I've been using ReBirth and DM-1 for some drum tracks. I realized pretty quickly, using Audio Copy/Paste (ACP) and putting the drums on a single track is fairly limiting if you want complete control over your mix. I'd add some EQ and compression, but it effects the ENTIRE drum set, and I'm not able to get exactly what I want.
My plan was to turn on/off each drum part individually and ACP over to Auria.
The other day I realized DM-1 lets you export to Dropbox each individual drum part (WAV or AAC), which I can then import into Auria. So I tried it last night and placed all the individual parts on separate tracks and placed them into a subgroup. Now I can work on each drum part separately. This is fantastic! I did notice the CPU value took a jump after adding all of the tracks, but that is expected.
Thought I'd share this tip for those who may not know about it. ReBirth, unfortunately, does not have this feature.
