Akai AX-73

Released in 1986

The AX-73 is a 6-voice analog synthesizer with one oscillator per voice, in a very similar voice architecture to Akai's AX-60. The AX-73 has a 73-note velocity-sensitive keyboard, and has a unique feature of having inputs for use with Akai samplers (S612, S900, S950), allowing those samplers to use the filter and envelopes of the AX-73.
