hello, im new in this forum, and for the first project i tried a midi controller (5 butttons for midi out / 5x program change)
it worked for the first go, but i have to press the buttons several times before the midi out signal changes the program ??
i'm thankful for all ideas!
code below:
// Constants
#define SWITCH1 2
#define SWITCH2 3
#define SWITCH3 4
#define SWITCH4 5
#define SWITCH5 6
#define LED1 7
#define LED2 8
#define LED3 9
#define LED4 10
#define LED5 11
#define BOUNCEDELAY 100
// Variables:
int switches[5] = { SWITCH1, SWITCH2, SWITCH3, SWITCH4, SWITCH5 };
int switchState[5] = { HIGH, HIGH, HIGH, HIGH, HIGH };
// Initial state of switch is high due to internal pullup
int leds[5] = { LED1, LED2, LED3, LED4, LED5 };
int currentSwitch = 0;
int currentProgram = 00; // current program - sent to the output
int pedalActiveFlash = 250; // Delay for flash when pedal is pressed
void setup() {
// Set MIDI baud rate:
Serial.begin(31250);
// Setup Switches and activation LEDs
for( currentSwitch = 0; currentSwitch < 5; currentSwitch++ ) {
pinMode( switches[currentSwitch], INPUT ); // Set pin for switch
digitalWrite( switches[currentSwitch], HIGH ); // Turn on internal pullup
pinMode( leds[currentSwitch], OUTPUT ); // Set pin for LED
flashPin( leds[currentSwitch], 250 ); // Flash LED
}
}
void loop() {
for( currentSwitch = 0; currentSwitch < 5; currentSwitch++ ) {
if((digitalRead(switches[currentSwitch]) != switchState[currentSwitch] )&&(switchState[currentSwitch] == HIGH)){
switch( currentSwitch ) {
case 0:
// Favourite 1
currentProgram = 00;
midiProg( 0xC0, currentProgram );
flashPin( leds[currentSwitch], pedalActiveFlash );
break;
case 1:
// Favourite 2
currentProgram = 01;
midiProg( 0xC0, currentProgram );
flashPin( leds[currentSwitch], pedalActiveFlash );
break;
case 2:
// Favourite 3
currentProgram = 02;
midiProg( 0xC0, currentProgram );
flashPin( leds[currentSwitch], pedalActiveFlash );
break;
case 3:
// Favourite 4
currentProgram = 03;
midiProg( 0xC0, currentProgram );
flashPin( leds[currentSwitch], pedalActiveFlash );
break;
case 4:
// Favourite 5
currentProgram = 04;
midiProg( 0xC0, currentProgram );
flashPin( leds[currentSwitch], pedalActiveFlash );
break;
}
delay( BOUNCEDELAY );
}
switchState[currentSwitch] = digitalRead( switches[currentSwitch] );
}
}
// Send a three byte midi message
void midiSend(char status, char data1, char data2) {
Serial.print(status, BYTE);
Serial.print(data1, BYTE);
Serial.print(data2, BYTE);
}
// Send a two byte midi message
void midiProg(char status, int data ) {
Serial.print(status, BYTE);
Serial.print(data, BYTE);
}
void flashPin( int ledPin, int flashDelay ) {
digitalWrite( ledPin, HIGH );
delay( flashDelay );
digitalWrite( ledPin, LOW );
}
