Oscillator DCO 2 has the same functionality with the addition of a [PITCH OFFSET] control (2) that allows
the interval between the two oscillators to be adjusted. This could be any interval at all - a third, a fifth, a
seventh etc. Greater intervals can be obtained by changing the [TRANSPOSE] control (4).
ACTION:
Turn up the volume (37) for Oscillator DCO 2 and set up the oscillators as shown in Figure 1.
Adjust the [PITCH OFFSET] control (2) so that the two oscillators are in tune when a note is
played.
ACTION:
Turn down the volume (38) for DCO1. Rotate the [PITCH OFFSET] control (2) and note that
Oscillator DCO 2 can go up or down about 5 or 6 semitones. Therefore any required interval
between the oscillators can be obtained.
It is normally recommended to make Oscillator DCO 1 the fundamental pitch and to set
Oscillator DCO 22 to the required interval above the fundamental.
The [PITCH OFFSET] control (2) also enables the two oscillators to be very slightly detuned against one
another.
ACTION:
Set up the oscillators as in Figure 1 and fractionally increase the setting of the [PITCH
OFFSET] control (2). This gives a rich phasing affect very characteristic of the synthesiser.
There are also separate volume controls in MIXER 1 for each oscillator (37)(38).
