Pitch and Mod Controllers
Pitch Touchpad
The pitch touchpad is located on the left cheekblock. It works much like a traditional pitch
wheel or pitch bender lever but is more compact and less prone to wear out.
Like a bend lever or wheel, when not touched it is virtually centered and true pitch is heard.
Touching above the horizontal embossing will bend pitch upward, up to a whole tone sharp.
Touching below the embossing will bend pitch downward, up to a whole tone flat. Smooth
bends are achieved by placing your finger where the horizontal and vertical embossings
cross and then sliding your finger along the vertical embossing while maintaining contact. To
restore normal pitch smoothly, slide back toward center. Or, simply release and the bend will
spring back to center (none).
Mod Slider
The mod slider is the leftmost slider control on the front panel. The mod slider is not spring
loaded so its handle remains where last released. Typically, the mod slider is assigned to a
parameter that alters some aspect of the sound (e.g., vibrato, filter depth) when changed.
Function Buttons
The Function buttons are located beneath the "Function" label on the left side of the front
panel. In addition to changing operating Modes, these buttons serve Mode-specific
secondary functions.
