MODULAR 2500
Overview AMSynths have developed a range of ARP 2500 modules that augment the Behringer 2500 range, or the modules can be used in any Eurorack system.
The Lost ARP Modules have been recreated in Eurorack. Ten modules were planned by ARP in 1970 but they never made it into production, until now.
Accurate replicas of the originals have been created with the AM1005, AM1019 and AM1006 modules. Fully featured they deliver more of the 2500 experience.
Sequencer Expansion The AM1021, AM1026 and AM1028 enable the original ARP vision of a complete sequencer subsystem to be realised.
All modules are in production.
MODULAR 2500
AM1028 Sequential Volts (Slave Module)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.

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.
MODULAR 2500
AM1004P Oscillator MixerThis AM1004P module expands the capability of the Behringer 1004 VCO by adding the waveform mixer from the original ARP 1004P. The original circuit has been carefully replicated. The module delivers all five waveforms indepedently as well as mixing them into a single output.
MODULAR 2500
AM1006 24dB Low Pass FilterThis 12HP module is a re-imagining of the ARP 1006 low-pass filter which was built around a traditional Moog transistor ladder. It has a cutoff range between 16Hz - 16kHz and goes into self oscillation from 200Hz upwards. The 1006 first appeared in the ARP 2500 synthesizer in 1970, as part of a combined filter and VCA module.
MODULAR 2500
AM1042 Triple VCAThe AM1042 is a 14HP module that re-imagines the "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.
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
AM1037 Dual VC Envelope GeneratorThis 14 HP wide module contains two identical voltage controlled ADSR envelope generators. The slope of the stages can be continuously varied from linear to exponential using a front panel control knob.
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.
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.
