Sending Pitchbend from a Slider or Dial1
This project demonstrates how to use a Loopy Pro slider plus the Mozaic or Streambyter MIDI AUv3 to create a pitchbend slider or pitch wheel. The project uses a slider but a dial could be set up identically.

The project's slider has a Value Change action that adjusts a parameter in Mozaic or Streambyter which are set to send out pitchbend. When the slider is released, Mozaic or Streambyter reset the pitchbend.
