This 4HP module expands the capability of the Behringer 1027 Sequencer by adding a Sequential Switch that enables sequences of 8, 16 or 24 steps to be generated. The avoids having to use the 1050 module for the same function.

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 8kHz. The filter is very useful for creating formant and vowel sounds. The individual outputs enable voltage control of the filter by using eight external VCA's - for example the 1032 Mixer & Distributor module.

The AM1035 is a 14HP module that re-imagines a "lost" ARP module of the 2500 modular synthesizer. Prototypes of the original appeared in 1970 but the module never made it into production. The AMSynths module fills in a gap of synthesizer history for Eurorack. The module has three discrete four quadrant modulators that provide ring modulation, mixing and VCA capabilities.

This 8HP module expands the capability of the Behringer 1027 sequencer by adding an additional column of variable control voltages. The module connects to the B1027 with an included 12 way ribbon cable. The eight steps of the 1027 are mirrored in the 1028 with three precision control voltage outputs; one at 2V for controlling VCO's and two at 10V for controlling filters, amplifiers and VC env gens.

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.

In 1970 Tonus envisaged the ARP 2500 synthesizer with a massive 25 different modules. This video uncovers the missing modules that never made it into production, with only the occasional prototype surfacing over 50 year ago. AMSynths have re-imagined six of these modules for launch in 2024. They can be used to expand the B2500 eco-system or within any Eurorack setup, to create new and interesting sounds. Enjoy the video!

We are proud to announce the launch and availability of the third SN-101 Euro Rack module, the AM8110 VCO.

The SH02 Project at AMSynths continues after the AM8102 VCF, with the launch of the AM8112 VCA & ADSR.

AM8010 and AM8007 Euro Rack Modules Launched
