Self build Midi Controller

[DjNecro]

Heh, the 'cryptic' nature of that code is mostly due to the direct port manipulation... it's faster and more efficient than using digitalWrite(). and based on your code example, its actually exactly the same... I'm using the shortform of an if statement to safe some lines... it would normally look somthing similar to PORTD = 0b11101010, etc...

Btw.: Did you ever used a rotary encoder for midi controlling?

So far above my head, I couldn't hear the rumble from it's sonic boom.

Yep, I have two in my current controller, though one has been removed so I can beta test these: http://www.djtechtools.com/forum/showthread.php?t=25088

They're fairly simple to work with...

Again, this is C, not bascom... but the idea is the same...

byte read_two_encoders() {
  int8_t enc_states[] = {0,-1,1,0,1,0,0,-1,-1,0,0,1,0,1,-1,0};
  static uint8_t old_AB1, old_AB2 = 0;
  byte rtn = 0;

  old_AB1 <<= 2; //remember previous state
  old_AB1 |= (ENC_PORT & 0b11); //add current state
  old_AB2 <<= 2; //remember previous state
  old_AB2 |= (ENC_PORT & 0b1100) >> 2; //add current state
  rtn |= (enc_states[(old_AB1 & 0b1111)]) & 0b11;
  return rtn | ((enc_states[(old_AB2 & 0b1111)]) & 0b11) << 2;
}

O.k. Thanks. I just have to buy an encoder and figure it out myself. Just one question: Do you use midi out to your controller to set for e.g. a LED, when play ist pressed?

Yep, I have my transport controller rigged with two beat lights and 11 leds to show the crossfader position (i'm not currently using it because the end of my midi chain doesn't have midi-in..

I've also done some work with these, things like using them as vu's or more recently pulsing beat lights using PWM...
