I do 90% of my songwriting and recording in February every year as part of the February Album Writing Month; where the challenge is to write 14 songs in the month of February. I also usually record a demo of the song. I take 4-6 to do the recordigs.

In this regard, I've found EZ Drummer to be an insanely good solution as a songwriter. I end up with drums that have not caused me more than 10-15 minutes of work to lay out the song structure (intro, verses, choruses, pre-chorus, outro).

I don't do any particular processing on the drum tracks. I use a DAW template for a delay and reverb send/returns, and I'll send the drums to those and maybe play with the send level, but that's about it.

Here's some stuff from the past 2 years where I'm quite happy with the drum sounds - I will let others decide whether or not they are 'pro sound'. I don't know if these sound better or worse than BIAB. But since I play everything in my songs, besides drums, I may be partial to this 'drummer in a box' type thing that EZ Drummer allows me with very little effort.
