the drum controller, sample and hold, and ribbon controller. Early Micromoogs had slightly different panel labelling from serial number 1500 "Articulator" become "Loudness Contour". Later Micromoogs also gained an extra potentiometer on the back to adjust the keyboard output tracking. There were also internal changes to the keyboard. The Micromoog has an audio input allowing external audio to be run through the filter and VCA. The connections on the rear connection panel are as follows: Outputs: LO Audio −10 dBm, HI Audio +12 dBm, S-trig, KBD, Access(ory) power ±15 VDC, 50 mA. Inputs: filter, oscillator (0.95 volts per octave), S-trig, Audio Modulation The Micromoog served as the basis for the Multimoog, a similarly styled, but more generously equipped synthesizer featuring two VCOs, a larger 44-note keyboard, greater modulation options and an early implementation of keyboard aftertouch functions. Filter modification The Micromoog has a "fault" that limits its bass timbre. The modification can be found here and has been said to make it able to compete with the Minimoog on a one oscillator level.
