Gig Performer includes a built-in recording feature that allows you to capture not only audio arriving at your audio interface's inputs, before it has passed through any of the plugins, but also outputs and all incoming MIDI messages.
By capturing the audio and saving your gig, you can replicate the performance and modify it in post-production. To access the Recorder, just click the Recorder button in the bottom toolbar:
Files are recorded in WAV format. Each time you start the recorder, a subfolder is created within the (master) recording folder and named with the date of the recording (see the File locations in Gig Performer chapter for more information about default locations in Gig Performer). All files from your recording are placed within that subfolder. This makes it very easy to organize recordings made at different performances during a tour.
