Studio One 3 - Bounce MIDI to Audio From a Hardware Keyboard/Synthesizer in Studio One 3. – Knowledge Base | PreSonus

In Studio One 3, when working with MIDI data, users often want to print the audio being generated by external MIDI devices to audio. Studio One offers a special feature to accommodate this.

The option "Bounce Selected" renders the selected Instrument Part to a new Audio Event, and places it at the correct Timeline position on a new Audio Track.

You will need to have the proper audio connections setup from your MIDI device to your audio interface. See Audio Device Setup: Studio One 3.

To bounce any MIDI Instrument Part to an Audio Track:

Select the MIDI Instrument Part.
Right-click and either select Bounce Selection in the Event menu, or simply press [Ctrl]+[B] or [Cmd]+[B] OS X on the computer keyboard.

When "Bounce Selection" is selected, an Audio Track will be inserted (A), and the Bounce Instrument Parts window appears. The Bounce Instrument Parts window shows the options for this bounce.

Here are definitions for the options in the Bounce Instrument Parts window.

B. Track Name: Use this option to name the track that will be created from the bounce.

C. Device Name: This is set to the name of the external MIDI device the MIDI Instrument Part is sending MIDI to.

D. Record Input: Use this drop down to select the audio input source for the Bounce.

E. Record Level: The Record Level shows the peak of the incoming audio signal. This level is controlled from by the hardware volume of the external MIDI device, or using the hardware volume on your audio interface.

F. Controls: In the Control section, there is a Stop and Play button. Use Play to preview the bounce.

G. Bounce Track: Starts the Bounce for the selected track.
