Befaco SPRING REVERB Eurorack Module

via Befaco

Available assembled or as a DIY kit.

"It´s been alwas discussed if electronic generated sound is less “realistic” than the acoustic generated sound. One of the main differneces is the natural inclussion of the acoustic space where an acoustic instrument is played in opposition of electronic generatd ones.A good technique to aproach both worlds is to simulate the acoustic feeling of a closed space.

The reverberation (effect produced by the space where the sounding object is) is the sum of all sound reflexions of a single sound, that reaches a point in differnet moments.

To simulate this effect we pass the sound thru a spring via two transcievers (one in each end). The sound will propagate and, thanks to the contraction and expansion capabilities of the spring, a series of reflexions will be generated. These are very similar to the ones that are generated in an acoustic space.

This module main features:

Two audio inputs. Both CVcontrolled plus slider control.
“IN1″ is routed both to “DRY” mix and reverb tank input.
“IN2″ Goes only to the reverb tank.
Two outputs
“WET” comes stright from reverb tank.
“MIX” is the mix of DRY signal and the outpur of reverb tank. It has CV control

This configuration allows to feedback “WET” signal back to the module via “IN2″ either a stright feedback of passing thru other modules before coming back to IN2.

Like this, with MIX control we never loose our original signal, controlling the ammount of reverber and feedback on the mix.

It features a high pass filter at the input of the tank to control the tone of the reverberations and an eventual saturation of the spring when we are doing a feedback.
There is a built-in vumeter at “WET” output to visualize level and eventual saturation of the signal."
