"Simultaneous VCO and VCF modulation. For full foot pedal control of such modulation effects as vibrato, random pitch, and glissando.

Ideal for Korg MS20 and other synths

Gives two separate output signals from simultaneous modulated VCO and VCF. Essential for the multi-keyboard performer

The Korg MS-04 is and expression pedal designed to be used with a synthesizer to control various modulation effects.

Applications include: LFO modulated vibrato, pitch-bend 'choke' effects, and sample-and-hold controlled glissando and random note effects. Foot control over these and other effects free your hands to play the keyboard! The MS-04 can be used with Korg and other synthesizers equipped with external control jacks.

This was designed to work with the Korg MS line of synths and it provides full control over the LFO or other functions.

LFO: WAVEFORM Use this to select one of four LFO output waveforms: Cyclic sawtooth and rectangle waves for vibrato, a random noise waveform for random pitch and tone color variations, and a 'glissando' waveform which is used with 'bend' for stepped variations.

LFO: SPEED This knob adjusts the LFO frequency or 'speed' of variation. Turn clockwise to increase speed.

LFO: LEVEL This adjusts the range of LFO variation. Press the pedal all the way down and set this knob to determine maximum variation.

BEND: WIDTH This adjusts the range of (pitch) bend variation. Turn clockwise (+) away from the center click-stop for an upwards bend- turn counter clockwise (-) for a downward bend. Press the pedal all the way down and set this knob to determine maximum variation. LED indicator This flashes on and off to indicate LFO speed when cords are plugged into output jacks. Useful for judging speed of vibrato, glissando and other effects. Pedal Controls depth of modulation. Press all the way down for maximum modulation effect.

OUTPUT-1 Mode Selector Use to select output mode for OUTPUT-1 jack. Can be set for LFO, BEND or a combination of the two.

OUTPUT-1 (x 1) jack This is usually connected to the synthesizer VCO (FM IN) to control pitch variation. A maximum 1-octave variation is possible (+-1V maximum variation.)

OUTPUT-2 Mode Selector Selects output mode for OUTPUT-2 jack. OUTPUT-2 (x 4) This is usually connected to the synthesizer VCF (fcM IN) to control tone color variation. Maximum variation is four times that of OUTPUT-1 (+-4V maximum variation.) Output Selector This determines which jacks will provide an output signal. It can be set for both outputs 1 and 2 together, or for just output 1 or just output 2 alone.
