Voices

Katla features five voices, each with individually adjustable parameters. For each voice, you can set its level, octave, and waveform, disable it by pressing the activation button. Available waveforms are square, sawtooth, shark-tooth, triangle, and sine. They are arranged from top to bottom in order of harmonic content.

Voice Modes

Choose between Round-Robin or Unison voice modes.

Round-Robin Modes

Choose Round-Robin mode by pressing its button, represented by a rotation symbol. In Round-Robin mode, each note is assigned to one of the five voices in sequence, creating a rotating pattern of sound. You can switch between three different Round-Robin modes by pressing the same button. The first mode cycles forward through the voices, the second cycles backward, and the third selects voices at random.

Unison Modes

In unison mode, all active voices are automatically assigned to the notes you play and dynamically adjusted based on how many keys are held. This means that at any moment, up to five voices are in use. You can switch between three different Unison Modes by pressing its button. The first mode is Staccato, where envelopes retrigger with every note trigger. The second mode is Legato, where envelopes retrigger only when all keys have been released. The last mode is Mono Mode, disabling polyphony and allocating all voices to the same note.
