Frac Rack, FracRak or Frac is the modular synthesizer format designed by John Simonton of PAiA. It has a mainly USA following largely through the popularity of Blacet modules.[1][2][3]

Like the Eurorack format, Frac is considered a 3U format. The height of most modern modular synthesizer modules is measured by the number of vertical units it consumes in a standard 19" equipment rack. Modules conforming to the 3U format will take up three vertical units in a 19" equipment rack. Each vertical rack unit is 1¾", so a 3U module is 5¼" tall. The Frac format has a standard width unit of 1½". So 3" and 4½" wide modules are common in this format.[1]

Note that even though the height of both Frac and Euro modules are 3U, differences exist in the mounting system.[2][4][5]

Frac format modules typically use 3.5 mm connectors and plugs for patching, although there are companies that offer modules with banana jacks e.g. BugBrand, Metalbox.[6][7]

Power requirements for Frac modules are typically ±15VDC. Current draw depends on the module. The control voltage is 1V/octave.[1][2][4]
