hello all,
i am messing with midi out, soon i will mess with midi in when i get my leds and everything else to test out what i need. but i am running into a weird problem with some code that i hooked up. sometimes when i start, say, live. it crash the whole computer when the arduino is plugged in to midi with a power cord to, well, power it. very strange.
obviously this has to be a code problem, i could not see any other reason why not. but cant see at the moment what it is that could be causing this.
just got a bit of a tired head on me at the moment.
this was made with code from a blog site that has been mentioned a few times, sorry i cant remember just now.
many thanks if you can help.

// command bytes
byte status_byte = 176; // control change on channel 1
byte cc_number = 0; // value for control number
// init transfer and operation values
byte data_send = 0; // stores outgoing byte for spi bus
// init looping and working values
int workPort = 0; // working value for outgoing port
int workAn = 0; // working value for analog input
// setup begins here

}
// main program begins here
void loop() {
for(int i = 0; i <= 15; i ++) // loop the following code 8 times
{
cc_number = 20 + i; // set control number to between 20 and 25 depending on loop iteration
workPort = (i / 2) * 4; // get pot 1 to 8 ignoring bits 0 and 1 of a 5 bit value
PORTD = workPort; // set pins 2, 3 and 4 to value between 0 (00000) and 7 (11100)
workAn = i % 2; // and read in either analog input 0 or 1 depending on the loop
data_send = analogRead(workAn) / 8; //read analog pin into variable... with 10 bit -> 7 bit
Serial.print(status_byte); // send status byte
Serial.print(cc_number); // send CC number
Serial.print(data_send); // send data value
// loop back...
}
// loop back...
