you can also annul one waveform (the triangular one, for example) to produce a waveform which
is different again:
When the OSCILLATOR1 option is selected in the SCOPE video page from PLAY PROGRAM or
PLAY TIMBRE, the display will show the sum of the three main waveforms in real time (see point
6.1).
We will now look at how to regulate the first oscillator.
In the EDIT TIMBRE MENU video page, select field 3-OSCILLATOR 1; the display will change to:
This video page contains the settings of the sawtooth waveform generated by the first oscillator.
The video page consists of the following parameters:
SAW STATUS
([WAVE SELECT] relating to the waveform concerned)
disables (SAW STATUS=OFF) generation of the waveform concerned.
SAW LEVEL
([WAVE MIX] relating to the waveform concerned)
range from 0 (signal level zero) to 100 (maximum signal level).
SAW SPREAD
([WAVE CTRL] assigned to the waveform concerned)
of the waveform, in a range from 0 (waveform not modified) to 100 (maximum modification).
Values of this parameter higher than 0 will give make the sound seem out of tune and give it
a feeling of space.
Now select the TRIANGLE folder and the display will show the video page relating to the settings
of the triangular waveform generated by the first oscillator. The video page comprises:
: enables (SAW STATUS=ON) /
: regulates the level of the signal in a
: sets the degree of modification
