As can be seen, the SAW and TRIANGLE video pages differ from those displayed for Osc.1 in
that the SAW SPREAD and TRIANGLE WRAP parameters are not present, while the PULSE is
identical. Refer to the descriptions of the pages relating to the first oscillator for the information
you require.
By selecting the MOD folder, you can how display the video page relating to the oscillator
modulations and pitch.
containing the following settings:
•
LFO1 MOD.DEPTH
(LFO1 Modulation Depth, [LFO1 DEPTH] of the OSCILLATOR 2 section)
: regulates
the depth of the frequency modulation of the signal originating from LFO1 on the signal
leaving the second oscillator.
The range of values is –50 (maximum frequency modulation with opposite signal phase
originating from LFO1), 0 (no modulation), +50 (maximum modulation).
•
PWM DEPTH FROM LFO1
(Pulse Width Modulation Depth From LFO1, [PWM DEPTH] of OSCILLATOR 2
section assigned to LFO1)
: regulates the depth of modulation of the pulse width (PWM=Pulse With
Modulation) generated by Osc.2 by LFO1.
The range of values is –50 (maximum modulation with opposite phase), 0 (no modulation),
+50 (maximum modulation).
•
PWM DEPTH FROM LFO2
(Pulse Width Modulation Depth From LFO2, [PWM DEPTH] of the OSC.2
section assigned to LFO2)
: regulates the depth of modulation of the pulse width generated by
Osc.2 by LFO2.
The range of values is –50 (maximum modulation with opposite phase), 0 (no modulation),
+50 (maximum modulation).
•
PWM DEPTH FROM EG
(Pulse Width Modulation Depth From EG, [PWM DEPTH] of the OSC.2 section
assigned to EG)
: regulates the depth of modulation of the pulse width generated by Osc.2 by the
envelope generator (EG).
The range of values is –50 (maximum modulation with envelope reversed), 0 (no modulation),
+50 (maximum modulation).
