This video shows the two vibrato controlled by different modulators. It is a way to automate Mod Wheel or to alternate between “normal” and “FM” sounds with the same oscillator. Mod Wheel is still available on both LFOs at the same time as the modulated intensity.
KrOn 3 is a free update to KrOn and is available right now in your user area.
It adds a dual vibrato that can be automated, as well as Hz controlled LFOs, in addition to important corrections to presets.
