#need to study the code above cuz it comes from an example. goal is to get it to interface with the ddj sb3
#this looks like a good solution with mido... https://stackoverflow.com/questions/60182510/mido-how-to-get-midi-data-in-realtime-from-different-ports

#So the way shit works is that we receive Message stuff (https://mido.readthedocs.io/en/latest/message_types.html) and in it,different attributes. The ones we only
# care about are note_on events, and we only need to pay attention to: the note (tells which thing has been pressed, at least for our novation launchkey, might be different on the ddj-sb3)
# and the velocity to tell if a key is released or not. This complicates a little bit for dj controllers because we have jogwheels lmao, but we will figure this out.
#thers also control values, which go from 0 to 127, so with some maths for thresholds, we have.. item selectors and whatnots
# the velocity is great for detecting pads, which should be the buttons of a controller. if we can simulate a button being held, we are gucci
#the vgamepad library actually may allow this directly due to how it updates stuff... might have to try it out, and play with timings when doing midi->xinput
