderVCA level of IN2. Controls the amount of signal sent to the tank. When a CV is present at IN2_CV this slider acts as an attenuator of that signal.617
