Like I said- your mileage may vary. I mixed in RB when I first started using it to check it out. Not only could I mix, but every single third party plugin showed up and worked well in RB- something that is not always the case in Reaper and other daws. But for me, there were things I could not deal with in RB. Can't even remember what exactly they all were, but one big one was the inability to manually advance the timeline by just clicking anywhere. Can't deal with that. But it's such a personal thing. You really have to make your own choices. The best part is that RB works in a number of ways, so it's not a bad thing at all. The way RB works can be proprietary in nature, so how you use it won't always carry over to the main stream daws. Learn one main stream daw, and you can get around all of them that much easier. But even considering that, proprietary software is nothing new and some of it is very much worth learning regardless. SAW software- another daw- is VERY good and worth learning it's proprietary ways. I sure did. The choice with all of this, is up to you. It's hard to go wrong really- in fact you can't, as far as the daw. They give you so much power, it's more likely YOU'LL be the one to get into trouble! LOL! Good luck.
