Open or create a QuickScore file or a MIDI file.
Make sure youve loaded one or more VST instruments with suitable effects and they are selected for playback in the Track Sheet. See How to use VST Instruments for details on doing this.
In the Audio Mixer, click on Export in the master strip to activate exporting audio. When Export in the master strip is active, any audio sent through the master strip of the Audio Mixer when playing or recording will be saved to a Wave file or an MP3 file. The Save Audio dialog appears.
Choose Save All to save all the audio or choose Save between times to only save audio that occurs between a start and end time that you specify. Click on the Browse button to choose a Wave or Mp3 file to which your audio will be saved. The number of channels in the file saved will be the same as the number of channels of audio passing through the master strip.
Specify the resolution (or sample size) and sample rate for the saved audio file.
Click OK. Now play your song from the beginning. When you are finished, an audio file with the name you specified will be created for your song.
