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 […]

A 14HP Eurorack replica of the ARP 1042 module which has three voltage controlled amplifiers. The original was announced by Tonus/ARP back in 1970 but unfortunately never made it into production or a prototype stage. It would have provided a set of VCA’s to be used for CV and signal control with having to tie […]

This 20HP module expands the capability of the Behringer 1027 sequencer by adding two additional columns of variable control voltages. The module connects to the B1027 with an included 12-way ribbon cable. The module can also be used stand alone as a source of preset voltages with manual or gated selection. The eight steps of […]

The 12HP wide AM1005 is a re-imaging of the four quadrant multiplier and VCA that ARP launched as the 1005 module in 1970, and was included in the 2500 synthesizer. The electronic design is close to the original, with CV inputs and level potentiometers for the VCA, and audio inputs going straight into the four […]

This 4HP module expands the capability of the Behringer 1027 Sequencer by adding a three channel Sequential Switch, that can generate sequences of 8, 16 or 24 steps. Whilst the Behringer 1050 can be used for the same purpose, it is a waste of a wide and feature rich module, that can be better deployed […]

This 14HP module is a re-imagining of the ARP 1013 octave filter bank that was announced in 1970 by Tonus as part of the 2500 Synthesizer but it never made it into production. It consists of eight band pass filters with their cutoff frequency spaced one octave apart, from 63Hz to 8 KHz. The filter […]

The 12HP wide AM1006 is a re-imaging of the first filter that ARP launched in 1970 as part of the 2500 synthesizer – the 1006 module. Why do this again? The aim of the 2025 Edition is to get as close to the original sound and user interface as possible, in Eurorack. I don’t expect […]

This 8HP module expands the capability of the Behringer 1004 VCO by adding the waveform mixer from the original ARP 1004P. The module delivers all five waveforms independently, as well as mixing them into a single output. Description The AM1004P module enables the Behringer 1004 module to be transformed from a T (toggle) version into a […]

An 8HP wide Eurorack module that adds an extra column of eight control voltages to the Behringer 1027 Sequencer. There are outputs for both 2V and 10V ranges and green LED’s indicate the step position. The module is connected internally to the Behringer 1027 using a 12-way IDC ribbon cable. There are eight rotary potentiometers […]
