Hi folks. Discovered Typos in Teensy>Examples>USB_MIDI>TransmitEverything.

IDE 1.8.9 TD1.47, From line 143:-

Code:
case 21:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendRpnValue(6489, channel, cable);
      usbMIDI.endRpn(channel, cable);
      break;
    case 22:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendRpnIncrement(3, channel, cable);
      usbMIDI.endRpn(channel, cable);
      break;
    case 23:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendRpnDecrement(2, channel, cable);
      usbMIDI.endRpn(channel, cable);
      break;
Should be:-

Code:
case 21:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendNrpnValue(6489, channel, cable);
      usbMIDI.endNrpn(channel, cable);
      break;
    case 22:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendNrpnIncrement(3, channel, cable);
      usbMIDI.endNrpn(channel, cable);
      break;
    case 23:
      usbMIDI.beginNrpn(417, channel, cable);
      usbMIDI.sendNrpnDecrement(2, channel, cable);
      usbMIDI.endNrpn(channel, cable);
      break;
Thanks everyone for Teensy. Totally awesome! Cheers.
