The Akai AX-73 is a relatively underrated synth from the era of the Juno and Polysix. It has 6 voice polyphony and voltage controlled oscillators and filters, dual and unison mode, good PWM, FM and quite a lot of lfo waveforms compared to it's competitors. Although the higher pitched sounds of the AX-73 are quite thin and ugly it completely makes up for this with it's bass sounds. These are the fattest I've ever heard and sound smooth, deep, earthshaking and beautiful at the same time. Great DnB synth. This doesn't really come as a surprise as the filters come from the same chip as many of the Sequential Circuits synthesizers of that time. Reviewers on Harmony-Central gave this synth a 8.6 for its sound.
