Multivox | MX-65


The Multivox MX-65 Polyphonic synthesizer manufactured from 1977-1978. It has six voices. Piano, strings, clavichord, honky-tonk, piano and organ. The voices themselves are different combinations of the filter and envelope positions that you can switch between. The filter is controlled with an envelope with 3 modes. A fast attack/fast decay mode, an ‘expand’ mode with resonance emphasis, and a fast attack/slow decay mode.

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. 

Connections include 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.

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.
