Entry for owner-sampler Akai

This is an analog synthesizer with VCO (one), monotimbral, polyphonic voice 6
-VCO: saw, pulse, triangle, triangle, saw +, presence of PWM for all waveforms
-Noise
-Low-pass filter with HPF
-LFO: saw 1 and 2, pulse, triangle, random destination: VCO, VCA, VCF
-2 Envelopes for the VCA and VCF. The same envelope can be used for 2. The envelope 2 can be used to control the height of the VCO
Chorus 2-modes
-3 Modes: poly (polyphony max), dual (two voices per note) and Unison (6 voices per note) with detune
Portamento-
-100 Presets

UTILIZATION

The control panel is simple and is limited to buttons of type "numeric" with two faders, one for volume control and the other for editing.
Editing is done by sub-menus, it has unfortunately not blessed with lots of knobs which is obviously bad, but the edition has the advantage of being fast on both the relative simplicity of synthesis scheme (a VCO), the ability to access by shortcut to each of the parameters and especially the fader editing, which allows you to scroll the values ​​at breakneck speed.
The pitch wheel is used to control the pitch and / or filter cut-off (with a dimmable) which is particularly interesting in light of the absence of knobs. The mod wheel controls the depth of the modulation by the LFO.
The AX73 is taken in hand very quickly.

SOUNDS

This is my only analog VCO, my point of comparison is the Roland JX-10 to COD. The AX73 was surprised by the strength of its low, especially in unison mode without even touching the detune. The imprecision in the patch and the height afforded by the VCO is tasty though to agree with other synthesizers must be used autotune and the small knob to Fine Tune on the back of the instrument.
The chorus is warm, and fortunately not necessary for the instrument "sounds".
Can be drawn from groundwater is not suitable but the main use we can make. The leads are not as powerful an attack on the digital unfortunately.
White noise can draw some nice effects. It is separated from the VCO so that it is possible to play on scale VCO / Noise + Sampler.
I like the presence of PWM, when the speed is set to 0 it can "distort" the waveform of the VCO so highly appreciated.
Finally the velocity of the keyboard is assigned to the volume control but it is also possible to set the cutoff frequency of the filter.

OVERALL OPINION

I use this instrument for 2 months. In fact, I bought it down on e-bay for 60 €, was described by the salesman reminded me a problem with internal battery, which proved to be accurate at the reception.
The AX73 is in addition to my set for bass and sound effects, including controlled via a foot pedal south.
The synthetic scheme is simple with a single VCO, but the dual mode and harmony overcomes this simplicity and richness, the thickness of a single VCO is far more COD!
A wide backup space (100 presets) is offered with the ability to export audio files for storage.
This is a synthesizer uncommon, interesting for its sound quality especially for low and by the presence of VCO, whose value is very affordable. Given the price I bought it after some minor repairs (batteries, battery holder, push-button autotune to replace a broken key keyboard and touch to change) I did a very good deal that I regret obviously not.
