Default Input: Selects the default configuration of the Input jacks. There are four different
options: Auto Detect (Default), Single Input 1, Dual Input 1 & 2, External Loop (Pre-
Processing). Go to the
•
Quick Bank Switch Using Footswitch (2 Seconds): By default you can only use the footswitch
to alternate between Preset Bank 1 (Green LED) and Preset Bank 2 (Red LED) from the
disengaged state. Checking this box allows you to alternate Preset Banks quicker AND from
the engaged state.
•
USB MIDI Skip Power Check: The C4 can receive MIDI PC messages via the pedal's USB port.
It requires MIDI DAW software or a MIDI host device with USB. The C4 should respond to
most devices, but some don't generate enough power for the C4 to recognize them as a MIDI
host (the MIDI Baby and qCONNECT from Disaster Area Designs are two examples). If your C4
is not responding to your MIDI host device, try checking this box.
•
Show Expression Pedal Calibration: If necessary, open this control set to calibrate external
expression pedals.
Preset Editor
Click the Sound Editor (wrench) icon in the Connections section to open the C4 Synth's Sound Editor
in the center tab. This is where all of the sound editing work takes place. The Sound Editor is broken
into several sub-sections, each containing a unique variety of virtual knobs and dropdown menus.
The following is a brief explanation of each Sound Editor sub-section.
Master Controls
The controls that populate the Master Controls section apply to all four Voices in the C4 Editor.
•
Input 1 Gain 1 & Input 2 Gain: Because the C4's pitch detector and envelope followers
respond differently depending on the level of signal going into the pedal and because the
output levels of different instruments vary so greatly, it can be helpful to adjust the level of
signal going into the effects processor. The two Input Gain controls make it possible to adjust
the level from Inputs 1 & 2 independently.
•
Master Depth: A master control for the modulation depth of Filter 1 and Filter 2. When
running both filters simultaneously the Master Depth control adjust the depth of both filter
to scale with their individual settings.
•
Mod Source (ENV / LFO): Adjusts the mixture of the modulation source. The modulation
source refers to the mechanism that moves (a.k.a. "modulates") the filters. The C4 has two
types of filter modulation: the envelope follower (ENV) moves the filter based on the players
pick attack, and the low frequency oscillator (LFO) modulates the filter back and forth at a
