With the vertical track scrolling I move the mouse wheel up/down a few times then go and get a cup of coffee when I come back it's still going up and down by it's self with the cpu usage on 95%.
Do you need to have all 48 tracks in there when you don't use them ?
maybe if you have an Add Track, Delete Track so you don't need it to scroll so many tracks and all the track bmp images, maybe do away with the bmp track images ?
Be able to drag a track up/down to change it's position.
