Glide—also known as portamento—and Autobend are hardwired to control oscillator pitch. See
The Analog, Sync, and Wavetable oscillator waveform shapes can be modulated by following these steps. In the FM synth engine, you can modulate the FM or Harmonic amount (or both).
In Logic Pro, move the control toward LFO or Filter Env. Positions further away from the centered (off) position make waveform modulation more intense.
Adjust the controls of the LFO (click the LFO tab if the Vibrato pane is visible) and Filter Env sections. See decay, PDF
