TRIMMER ADJUSTMENTS FOR CHANNELS A, B, C, & D
Tuning in your PRO-4 and your analogue synths.
INITIAL (range approx 2 octaves)
- tunes the PRO-4 to the synth.
SCALE (range approx 20%)
- adjusts the octave scaling of the PRO-4 to match the synth. When the PRO-4 leaves the factory, this is
set to the standard 1 volt per octave, but some synths may require some adjustment of this control if the
octaves are out of tune with each other.
It may be that your synth is slightly out of tune, so it will be necessary to tune the PRO-4 to your synth;
1, Tune your synth (when playing from its own keyboard) correctly with your digital synths first. Do this by
adjusting the tuning or pitch knob on your analogue synth whilst playing middle C on both synths. (To do
this, you may need to disconnect the analogue synth from the PRO-4).
2, Now, with the PRO-4 connected to the analogue synth, play middle C on your digital synth. Both synths
should sound. With a small flat blade screw driver, tune in the PRO-4 with your analogue synth by
adjusting the INIT trimmer on the front panel.
3, When your digital and analogue synths are once again in tune, play a key two octaves up on your
digital synth. Now adjust the SCALE trimmer till both synths are in tune. The analogue synth should now
play correctly across its range from your master keyboard.
Use a small, thin and narrow, flat blade screwdriver to do this.
