AM8005 SH05 FiltersThis module is a unique and very powerful diode ladder VCF, which has three different modes selected by a front panel slide switch: Low Pass Band Pass High Pass All three modes have voltaged controlled frequency modulation. Frequency Cutoff and Resonance can be adjusted and there are 2x audio inputs and 2x CV inputs for frequency modulation. The module has a mixture of slide and rotary potentiometers. The AM8005 is a replica of the voltage controlled filter in the Roland SH-5 analog synthesizer. EuroRack Module: 16HP wide User Manual: Download PDF Detailed Description This 16 HP wide module has at its core a 4-pole low pass diode filter, along with a 1-pole High Pass Filter which can be used in conjunction with the diode LPF to create Band Pass and High Pass filter responses. In LP mode the signal is simply sent straight to the Low Pass VCF although the signal level is reduced down at higher Resonance levels, by use of a dual Resonance potentiometer. The filter will self oscillate a...
MODULAR 100M
AM8171 Sequential SwitchWhen Roland developed the System 100M they created a quad signal gate module, the 171, which also had a ton of multiples. The AM8173 module contains the same four signal gates built with modern components, and an onboard LFO clock, making it a very useful sequential switch, for both audio and CV signals.
MODULAR 2500
AM1005 Mod Amp (Special Edition)This 12HP module is a re-imaging of the four quadrant multiplier and VCA that ARP launched as the 1005 module in 1970, and which was included in the 2500 synthesizer. The AMSynths electronic design is close to the original, with CV inputs and level potentiometers for the VCA, and audio inputs going straight into the four quadrant multiplier without level controls. The aim is to make the design user friendly and easy to use.
LEGACY
AM8328 Mirage Filter (2025 Edition)Introducing the AM8328 Mirage Filter (2025 Edition) a limited re-release of the iconic 12HP module, now with a fresh twist! This exclusive edition features just 8 pieces, making it a must-have for any serious synth enthusiast. Built on the legendary CEM3328 chip, the AM8328 is designed to deliver exceptional sound quality with its unique inbuilt Q compensation and inverted phase input.
MODULAR III
AM1631 Dual Ring ModulatorThis module is a recreation of the Moog Dual Ring Modulator that Keith Emerson commissioned from Bob Moog in the 1970's. There are no original schematics so the circuit is an approximation using ideas from the Moog Bode Frequency Shifter and the Roland 700 Modular. The AM1631 uses a pair of LM1496 modulation IC's, and a 1458 Dual Op Amp. T
MODULAR 2500
AM1026 Preset VoltagesThis 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 and a source of preset voltages that can be manually selected.
MODULAR 2500
AM1013 Octave Fixed Filter BankThis 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 Synthesize 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.
MODULAR 2500
AM1031 Multi Purpose FilterThis 14HP module is a re-imagining of the ARP 1031 Dual Multi Purpose filter that was envisaged in 1970 as part of the 2500 analog modular synthesizer. The design never made it into production but it has now been recreated as the AM1031 module.

DIODE-01 Mono SynthThe DIODE-01 Mono Synth is a fantastic homage to the iconic Roland System 101, blending its classic charm with the added features of the 102. This single VCO synthesizer boasts a rich diode ladder filter, making it a must-have for any synth enthusiast. Built on two sturdy PCBs, the DIODE-01 fits perfectly into a 60HP Eurorack space or can be easily integrated into a Moog Mother 32 case.
