Don't draw notes before t_sent on timer, because they cannot change. Do not calculate everyting in every line: precalculate. Run profiler.
Make note highlighting, step highlighting and playback position drawing non-destructive for image (draw to multiple DCs and then combine).
Use a faster API.
Do not use alpha blending.
Redraw everything rarely.
