This is an emulation of a specific ARP 2500 'Wing Cabinet' assembled and recently sold by Larry the O (of 'Toys in the Attic', Vallejo, CA). The full story here:


Most of the functions have been pretty fully emulated; no claim is made the sound emulates any ARP instrument, only the controls and basic structure. Forty drop-downs stand in for the jack panels, providing two additional inputs to each patch row.

Approximations of the following modules:

- 1004 Oscillator.

- 1023 Dual Oscillator.

- 1045 Voltage Controlled Voice.

- 1036 Dual Sample & Hold.

- 1003 Dual EG.

- 1006 Filtamp.

- Dual Noise/Random Voltage.

Thanks to Larry the O for lending his moniker to this unique plugin.


32-bit, so will require jBridge, etc., (or a DAW that will bridge) for use on 64-bit systems.

The link on the website is to a Sync.com folder that also contains the .osm Synthmaker source 'schematics', so anyone with SM, or it's successor Flowstone, can alter it to suit. It's hoped that anyone who makes significant improvements will share the result with everyone.

As this was originally built for my own use only, there are no presets included; I wanted to come at the instrument anew each time, as one did with vintage analog hardware.

Made with SynthMaker
