Control
The Control section contains a few options that affect how OB-Xf responds to certain incoming MIDI data.
Pitch Bend
Section titled “Pitch Bend”- Down and Up: These menus set the pitch bend amount in semitones, from 0 to 48, separately for positive and negative values of MIDI Pitch Bend messages.
- Osc 2 Only: Toggling this button makes the pitch bend wheel affect only Oscillator 2. This can be very useful for hard sync sounds.
Vibrato
Section titled “Vibrato”This is a dedicated global LFO that modulates the pitch of both oscillators across all voices simultaneously. Vibrato amount is controlled by the modulation wheel (MIDI CC #1).
- Rate: Sets the speed of the vibrato LFO.
- Shape: Sets the LFO waveform to a triangle or a unipolar square.
