Possible applications include: LFO modulated vibrato, pitch-bend "choke" effects, and sample-and-hold controlled glissando and random note effects. With the MS-04 you have foot control over these and other effects so your hands are free to play the keyboard. The MS-04 can be used with Korg and other synthesizers equipped with external control jacks.
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.
