"Moog Liberation – vintage analog synthesizer, complete, functionally "great to excellent"
The Liberation is virtually identical to the Moog Prodigy, and includes all the same waveforms and functions PLUS a 44 note keyboard, ring mod, polyphonic mode, noise, and auto-triggering S&H. The oscillator synch works fine and the Moog filter sounds great. The modulation switches and wheels on the neck work for volume, filter, glide, etc. The pressure sensor does not work, therefore the wheel for pressure sensitivity doesn’t do anything; turning on the pressure sensor simply turns on the selected function 100%, which is musically useful so not a problem. This is still completely usable, you just can’t get the “expressiveness”, and I think it’s an easy fix. Other than this I would describe it as functionally excellent with all keys playing in tune and triggering as they should.This is a complete setup, including the power supply interface module and the extra-long cable. Ready to play and needs nothing.
The neck was purposely designed with the correct offset for it to fit in almost any keyboard stand, so aside from playing it as a keytar it’s also an easy way to add a 44 note CV/trigger keyboard to your rig!
Cosmetically it’s very nice but vintage; the white finish has crazing, small chips, and imperfections as shown in the photos, but overall this Liberation shows very nice for a vintage keytar. No cracks, no damage, the keys are all perfectly straight, smooth and perfectly functioning. No signs of it ever being dropped, abused, no key misalignment, etc. The sliders and knobs all move smoothly and work fine, but they could use a cleaning because when you look inside each slider you can see some some dirt and debris. This doesn’t affect the function at all, but it’s something I would do if I were keeping it.
This one is interesting and different from most other Liberations that I’ve seen because it has the following FACTORY installed differences: a pitch bend wheel instead of a ribbon controller (I prefer the wheel over a ribbon); an extra ON/OFF switch on the neck to for sending CV/trigger to an external synthesizer (this is slick if you’re using this to control other gear on stage); there are two 1/4'’ inputs on side of the synth. These outputs are not standard and I don’t see them on most Liberations on the internet, but I believe they are a factory mod. I believe they’re inputs to modulate volume and filter using a foot pedal controller. I wasn’t able to fully test them because I don’t have the correct pedals – probably needs either a variable resistance pedal, or possibly a variable voltage pedal (like a Moog 1120 pedal). An ordinary on/off pedal does cause changes – it worked to switch the volume on/off from one of the ports, so I believe that input controls the volume and the other one controls the filter."
