  • processing arduino library & serial library problem when used with midiBus library
    Hey guy's -- I am getting a really annoying error that keeps happening when using the arduino library along with the midi library -- here it is:

    anyone else run into this problem?? any ideas on how to stop this error from happening?? I have arduino.serialWrite functions being called when midi data is being read -- is this the problem??
