"Up for auction is a Multivox MX-65 Polyphonic Synthesizer. It is an analog poly keyboard that was made in Japan from 1977 to 1980. Very very rare.

It has six voices. Piano, strings, clavichord, honky-tonk, piano and organ. The voices them selves are just different combinations of the filter and envelope positions that you can switch between. The filter is interfaced with the envelope with 3 modes. A fast attack/fast decay mode, an ‘expand’ mode with resonance emphasis, and a fast attack/slow decay mode.

The MX powers on and off from the volume knob. A red LED indicates its status. It powers up and tunes perfectly from start up. There is a tuning pot on the left hand side to control the master tuning.

The front panel is not deep, but it definitely gives you some control over the MX-65's presets.
There are envelope shape controls, an LFO (delay, depth, speed), and 3 Ensemble/Chorus modes.

On the rear panel there is has Gate Out and VCF control in. The Gate Out has positive and negative polarity outputs. The VCF control in is a control voltage input or pedal control. As a cv input it is 1.3 v/octave. Very unique feature set.

This synth can be very lush, especially with a touch of fx. I have made a quick demo, with some of reverb and delay from Ableton. The string and piano sections are my favorite. [posted here]
