FMinate (pronounced "effeminate") is a drum machine Audio Unit that uses a combination of FM and subtractive synthesis to generate a wide variety of percussive sounds. The tabbed interface provides controls to produce kick, snare, hi mid and lo tom, closed hihat and open hihat timbres; all sounds are triggered via MIDI. The interface was created in Cocoa, but a generic Carbon interface is also provided for hosts that do not support Cocoa interfaces in Audio Units. The Cocoa interface has been tested and works in Garageband, Logic and AULab.
