The Algorithm (ALG) Page
Source 2 (Src2)
This one’s even more programmable. Like Src1, you choose a control source from the list. But
instead of setting a xed depth, you can set a minimum and maximum depth, then assign
another control source to determine how much depth you get. Try this example. (Make sure Src1
is set to OFF rst, so the two sources don’t interact.) Start with Program 199, and press Edit. Press
the PITCH soft button to select the PITCH page. Set the Src2 parameter to a value of LFO1, then
set the Minimum Depth parameter to 100 ct, and Maximum Depth to 1200 ct. Then set the Depth
Control parameter to MWheel. This lets you use the Mod Wheel to vary the depth of the
oscillation in pitch generated by the LFO.
Now, when the Mod Wheel is down, the pitch will oscillate between a semitone (100 ct) up and a
semitone down (the default waveform for LFO1 is a sine wave, which goes positive and
negative). With the Mod Wheel up, the pitch will oscillate between an octave up and an octave
down.
Since the Mod Wheel is a continuous control, you can achieve any amount of depth control
between the minimum and maximum. If you had set the Depth Control to Sustain, for example,
then you’d get only two levels of depth control: the maximum (1200 cents) with your MIDI
controller’s sustain pedal down, or the minimum (100 cents) with the sustain pedal up.
