Global Detune

Rotate the trim pot to detune all voices uniformly, for example to play alongside instruments tuned to 432 Hz. Turn it to the right to raise the pitch and to the left to lower it. The detune range is up to a half step in either direction.

By switching DIP Switch 7 to on, you turn this knob into a Pitch Drift pot instead. When enabled, turning the trim pot leftwards affects Katla’s tracking accuracy. Each voice is assigned a center note, and the further a played note is from that center, the more it will drift in pitch. Because the center notes differ between voices, the amount of detune varies from voice to voice.

Turning the trim pot rightwards detunes all voices globally. Using this feature, each voice is shifted by the same amount every time you play a note, uniformly across the entire keyboard.
