I have another, related question. Rendering to MP3 results in a much smaller file than .wav. Personally, I find MP3's generally to be perfectly acceptible in terms of sound quality. (Let's not debate that, to each her own, sounds fine to me.)

But is there any danger, in using a "lossy" rendering format like MP3 for backing tracks, that artifacts or missing sounds might hamper my recordings, to a greater degree than I actually HEAR in regular MP3's, (which starting at 160-192k sound "cd quality" to my ears.)

OR- is it true, as I hope it is, that if MP3 sounds good to me, then no reason not to go for smaller files and use it for backing tracks...?

Hope my question is clear. For home demo's, any reason NOT to use MP3?
