Algorithm Basics
Velocity Tracking
A positive value for velocity tracking will raise the pitch as you trigger notes with higher attack
velocities. This is great for getting a trace of detuning based on your attack velocity, especially in
drum programs, where you can make the pitch of the drum samples rise slightly with higher ‐
velocity Note Ons, just as drums do when you strike them harder. Negative values will lower
the pitch as you increase the attack velocity.
Programmable Parameters
Source 1 (Src1)
This parameter takes its value from a long list of control sources including every MIDI control
number, a host of LFOs, ASRs, envelopes and other programmable sources.
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
PC3K 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.
