via the seller: "Aside from the normal Moog stuff, this thing has two KILLER features that set it apart from other synths. One is the aftertouch - if you press harder on a key after you play it, modulation sets in. On modern keyboards, aftertouch is a gimmick that I almost never use, but for some reason on this thing I use it a lot. I guess it's the lightness of the keys or something, but I find it super easy to pick out single notes from a chord and "express" them with aftertouch.
Even better is the polyphony feature. Playing an analog synth live means you always wish you had a second note (very few true vintage analog synths make more than one note at a time, including the Minimoog). But this thing has a polyphony feature. As I understand it, it's sort of like a built in organ type divide down system, and it's not true polyphony in that you don't get a second note that sounds the same as the primary note…but who cares! However it works, you can play fat sounding chords and grace notes unavailable to you on a minimoog.
On the extension on the left hand, you get some exceptionally useful controls, most notably the ribbon controller. As I say, I always play it tabletop like a regular keyboard, but I my left hand can still access all the controls on the extension just fine.
The body is made of wood, probably mahogany. It feels like a 70s Gibson…because it was made by the same people I assume. The Liberation is surprisingly light. Not at all a chore to strap on. It's 50lbs in the case with the supply, but by itself it's comfy.
As you can see, this one has been around the block a few times, but it's in perfect working condition. Power supply - fine, controls, fine, keyboard - fine. No noise or broken sliders. In the case, you'll find the power supply, and a ridiculously long cable that goes from the supply to the keyboard - the thing has got to be 50 feet long! There's a normal 1/4" output on the power supply to your amp."
via the listing: "This is a 120 volt US version Yamaha CS-15 which was dead when I bought it. The keyboard controller IC was shot, which is essentially the kiss of death for these CS models because that IC is no longer available anywhere. Five Star Engineering in Mesa was able to construct and install a component controller from scratch. One of the LEDs was busted and another didn't light so all the red LEDs were removed and replaced with BLUE ones. This is now a healthy and fully operational synth in need of a little cosmetic TLC."
