rtmidi problem after running the code x times

[philipbergwerf]

I found the solution to this problem. I made a variable 'midiswitch' that is standard set to 1 and when the program closes it is set to 0. The while loop checks if the variable is 0 and closes the loop if so.

def midi_input():

    class Collector(threading.Thread):
        def __init__(self, device, port):
            threading.Thread.__init__(self)
            self.setDaemon(True)
            self.port = port
            self.portName = device.getPortName(port)
            self.device = device
            self.quit = False

        def run(self):
            self.device.openPort(self.port)
            self.device.ignoreTypes(True, False, True)
            while True:
                if midiswitch == 0:
                    return
                msg = self.device.getMessage(2500)
                if msg:
                    if msg.isNoteOn():
                        if midi_record_toggle == 1:
                            note = msg.getNoteNumber() - 20
                            if shiftkey == 0:
                                textw.insert(textw.index(INSERT), number2pitch[note])
                            elif shiftkey == 1:
                                textw.insert(textw.index(INSERT), '_'+number2pitch[note])
                            renderkey()

    dev = rtmidi.RtMidiIn()
    for i in range(dev.getPortCount()):
        device = rtmidi.RtMidiIn()
        print('OPENING',dev.getPortName(i))
        collector = Collector(device, i)
        collector.start()

threading.Thread(target=midi_input).start()
