The upper half (at least) of OSC VOLUME also has another
important job. It controls the amount of filter saturation, men-
tioned a few pages earlier. The idea was to make OSC
VOLUME similar to the gain control on a guitar amplifier – the
signal starts distorting when you turn it up “too high”.
NOISE VOLUME
Simply the volume of the Noise generator.
PANORAMA
Via SHIFT + OSC BALANCE. Pans the entire program across
the stereo outputs.
OSC 3 VOLUME
Via SHIFT + SUB OSC VOLUME. The volume of oscillator 3
when it is switched on. If you would like all three main oscilla-
tors to have the same level, you should set OSC BALANCE to
the centre and OSC 3 VOLUME to 64.
SATURATION TYPE
Via SHIFT + OSC VOLUME. See above.
RING MODULATOR
Via SHIFT + NOISE VOLUME. Ring modulation means multi-
plying two signals together. Like FM, the result is highly
dependent upon the basic frequencies and complexity of the
two sources. For pure bell-like tones, use Sine waves only:
Restore ROM-A126, take SHAPE down to minimum. Select
oscillator 2 and do the same. Turn OSC VOLUME down to
minimum and RING MODULATOR (SHIFT + NOISE VOLUME)
up to maximum. Turn amplifier RELEASE up to around 90,
select oscillator 2 and experiment with the SEMITONE knob.
