Alright, thanks! I appreciate your comments.
Do you hear any rumbling at 2:20?
Because I used timpani at 2:30 and throughout a lot of the piece.
Could the timpani be the cause of the rumble that you're hearing?
Or, it could probably just be the natural rumbling of the piano.
I really do hope it's not a problem with the piano,
because it's one of the best sampled (imo) pianos out there at the moment and I really like the sound of it personally.
Thanks.
