iím trying to build a fast, jitter-free MIDI to DMX box. i made one following this: https://imgur.com/a/vhwt9
and it works, but itís a bit laggy.

since i had a teensy 3.5 laying around, i thought iíd give it a go, and when i tried a basic midi receive example program:

Code:
int ledPin = 13;

void OnNoteOn(byte channel, byte note, byte velocity) {
  digitalWrite(ledPin, HIGH); // Any Note-On turns on LED
}

void OnNoteOff(byte channel, byte note, byte velocity) {
  digitalWrite(ledPin, LOW);  // Any Note-Off turns off LED
}

void setup() {
  pinMode(ledPin, OUTPUT);
  usbMIDI.setHandleNoteOff(OnNoteOff);
  usbMIDI.setHandleNoteOn(OnNoteOn);
  digitalWrite(ledPin, HIGH);
  delay(400);                 // Blink LED once at startup
  digitalWrite(ledPin, LOW);
}

void loop() {
  usbMIDI.read(5);
}
it proved to be way more responsive, at least visually (LED flashing).

iím a newbie and iím struggling to get the hang of Shawn Silvermanís examples in the TeensyDMX library. i wanted to use midi noteOn data from the example above be sent to one DMX channel, which seems rather simple, but i insist: iím a total noob, so not so easy for me.

if anybody could give me any pointers on how to do this, perhaps using the basic send example in the TeensyDMX library (see code below), as i assume is the most basic one? BUT equally important, i need some pointers on hardware, cause i may have missed the info in the library files, and this may be a very silly question, but: how do i make these DMX messages go out via a DMX/XLR cable from my Teensy 3.5??? i read it goes over serial pins, but any example diagrams out there?

MANY MANY THANKS!!!

  // Do something, maybe alter channel values.
