EVOC 20 PS pitch modulation in Logic Pro for iPad
EVOC 20 PS includes an LFO that is dedicated to pitch modulation (vibrato). It can either run freely or can be synchronized with the project tempo.
Synthesizer Pitch Modulation parameters
LFO Rate knob and field: Set the speed of modulation. Values to the left (of the centered position) are synchronized with the host application tempo. These include bar values, triplet values, and so on. Values to the right (of the centered position) are nonsynchronized, and are displayed in hertz—cycles per second.
LFO Waveform pop-up menu: Set the waveform type used for vibrato (pitch modulation). You can choose from the following waveforms:
Triangle
Falling and rising sawtooth
Square up and down around zero (bipolar, good for trills)
Square up from zero (unipolar, good for changing between two definable pitches)
Random stepped waveform (S & H)
Smoothed random waveform
Min/Max Vibrato sliders and fields: Set the intensity of LFO pitch modulation. The Max Vibrato slider determines the intensity when the modulation wheel is set to its maximum value; the Min Vibrato slider determines the intensity when the modulation wheel is set to its minimum value. This parameter is permanently assigned to the modulation wheel of your MIDI keyboard, or corresponding MIDI data.
