The CD Support included in Bass is very basic, you can only have one drive playing at a time. Basically what bass does is control the playback only, you cannot get the data from the cd using bass, or levels. Ian is currently working on a CD Streaming add-on, which will play cds digitally, meaning that you will be able to retrieve data off the CD and visualize or do with it what you want (i.e. Rip the CD into WAV)
