•
Envelope/LFO Selector Dropdown Menu: Selects whether Envelope/LFO 1 or Envelope/LFO
2 controls the filter modulation.
•
Pitch Tracking Drop Down: Engaging the Pitch Tracking initiates a function where the Filter
modulation and Pitch Tracking work in tandem, meaning that the filter will move its starting
point in the frequency spectrum based on the note that is being played. There are three
different pitch to filter frequency ratios: 1/3 Octave, 2/3 Octave, and 1 Octave. So for
example, if you set your Pitch Tracking to 1/3 Octave and play a low E then an E up one
octave, the filter's frequency starting point will move up 1/3 of an octave with the higher E
from where it was for the lower E. If you set the your Pitch Tracking to 1 Octave, the
frequency starting point will move up a full octave when moving from a low E to E at the next
octave.
Mix 1 & 2
•
Mix 1 and Mix 2 Blocks: The four meters labeled Voice 1 through 4 monitor the signal ratio
routed through Processors 1 & 2. Please note that setting the Destination of Mix 1 to Output
1 Only and Mix 2 to Output 2 Only is necessary in creating stereo effects. Each Voice's
position in the stereo spread is set with the Processor Pan control in each of the Voice blocks.
•
Destination Dropdown Menus: Choose the final Output Destination of Processors 1 and 2. It
is possible route the signal as follows
o Output 1 Only: Routes all of that Processor's signals to the C4's Output 1 jack.
