was created by Paul
Schreiber in 1998. The system was created in part due to the renewed interest in large-format analog modular systems that occurred in the late 1990s. Between 1998 and 2021, over 8000 modules were sold. The company, Synthesis Technology, also offered a limited number of modules in

MOTM systems use a ±15 volt power supply for most modules, with an additional 5 volt power supply required for some digital modules. Audio signals are the standard 10 volts, peak to peak. The MOTM system modules are all "5U" high (1U being 1.75 inches), and multiples of 1U wide. All 5U MOTM modules

In Euro format, most of the currently available modules offer functionality that does not currently have an equivalent in MOTM 5U format. The E440 Discrete OTA VCF module is one exception, being very similar to the MOTM-440 (which is based on the SSM 2040 filter from the

Although full MOTM systems are only available in 5U format, the currently available Frac and Euro modules provide unique functionality that is somewhat different from the 5U MOTM modules. For example, in Frac format, the MOTM-1190 (Dual VCA) and MOTM-1800 (Looping

DIY synthesizer retailer synthCube took over distribution of MOTM modules in 2015, when synthCube acquired the assets of
Bridechamber. Synthesis Technology stopped manufacturing Eurorack modules in July, 2023, as a result of Paul Schreiber's planned retirement.

use 1/4-inch jacks for audio/CV signals. Euro and Frac modules use 3.5mm" (~1/8") jacks. MOTM modules can be mounted in a standard 19" rack using MOTM 19A rack rails, although many users have custom cabinets made of metal or wood.
