    n = i
    break
else:
  print(f"Couldn't find M32 port")
def cb(e,x):
  data,t = e
  print(data,t)
midiin.set_callback(cb)
midiin.open_port(n)

from rtmidi import RtMidiIn
pat = "M32"
midiin = RtMidiIn()
for i in range(midiin.getPortCount()):
  name = midiin.getPortName(name)
  if pat in name:
    midiin.openPort(i)
    break
else:
  print(f"Didn't find port with name containing {pat}")
  exit(1)
def cb(*xs,**kw):
  print(xs,kw)
midiin.setCallback(cb)
# and then press keys and turn knobs
