Using the keyboard of a Hz/V type synthesizer to simultaneously play (control) an OCT/V type synthesizer ^

- Hz/V to OCT/V conversion

(1) Connect synthesizer A (Hz/V) and synthesizer B (OCT/V) as shown by the solid lines.

(2) Set the octave (scale) selectors on both synthesizers to 8' and set the tuning knobs to the center position.

(3) While playing the lowest note on the A keyboard, use the MS-02 Log Amp Frequency knob and the synthesizer B tuning knobs to match the pitch of B with that of A.
If you cannot get the same pitch by this method, change the connections to those shown by the dotted lines. Turn the Adding Amp Ch-2 level knob to the central x1 position and then slowly raise the Ch-1 knob. This will greatly increase the pitch of synthesizer B. If you need to lower the pitch of B, change the Adding Amp connection from the Ch-2 input jack to the Ch-1 input jack. Then set the Ch-1 level to x1 and adjust the pitch with the Ch-2 level knob.

(4) While playing the highest note on the A keyboard, adjust the Log Amp Width knob so that the pitch of B matches the pitch of A.
If you are using the Adding Amp and you can't get the pitch of B to match that of A, use the knob you set to x1 to roughly readjust the pitch.

(5) Repeat steps (3) and (4) as necessary until the scales of synthesizers A and B are perfectly matched.

Using the keyboard of a OCT/V type synthesizer to simultaneously play (control) an Hz/V type synthesizer ^

- OCT/V to Hz/V conversion

(1) Connect synthesizer A (OCT/V) and synthesizer B (Hz/V) as shown by the solid lines.

(2) Set the octave (scale) selectors on both synthesizers to 8' and set the tuning knobs to the center position.

(3) While playing the lowest note on the keyboard of synthesizer A, (the note that produces a CV OUT voltage of 0V) adjust the MS-02 Anti Log Amp Frequency knob and set the synthesizer B tuning knobs so that the pitch of B matches that of A.
If you cannot get the same pitch by this method, change the connections to those shown by the dotted lines. Make sure that the Adding Amp Ch-2 level knob is set to "0". Then perform rough pitch adjustment using the Ch-1 level knob.

(4) While playing the highest note on the keyboard of synthesizer A, (the note that produces the highest absolute value of the CV OUT voltage) use the Anti Log Amp Width knob to adjust the pitch of B so that it matches the pitch of A.

(5) Repeat steps (3) and (4) as necessary until the scales of A and B are perfectly matched.

Using the SQ-10 to control a synthesizer having

type trigger (gate) signals ^

- using the SQ-10 to control a synthesizer having positive trigger signals

If you employ the trigger processor on the MS-02, you can use the Korg SQ-10 Analog Sequencer for automatic control of any brand of synthesizer equipped with VCO CV IN and EG TRIGGER IN input jacks.
The figure above shows one example of how to connect the three units.

Using the MS-02 for rough pitch adjustment between two Hz/V type synthesizers ^

- using the MS-02 for rough pitch adjustment between two Hz/V type synthesizers

(1) Connect synthesizers A and B as shown in the figure above.

(2) Set the controls on both synthesizers so that the octave (scale) selectors are at 8' and the tuning knobs are set at the center position.

(3) While playing a note in the middle of the keyboard of synthesizer A, adjust the MS-02 Adding Amp Ch-1 level knob so that the pitch of B is the same as the pitch of A. For fine adjustment, use the tuning knobs on synthesizer B.
Note: Be sure that the Adding Amp's Ch-2 level knob is set at the "0" position.

Using the MS-02 for rough pitch adjustment when playing two Hz/V type synthesizers from one keyboard ^

Use the setting in figure a to lower the pitch of synthesizer B; to raise the pitch of synthesizer B, follow figure b when making connections.

- a] rough pitch adjustment between two Hz/V type synthesizers from one keyboard (lowering pitch)

Lowering pitch: [figure a]

(1) While playing the lowest note on the keyboard (the note that produces 0V CV OUT voltage) of synthesizer A, adjust the Adding Amp Ch-2 level knob so that the pitch of synthesizer B matches that of A.

(2) While playing the highest note on the keyboard of A (the note that produces the highest CV OUT voltage), use the Adding Amp Ch-1 level knob to fine tune the pitch of synthesizer B so that it matches A.

(3) Repeat steps (1) and (2) as necessary until the scales are matched.

- b] rough pitch adjustment between two Hz/V type synthesizers from one keyboard (raising pitch)

Raising pitch: [figure b]

(1) While playing the lowest note on the keyboard of synthesizer A (the note that produces a CV OUT voltage of 0V), use the Adding Amp Ch-1 level knob to adjust the pitch of synthesizer B so that it matches A.

(2) While playing the highest note on the keyboard of A (the note that produces the highest CV OUT voltage), use the Adding Amp Ch-2 level knob to fine tune the pitch of synthesizer B so that it matches A.

(3) Repeat steps (1) and (2) as necessary.

- modulation inputs for pitch bend and vibrato effects

Hz/V system [left side of figure]

(1) Connect the Hz/V type synthesizer and MS-02 as shown in the diagram on the left of figure 6.

(2) Set the Log Amp controls as shown on the diagram. Set the Adding Amp Ch-2 level knob to "0".

(3) Play the lowest note on the synthesizer keyboard and use the Adding Amp Ch-1 level knob and the Anti Log Amp Frequency knob to adjust the pitch to match some accurate reference, such as the Korg Tuning Trainer WT-10A or an electric organ.

(4) Play the highest note on the keyboard and use the Anti Log Amp Width knob to adjust the pitch to match a reference tone, as in step (3).

(5) Repeat steps (3) and (4) as necessary.

(6) Use the Adding Amp Ch-2 level knob to adjust the strength of the effect you get when you operate the external control unit.

OCT/V system [right side of figure]

(1) Connect the OCT/V type synthesizer and MS-02 as shown in the diagram.

(2) Play the lowest note on the keyboard (the note that produces a CV OUT voltage of 0V) and use the tuning knobs on the synthesizer to adjust the pitch to match an accurate reference, such as the Korg Tuning Trainer WT-10A or an electric organ.

(3) Play the highest note on the synthesizer keyboard (the note that produces the highest CV OUT voltage) and use the Adding Amp Ch-1 level knob and the Anti Log Amp Frequency knob to adjust the pitch to match your reference tone.

(4) Use the Adding Amp Ch-2 level knob to adjust the effect you get when you operate the external control unit.
