I would like to see an option to change between pump per beat and single stroke. Both have their up and downsides for the different types of note maps. (Handy btw)
Pump per beat works more for songs with more space in between/less notes, more stimulation for less. On the flip side a big problem is that it can get stalled during spam notes where it will then do all of the missed note's pumps full speed until the debt is paid. And with how it is currently implemented it doesn't have a very long length of travel and only the down is in sync with the notes unless they're spaced just right.
However, the single stroke doesn't have the stalling issue. I'm assuming that (and I have no clue how any of this works) It just overrides the stroke when a new note is pressed, but with the pump it becomes an issue because it is two strokes and is maybe not overriding the old notes and only queues them. The single also has full length of travel on the handy.
So, I just think that they're too different to be locked into one or the other.
