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.

Love mine, it's seriously an awesome poly synth for the price range. I've recently moved to more of a digital setup so I'm going to sell mine! If anyone is interested - MelodicDreamerPDX@gmail.com

A sweet little VCO synth in a sturdy, confidence inspiring tank of a box with a nice keyboard. Programming isn't as much as a drag as you might think, and the VCO's have a sweetness to them that is underrated. It might not beat something like a Juno-6 or even Polysix, sonically, but for the low prices they go for it's something of a well kept secret. Solid basses, basic but sweet strings and filler pads, and dorky but fun EP's (due to the velocity sensitivity) roll out of this. You might move on from it, eventually, but it's a solid piece of gear for someone who want to actually play.

THis is a nice synth. I've recently picked up 13 pin din cabe to connect to an s950 sampler but I cannot seem to make the connection up to allow the samples to run through the synth. Has anyone successfully done this and have any tips? (mono mode?)

I love this synth,the pads [beep] but its great for blurpy, rubbery basses and funky leads. I've programmed a couple passable 303 patches and a bunch of big balsy bass patches on this machine. Its also great for those Curtis-driven Chroma-Polaris style electro noises and sci-fi sounds.

Looking at it you'd think it would sound thin and digital (and the old factory presets do) but with a bit of programming it's a rich sounding analogue monster.

I have an AX-73 for sale in BC that would be perfect for someone in the Pacific Northwest. Paul@PaulFitzZaland.com
