The different types of modulation available are vibrato, tremolo and chorus. See the preset descriptions for modulation type.Click KnobClick controls percussive click level. It was designed to simulate the harmonic percussion effect on classic B3 and C3 organs. The click is added to the very first note or chord played. The click will re-trigger only when current notes have been released and their amplitude falls below a threshold. For most presets, Click controls parameters unique to the preset. See the preset descriptions for details.
