This 14 HP wide module contains two identical voltage controlled ADSR envelope generators, with curve select, mode select and variable timing. Each stage of the ADSR, including timing, can be controlled by an external +10V control voltage. The curve can be selected from exponential or linear, and the mode of the ADSR can be selected […]

This is a replication of the 1046 Quad Envelope Generator from the 1970 ARP 2500. This module was one of the last modules to make it into production, and it proved very popular as it combines two 1003’s and two 1033’s in one 2 unit width panel. AM1046 Module The AMSynths design contains the original […]

The 12HP wide AM1008 is a completely new module that marries a VCA and ADSR envelope generator in the style of ARP 2500 dual modules (e.g. Filt Amp, Mod Amp). The design makes use of 1980’s synth chips to create a simple but elegant design that works well with the AMSynths range of 2500 style […]

This module is a replica of the Roland 100M 141 which appeared in 1978 as an initial prototype. It never made it into production and the Gate Delay reappeared in the later 1983 172 module. The Roland 141 came to light in late 2022 thanks to Alex Ball buying one! He has taken photos of […]

Overview In 2022 I developed a set of Eurorack modules to replicate the Roland SH-101, which was originally launched in 1982. The AM8112 module is an accurate replica of the ADSR and VCA circuits in the SH-101, made possible by the release of the AS662 chip by Alfa Rpar. It is very similar to the […]

A 10HP wide module that replicates the VCA and envelope generator from the Roland SH-2 monosynth. Overview In 2022 I developed a set of Eurorack modules to replicate the Roland SH-2, which was originally launched in 1979. A fantastic sounding two VCO analog monster. The AM8103 module is an accurate replica of the ADSR and […]
Continue ReadingThis module is a simple transistor based design with the traditional 4 stages but with Sustain and Release pots reversed in panel location. The module uses the Moog S-trigger standard rather than the familiar Euro Rack gate signal (or V-trigger), with a S-trigger being a momentary connection to ground. Once ground is released the envelope […]
