Akai AX73

Akai AX73 Image

The AX73 is a surprisingly 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 keyboard. 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 standard ADSR VCA envelope generator. But unlike many other analog synths, this machine is MIDI equipped for easy integration and use in today's modern studios. The sounds are quite nice and are adequate for use in any style of music production. It also had special inputs for use with Akai's S-612, S-900 and S-950 samplers, allowing you to run those samples through the AX73's analog filters and envelopes.

I've had mine for a little over a year now, and I really like it. All adjustable parameters are accessible by the control panel, and not at all hard to navigate. There is a bass patch that is well known (actually from the AX60) and used on Bjork's first two albums. It's sort of a hollow, tube bass sound. The synth can produce pads very similar to the Sequential Prophet 5, which is surprising as it only has one oscillator per voice. The AX73 also produces some very cool sound effects - very sci-fi sounding, yet quite musical. It also makes a great keyboard controller as its solid (a bit heavy too) and has nice key action with velocity (although no after touch.)

My first proper synth, and still my only one. I've only just started playing around with the patches recently, but it's really surprised me as to what it can do. It's more suited to pad sounds IMO but can still make a fairly decent lead.

It was my first synth, and how glad I am it was! great sounds, made even better with dual or uni mode, and great programmability, and that "extra octave" sturdy keyboard. Great value for money.

I have an AX73 in my set-up and I love it. The patch editing looks complex but it's surprisingly easy and some of the sounds I've acheived are amazing. The keyboard action is also very nice. I have been lucky with it as it's previous has taken very good care of it. When ever I go up to the chambre des musique the big white akai is the one that gets turned on first.
