With UVX670 we're heading back in time to the '80s to deep-dive, layer and combine sounds from two unique, underrated analog gems from Japanese synthmaker Akai; the VX600 and the AX73. Both are six-voice analog polysynths, the VX600 being a pad monster with dual VCOs per-voice and the AX73 being remarkable for leads and basses with a 6 VCO architecture usable in either poly, stacked or unison modes through Curtis 4-pole 24/db resonant lowpass filters.

These two synths both employed versatile modulation systems capable of a wide range of sounds. The VX600 had a complex mod matrix, 2 LFOs per voice and allowed frequency modulation. The AX73, with 1 LFO per voice has variable pulse width with PWM usable on any of the waveforms. Individually, neither the VX600 or AX73 have a well-known vintage classic status, but it's not due to lack of capability or rich sound potential. Combined, these synths make an incredible complement, each lending strength to the other and creating some truly powerful sounds when employed together.
