You can automate pitch in Omnisphere using a combination of features like MIDI controllers, automation lanes, modulation sources, and macros.
Using MIDI Controllers
- Pitch Bend Wheel: The most common method is to use a pitch bend wheel on your MIDI keyboard. Assign the pitch bend wheel to control the Pitch parameter in Omnisphere's Modulation Matrix. This allows you to bend the pitch in real-time.
- Aftertouch: Some MIDI controllers feature aftertouch, which lets you control the pitch based on how hard you press a key. Map this to the Pitch parameter in the Modulation Matrix for dynamic pitch control.
Using Automation Lanes
- Draw Automation: You can draw automation curves in Omnisphere's automation lanes to control the pitch of a sound over time. This gives you precise control over pitch changes and allows you to create complex melodic lines.
- MIDI CC Automation: You can automate MIDI CC messages to control the pitch parameter. This method provides greater flexibility as you can use any MIDI CC message as a control source.
Using Modulation Sources
- LFOs: You can use low-frequency oscillators (LFOs) to modulate the pitch parameter, creating vibrato or other pitch-shifting effects.
- Envelopes: Envelopes can be used to create dynamic pitch changes over time. This allows you to create effects like pitch bends, portamento, or even pitch-based sound design elements.
Using Macros
- Macro Control: Omnisphere's macro system allows you to create custom controls for any parameter, including pitch. This makes it easy to automate pitch changes using a single knob or slider.
Example:
- Create a Macro: In Omnisphere, create a new macro and name it "Pitch Control".
- Assign Parameter: Assign the macro to the Pitch parameter in Omnisphere's Modulation Matrix.
- Map to Controller: Map the macro to a MIDI controller, such as a knob or slider on your keyboard.
- Automate Pitch: Now, you can move the controller to automate pitch changes in your sound.
Practical Insights
- Experiment: Try different methods and combinations to find the best approach for your specific needs.
- Modulation Matrix: The Modulation Matrix is a powerful tool for creating complex pitch automations.
- Macros: Macros can simplify automation tasks by providing a single control for multiple parameters.
