•
TRIANGLE STATUS
([WAVE SELECT] relating to the waveform concerned)
: activates (TRIANGLE
STATUS=ON) / deactivates (TRIANGLE STATUS=OFF) the triangular waveform.
•
TRIANGLE LEVEL
([WAVE MIX] relating to the triangular waveform)
: regulates the level of the signal
in a range from 0 (signal level zero) to 100 (maximum signal level).
•
TRIANGLE WRAP
([WAVE CTRL] assigned to this waveform)
: sets the degree of deformation of the
waveform in a range from 0 (waveform not modified) to 100 (maximum deformation). Using
this parameter will allow you to add a large number of overtones to the fundamental.
If you now select the PULSE folder, you will select the page for programming the square (pulse)
waveform generated by the first oscillator. The video page displayed is as follows:
comprising the following parameters:
•
PULSE STATUS
([WAVE SELECT] relating to the square waveform)
: activates (PULSE STATUS=ON)
/ deactivates (PULSE STATUS=OFF) the waveform concerned.
•
PULSE LEVEL
([WAVE MIX] associated to the square waveform)
: regulates the level of the square
waveform in a range between 0 (signal level zero) and 100 (maximum signal level).
•
PULSE WIDTH
([WAVE CTRL] assigned to the waveform concerned)
: regulates the pulse width in a
range between 0 (minimum pulse width) and 100 (maximum pulse width). Setting this parameter
with minimum or maximum values allows you to enrich the harmonic spectrum of the sound.
If you now select the MOD folder you will display the parameters relating to the signals which will
modulate Osc.1. The video page comprises:
containing the following options:
•
OSC 2 FREQUENCY MODULATION
([FM])
: sets the depth of modulation of the frequency of
the signal generated by Osc.1 by the signal originating from the second oscillator.
•
LFO1 MOD.DEPTH
(LFO1 Modulation Depth, [LFO1 DEPTH] of the OSCILLATOR 1 section)
: regulates
the depth of the frequency modulation of the signal originating from LFO1 on the signal
leaving the first oscillator. The range of values is –50 (maximum frequency modulation with
