Akai | VX90

Description

With an identical voice structure to the AX73, the VX90 is little more than a rack-mount version. It is a MIDI equipped six-voice analog synthesizer with advanced digital controls and functions. Like the AX73 it has an auto-tune function and a nice VCF lowpass/hipass filter and envelope section. The VX90's memory capacity holds up to 100 patches. It can be played polyphonically or in a stacked unison mode for that thick lead sound for your rave and techno anthems. A really cool feature of the VX90 is that you can plug the Akai samplers in to it and run their samples through the VX90's analog filter and envelope sections.

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.
