Clearly Groove Agent’s main strength is the incredibly well working Beat Agent workflow, which is miles ahead of everything I ever had from Maschine or Battery within Cubase. And the Media bay is a wonderful and very essential part of that first class workflow to me.
But if your main goal is acoustic drumming, the useable, but not overwhelming Acoustic Agent is not for you: as long as you can’t replace drum kit elements and have more control, it rather is an easy way of having some acoustic kits available than an overall acoustic drum solution.
So why don’t you use Superior Drummer or the likes for acoustic drumming instead, well knowing that it is made for your kind of acoustic drum set demands, instead of getting desperate with Groove Agents acoustic setup?
