Analogue Systems RS-310 Reverb/Chorus (Dual Bus)

RS-310 is a Reverb/Chorus module with voltage control of dry / wet mix and the delay time. You can create flanger and chorus effects but also short echos and reverbs.
Thanks to a new dual-bus concept, this circuit is fully compatible to Doepfer’s Eurorack standard.

The module is based on a bucket brigade device with six parallel delay taps. Those six delay times have no relationship to each other and their outputs have different levels. You have to consider the chorus/reverb effect as a mixture of six different short delays what results in a dense sound. The clock frequency which scans the bucket brigade is audible and you´ll have to use a low pass filter in order to eliminate or minimize it.

The delay time can be set with the according control between 2.5ms and 150ms. CV control gives you much shorter / longer delay times.

The resonance has to be considered as the delay´s feedback parameter and it can go up to self-oscillation. The dry / wet relation can be controlled manually and with a CV.
