Recording
The freebees demo project is prepared for bounce recording. The wave files are initially empty (to minimize download size of Podium installer) so you have to bounce record to create the wave files. Assuming that you have the plugins installed; enter into one of the songs. Turn off looping and switch on the record button. The tracks containing the bounce audio events should be red now. Start playback. The audio should now be rendered into the audio events as playback progresses.
Once you have recorded the entire song, switch off the ‘R’ (record enable) track buttons for the bounce tracks. This will enable the bounced audio and the plugins will become inactive. You can then use the ‘B’ (bounce) track button to switch between listening to the bounced audio or reactivate the plugin output.
