External Inputs

Katla features five external inputs. To enable them, press the EXT button in the Master section. Control their level with the Noise/EXT level slider and shape the tone using the tilt EQ via the Color slider. After this stage, the external signal is routed through the rest of Katla. Use the filter, distortions, envelopes, and LFOs to process the external audio, blending it with Katla’s internal voices.

Tip

Need even more distortion? Try routing the headphone output to External Input 1. This feeds Katla back into itself.

Input Distribution

Katla shares external signals across the inputs in different ways depending on connected inputs:

• Only Input 1 connected: Katla routes that signal to all voices, allowing you to hear the input on every played note.
• Inputs 1 and 2 connected: Katla treats them as a stereo pair and hard-pans the signals, while also distributing them to voices 3, 4, and 5.
• Empty inputs receive their signal from the source indicated by the arrow on the back panel.
