Hi.
i have downloaded the GA4 demo, and played/programmed some acoustic drums with the keyboard, but find it is lack mostly snare articulations, for example, to make roll or marching alike snare its hard with only one key,and un natural, need the left hand (stick) struck as well on other key(maybe its there and i have missed it??) and maybe some samples of rolls and grace notes (for jazz easier programming for example)
this apply for other instruments on the kit as well (Kick, toms etc )
also it would be nice to mesh-up/build and share snare, kick etc from all acoustic kits
