Hello,
Im trying to create a midi foot switch to control my AXE FX II unit (http://wiki.fractalaudio.com/index.php?title=MIDI is the MIDI CC messages). This is the schematic I'm using is attached.
This is the code:
#include <MIDI.h>
#include <midi_Defs.h>
#include <midi_Namespace.h>
#include <midi_Settings.h>
#include <Button.h>
int ledPin = 13; //choose the pin for the LED - needs to be (3,5,6,9,10, or 11)
int buttonPin = 2; //choose the input pin for a pushbutton
int buttonVal = 0; //variable for reading the button status
int buttonState = 0; //variable to hold the buttons current state
int bounceCheck = 0; //variable for debouncing
void setup() {
pinMode(ledPin, OUTPUT); //declare LED as output
pinMode(buttonPin, INPUT); //declare pushbutton as input
Serial.begin(31250); //MIDI communicates at 31250 baud
}
void loop(){
buttonVal = digitalRead(buttonPin); //read input value from button
delay(10); //wait 10ms
bounceCheck = digitalRead(buttonPin); //check again
if(buttonVal == bounceCheck){ //if val is the same then not a bounce
if (buttonVal == HIGH && buttonState == 1) { //check if the input is HIGH
digitalWrite(ledPin, LOW); //turn LED OFF
MIDI.sendNoteOff(60,0,1);
buttonState = 0;
}
if(buttonVal == LOW && buttonState == 0){
digitalWrite(ledPin, HIGH); //turn LED ON
MIDI.sendNoteOn(60,127,1);
buttonState = 1;
}
}
}
void midiOUT(char command, char value1, char value2) {
Serial.write(command);
Serial.write(value1);
Serial.write(value2);
}
}
I've tried changing the numbers on the "MIDI.sendNoteOn(60,127,1);" and still nothing is changing. Can someone guide me which command should be sent to at least do one function?
Image is too big, please resize it.
Are you able to send any midi message?
You don't need the midiOUT function since you're using the midi library
Go slowly, get rid of the button part and just send a midi note with a delay of 500 or so. How are you monitoring the output? The best would be to use a computer with any midi monitor, like midi-ox.
Maybe your connection is wrong, sometimes it's hard to tell which pin is 4 and 5 on the midi connector.
Which command from the MIDI library would be suitable for the MIDI CC wiki page I posted? I connected directly to my AXE FX unit, and I keep uploading with different numbers to see if anything happens.
Thank you very much for the support, I'm nearly there. Using hairless midi, I found out that my old code used to send notes, thats why probably it wasnt working. But when I replaced the sender with the MIDI library function, for some reason nothing is being sent on the serial or captured by the hairless midi....

int buttonState = 0; //variable to hold the buttons current state

void setup() {
MIDI.begin(0);
pinMode(ledPin, OUTPUT); //declare LED as output
pinMode(buttonPin, INPUT); //declare pushbutton as input
Serial.begin(31250); //MIDI communicates at 31250 baud
}
void loop(){
buttonVal = digitalRead(buttonPin); //read input value from button
delay(10); //wait 10ms
bounceCheck = digitalRead(buttonPin); //check again
if(buttonVal == bounceCheck){ //if val is the same then not a bounce
if (buttonVal == HIGH && buttonState == 1) { //check if the input is HIGH
digitalWrite(ledPin, LOW); //turn LED OFF
MIDI.sendControlChange(1, 120, 1);
buttonState = 0;
}
if(buttonVal == LOW && buttonState == 0){
digitalWrite(ledPin, HIGH); //turn LED ON
MIDI.sendControlChange(1, 10, 1);
buttonState = 1;
}
}
}
Which one is your old working code? The first one?
By the way, MIDI.begin(0) is wrong, it should be 1-16, or nothing. It shouldn't affect your code though.
