Hi,
After reading this thread, I purchased the paid version.
As a life-long drummer, the first thing I noticed, is on the Rock Kit, the tom above the snare is out of sequence with the next tom (to it's right side). A typical generic 5 pc kit (for right handed players), typically has the higher pitched tom above the snare on the left (typically a 12 inch tom), the next tom over to the right (above the bass kick drum) is usually a 13 inch tom, and the floor tom is usually to the far right. Everything seems to be in order, except for the sequence of the toms above the bass drum (kick).
I really do like the tones of the rock kit. They sound pretty authentic.
My only other suggestion would be, if there were a way to export/record patterns, that would be fantastic!
Cheers,
Gabe
