Not trying to dissuade anyone from using/learning RealBand - it is astounding to think that with BIAB, you also get a full-blown DAW...

But... I believe Dani has been using Mixcraft (and doing a fine job!) and from what I have seen, it seems like a nice DAW (especially for the price)... https://www.youtube.com/watch?v=fJPe1DwXPuE

It has volume envelopes (automation) - so my question is... why not use that to get the drum levels sounding even...

Learning a new DAW can be a daunting task - I recently switched from Sony Acid Pro to Presonus Studio One (Pro). It took several full-blown productions to get comfortable (I am really liking it, btw! - highly recommend it)...
