Of course, any “best of” list is subjective by nature. I’ve done my best to make this as objective as possible. I’ve included not only my own bias but also the opinions of others (in real life; in online forums, and by which brands professionals use). I’ve also taken into account the number of models and the objective nature of the models in each brand.
We’ll get into each of these brands in greater detail to explain why they made this list. I’ll also include several module examples for each brand along with a link to their official website and a bit of the company history.

Moog Unit – also called MU or 5U, is a large, full-figured module format. This is the format built by Synthesizers.com. MU is 8.75″ tall (5U) and comes in widths of 2.125″ which is 8 spaces in a 19″ rack. Modern MU uses the same panel size as Moog modulars but uses the Synthesizers.com power connector which has become a standard. Power is +/-15v and +5v. MU uses large knobs and 1/4″ jacks. Panels are typically black with exposed metal flanges on each side. Enclosures can be hardwood, portable or 19″ rack.
EuroRack – is the popular small format at 128.5mm tall which is about 5″ and close to 3U. Eurorack uses the smaller 3.5mm jacks and usually smaller knobs. Power systems for Eurorack use a flat cable to provide +/-12v,5V. Panels are a variety of colors, often silver. Typical enclosures are boxes, foldable or 19″ rack.
Other form factors are less common but still available:
FrackRack – is 3U tall (5.25″), uses a power connector like MOTM with +/-15v and 3.5mm jacks. Frackracks are close to Eurorack and they can be used together with certain considerations. Panels are a variety of colors, often black. Enclosures are typically 19″ rack.
MOTM – 5U = 5×1.75″=8.75 tall like MU, but comes in different width increments and has a thick flat panel. MOTM uses a 4-pin power connector to provide +/-15v, later offering 5v. MOTM modules use 1/4″ jacks. Enclosures are typically 19″ rack.
4U – 4×1.75″= 7″ tall panels, typically flat and silver. These include Buchla, Serge and others. Connectors are often a combination of banana jacks for control signals and 3.5mm for audio. Power is typically +/-15v but vary in connector style. Enclosures are typically 19″ rack but sometimes foldable boats. 4U systems often are used without a traditional keyboard controller.
