"This unit produces VCO CV (control voltage) signals and trigger (gate) signals so that you can use an electric guitar, microphone, or other transducer output (from an acoustic instrument, for example) to "play" a synthesizer like a KORG MS-10 for example.... A variety of remote control input jacks let you use foot switches for more freedom and flexibility during live performance. With this amazing unit you can instantly put together your own guitar synthesizer, vocal synthesizer, etc., by simple connection with any synthesizer equipped with VCO CV IN and TRIGGER (Gate) IN input jacks."

KORG MS02

"The Korg Interface MS-02 is designed for the purpose of connecting Korg MS-Series synthesizers with other synthesizers available throughout the world. This sophisticated signal processor greatly enhances the performance possibilities of the MS-Series. Among presently available music synthesizers, there are two different types of control system used for the VCO (voltage controlled oscillator) and EG (envelope generator). One of these systems is used by Korg and Yamaha; the other is employed by every other synthesizer manufacturer. The Korg MS-02 provides you with a way to change the control signals of one system into the control signals used in the other system. In this way, it acts as an interface so that any two synthesizers can be used together, provided that the synthesizers are equipped with the conventional input and output jacks for control voltage and trigger or gate signals."

"it is a great instrument that can expand with many and many features the KORG MS series system. the Korg X-911 is as easy to use as any effects device, yet will produce extremely complex sonic variations. No special guitar pickup is required. Merely patch your guitar, microphone, or other instrument into the X-911 and play one note at a time. Simple pushbuttons on the front panel let you choose five different instrumental sounds including bass, trumpet, and flute, along with FIVE synthesizer waveforms which can be varied freely to get a wide variety of different effects. Any or all of these may be mixed together to produce 2047 different tone color combinations. Also, you can use a foot switch to instantly raise or lower the X-911's pitch an octave above or below the guitar pitch. Or you can play in unison with yourself with two lead lines a third or fifth apart. Footswitches can also be used for instant witching on or off of such effects as portamento and hold. There are even rear panel jacks for interfacing with other synthesizers such as the compact Korg MS-series to add even greater sound synthesis capability. Working voltage: 220 / 240 volts"
