MOTM is the name of the modular synthesizer

Modular synthesizer

The modular synthesizer is a type of synthesizer consisting of separate specialized modules connected by wires to create a so-called patch. Every output generates a signal – an electric voltage of variable strength...

 system manufactured by Synthesis Technologies.

History

The MOTM system was created in 1998, and production continues, with over 8000 modules sold.

Specifications

It uses a +-15 volt power supply for most modules, with a +5 volt power supply also required for some digital modules. The audio signals are the standard +-10 volts, peak to peak. All of the modules use 1/4" jacks for audio/CV signals. The modules are all "5U" (1U being 1.75") high, and multiples of 1U wide. MOTM modules can be mounted in a standard 19" rack with MOTM rails, or can be mounted in custom cabinets, etc.

Frac Rack

In early 2006, The "Frac Rack" series of modules were released, using 3.5mm jacks and a smaller overall form factor to fit in with PAiA Electronics

PAiA Electronics

PAiA Electronics, Inc. is an American synthesizer kit company that was started by John Simonton in 1967. It sells various musical electronics kits including analog synthesizers, theremins, mixers and various music production units designed by founder John Simonton, Craig Anderton, Marvin Jones,...

 and Blacet modular systems.
