The Algorithm (ALG) Page
Src1 works in tandem with the parameter beneath it on the page: Depth. Choose a control
source from the list for Src1, then set a value for Depth. When the control source assigned
to Src1 is at its maximum, the pitch will be altered to the full depth you set. For example,
if you set Src1 to MWheel, and set Depth to 1200 ct, the pitch will rise as you push the
Mod Wheel up on your Forte SE or MIDI controller, reaching a maximum of 1200 ct (12
semitones, or one octave).
Source 2 (Src2)
This one's even more programmable. Like Src1, you choose a control source from the list.
But instead of setting a fixed 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 first, 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.
Alt Input for Algorithms (Cascade Mode)
Cascade mode is a particularly powerful feature of the Forte SE that allows you to create
unique algorithms of previously unattainable levels of complexity. The following three figures
show the signal path of a program configured using the Forte SE's Cascade mode:
