Q: tips on getting nice snare rolls on midi drums? is it just a sound that certain instruments have or is it an arpeggiator trick?
A: your best bet for that would be to use some good samples, and then you can take control of the pitch, eq, etc and make it your own, and also of course tightly control the duration. and also have a wide variety of choices. the more options you can get in front of you, (different samples, different pitch, etc) the more likely you are to reach for that right one at the right time
