So, mein Controller ist jetzt fertig! Er besteht aus 32 Potis und 64 Tastern mit zugehörigen LEDs. Ich habe nun das MIOS und mein Programm erfolgreich installiert. Die Potis funktionieren einwandfrei, allerdings habe ich ein Problem mit den Tastern und den LEDs: Bei Druck auf die Taster passiert erst einmal gar nichts... Ich empfange weder ein Midi-Signal, noch wird irgendeine LED aktiviert. Wenn ich viele Taster hintereinander betätige, werden plötzlich alle Aktivierungen per Midi auf einmal übertragen (Aufstauung der Befehle??). Die LEDs werden immer noch nicht gesetzt. Was mir leider erst im Nachhinein aufgefallen ist: Ich habe Taster in Schalterform verbaut (Aktivierung -> Wechsel der Spannung, beim Loslassen allerdings nicht zurück). Das sollte technisch gesehen allerdings kein Problem sein, oder? Die Funktion "DIN_NotifyToggle" sollte ja trotzdem aufgerufen werden. Ich habe nochmal alles mit einem Multimeter ausgemessen. Die Buttons reagieren einwandfrei... mittlerweile komme ich nicht mehr weiter mit diesem Problem:( Über Hilfe würde ich mich sehr freuen!! Ich sende nochmal meinen gesamten C-Quellcode mit, vielleicht steckt da ja der Wurm drin /*
