Korg X-911

Korg X-911 Image

The Korg X-911 is a very underestimated synth. What it was intended to be, was a stand alone guitar synthesizer. What it now represents, in these enlightened times, is an all analog, quite unique, signal processor/effects unit. Whereas a true guitar synth really requires its own dedicated pickup arrangement, this unit simply accepts a standard 1/4" jack input. Just patch your guitar, microphone, or other instrument into the X-911 and play one note at a time. Sporting both CV/Trigger inputs AND outputs, these features alone, make it quite a useful little toy.

The front panel is divided conveniently into semi-preset traditional sounds, called "Instrument", and more adventurous sounds with the nomenclature "Synthe". The Instrument sounds are named Electric Bass, Tuba, Trumpet, Dist. Guitar, Violin and Flute. The Synthe sounds are designated as graphical waveform icons (Pulse, Ramp, Square). Every voicing has adjustable parameters, with most of the Instrument sounds having a filter control, bar the Violin, which has an envelope control. The Synthe sounds all have envelope controls, namely Attack and Decay.

The two sections may be overlaid or used separately, with control via the central balance slider. Many features such as Portamento, Interval, Hold etc. are foot switchable via inputs on the front panel. Naturally, the all important Voltage Controlled Filter is in residence, as is a Portamento control. Velocity Response/Touch Sensitivity is controlled by a 3 way switch. All in all, this unit is ideal for those Soundmeisters seeking to distance themselves from the all too common sameness of the modern digital era.

@ben : can you do a test with the CV/TRIG IN connectors? This way you will know that the portemento works ot not.

Just got one. Sounds great but when tracking an external signal there is always a fair bit of portamento (even with the portamento pot at 0). Anyone know if this is a fault and if so, how it can be fixed?

Impressive demo - certainly seems to have better tracking and less glitching than any other PtoV guitar synth I've seen, or tried myself.
Also must help that you know how to play it for glitch free results.
The bass guit sound is especially good, but the leads as well.

Wow i can't believe this guy made this incredible piece of gear sound sooo horrible with the same stupid twangy riff! I'm a bit confused why this is allowed to be a representation of this equipment that people put a lot of time, energy, and creativity towards. But, It's not the first time I've heard a horrible demo. I can see the potential and i would love one of these!

I got my X-911 with a few small Roland foot switches, and they work fine. They're probably older versions of the current DP-2 - cheap unlatched sustain pedals.
