11. Setting up the mod wheel to control vibrato

1 The modulation wheel’s traditional use is for adding vibrato to a sound by increasing an LFO’s depth of control over oscillator pitch – but it can be used for other things, such as adjusting filter cutoff. In our example, Bazille CM’s Init default sound has no parameters assigned to the mod wheel, so moving the wheel has no effect on the sound.

2 Let’s set it up to control vibrato. Vibrato is achieved by using one of the synth’s LFOs (low frequency oscillators) to modulate the pitch of the main oscillators. The Mod wheel is already linked to LFO Depth, indicated by the orange text field below the Amp Mod control in the LFO 1 section – we just need to turn the control up to the max.

3 The target for the modulation will be the pitch of oscillator 1, so we draw a virtual cable between the LFO’s output and the Freq Mod Depth control ( PM Coarse) in the Osc 1 panel. Turn this control fully right, then select Cents from the 50 Semi menu. Moving the wheel introduces vibrato, the speed of which is controlled by LFO1’s Rate control.
