Description This module is inspired by the 173 module in the original 100M. There are the same four signal gates, now transformed into a sequential switch. Each gate can be: ON, a preview mode Controlled by the gate inputs Controlled by the sequential clock The frequency of the internal clock...

Description This module is an accurate replica of the original Roland module, with all the features retained including MPX control of a second portamento timing and voltage control of portamento time The amount of portamento applied to the signal input is set by the sum of the...

Description This module is a replica of the Roland 141 prototype of 1978. It contains an ADSR envelope generator, a Gate Delay and an Inverter Adder. The envelope generator has been carefully translated to Eurorack; with the correct attack curve, 2Meg log slide potentiometers and the...

Description This module is a replica of the System 700 Dual ADSR from 1976. The circuit uses a unijunction transistor to provide fast envelopes and both Gate and Trigger inputs. The envelope shapes have been accurately translated into Eurorack, along with the dual timing feature (x1.0 and...
