Korg X-911

“It is a so-called guitar synthesizer. Roland is generally famous for guitar and synthesizer, but KORG also announced a compact model with less malfunction. Not limited to guitar, any instrument can be used as a source as long as it is a musical instrument that produces sound with a single note. You can mix several kinds of presets, or you can control the harmonic overtones like an organ’s drawbar to obtain a sound that can not be obtained with an effector.
Hold and portamento are also possible, envelope is also attached properly It can be said that it is a real synthesizer.
Operation confirmed.” Click here to search for synths on eBay

Korg X-911

“Up for sale is rare Korg X-911 vintage analog guitar synthesizer.

The unit appears to be working reasonably well, I noticed the TUBA sound seems to be only producing small noise somehow, but otherwise all other sounds working and sounding fine as well as all the knobs and switches working as they should. There may be a slight bad contacts on the BALANCE slider, which could probably also do with some servicing/adjustment. All the LED lights above each buttons lighting up correctly when pressed.

Cosmetically the unit is in very nice condition as you can see. There are some signs of wear and minor marks here and there, but nothing major. I’m including plenty of photos so you can see exactly how it looks.

Comes with the Original Plastic Overlay as shown.
Power cable included.”

Korg X-911 Project Machine

“Partially working with faults!

Instrument side:
Elec Bass LED always on (doesn’t Cancel) No sound either from this preset.
Tuba never switches on, so no response from this one either.
the other 4 work as intended, including trim pots.

Synthe side:
LEDs will light & cancel, but none are sounding.

I have a feeling this will centre around the filter chip rather than the buttons. Similar to the common fault in the Korg Delta. The parts are still available.

The left hand side of the panel is fully working, input, portamento/ interval/ tune/ octave all 100% on the 4 working voices. Still great fun to be had with this alone! Glitchy, Prog-type fun & Octave effects a-plenty!

Synthe filter knob not working, again pretty sure this is related to the synthe side. Possibly these tones go through the filter chip & the instrument side is filtered by resistors etc, as you have no control over those.”
