Akai | AX73

Description

The AX73 is a good analog synthesizer that is still considered to be widely underrated and deserving of some recognition. It's a six voice analog synthesizer with an almost identical architecture to Akai's AX60. It also came in a rack-mount form as the VX90. It has one oscillator (VCO) per voice and allows for 3 playing modes: Poly mode uses one VCO per voice for six voice polyphonic pads, chords and strings. Dual-VCO mode stacks 2 VCOs per voice for a thicker three-voice sound. Unison mode stacks all six VCOs onto one monophonic voice for a screamin' lead!

The AX73 has a simple 24 dB/oct VCF (filter) and it has an interesting feature that allows the cutoff to be modulated by the VCO. It also has a flexible LFO with many variable waveforms, chorus, portamento, and a ADSR VCA envelope generator. This machine is MIDI equipped for easy integration and use in today's studios. It also had special inputs for use with Akai's samplers, allowing you to run those samples through the AX73's analog filters and envelopes.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
