Has anyone had any luck of getting real time MIDI to work with seedstudio music shield v1? It's based on VC1053B.
Ok I figured it out. MIDI works just fine...
Musicplayer.cpp (from Music_shield library) has function midiDemoPlayer() which can play notes, change banks, etc.
It was just a matter of moving midi functions from private to public in MusicPlayer.h file and then calling them from your sketch...
For example:
player.beginInMidiFmt();
player.midiWriteData(0xB0, 0x07, 120); // Set MIDI channel volume
player.midiWriteData(0xB0, 0, 0x00); // Select bank GM1
player.midiWriteData(0xC0, 1, 0); // Select instrument (Piano)
player.midiNoteOn(0, 70, 127); // Play note (C4)
delay (1000);
player.midiNoteOff(0, 70, 127); // Stop playing note
Hi bratan, do you have a copy of your edited MusicPlayer.h? Can you share it with the group.
Thanks muchs

Sure here it is...
MusicPlayer.h (7.42 KB)
Thanks much
Does your mididemoplayer code look like this?
#include <SD.h>
#include <SPI.h>
#include <Arduino.h>
#include <MusicPlayer.h>
void setup(void)
{
Serial.begin(9600);
player.beginInMidiFmt();
}
void loop(void)
{
player.midiDemoPlayer();
}
delay(500);
}
because even with the modified musicplayer.h I couldn't get this to work.
I can't get my vs1053 shield to work in Midi mode. I'm using arduino Arduino uno and mega (either one). Can you help me?
I haven't played with it for a long time. I think this sketch should work if you connected all the pins correctly. It will just play middle C note.
#include <SD.h>
#include <SPI.h>
#include <MusicPlayer.h>
void setup()
{
Serial.begin(115200);
midiInit();
//player.midiWriteData(0xC0, 1, 0); // Select instrument
middleC();
//triggerNotes();
// playMIDIMelody();
}
void loop()
{
//player.play();
//delay(500);
}
void triggerNotes() {
for (int note = 30; note <87; note++) {
player.midiNoteOn(0, note, 127);
delay (50);
player.midiNoteOff(0, note, 127);
delay (50);
}
}
// Play one note for all instruments in bank GM1
void middleC(){
setMIDIBank (1);
for (int i=0;i<127;i++) {
Serial.print ("Playing instrument: ");
Serial.println (i);
player.midiWriteData(0xC0, i, 0); // Select instrument
player.midiNoteOn(0, 60, 127); // Play C4
delay (1000);
player.midiNoteOff(0, 60, 127); // Stop playing C4
}
}
void playMIDIMelody () {
// Note numbers
int C4=60,D4=62,E4=64,F4=65,G4=67,A4=69,B4=71,C5=72;
int PP=0; //Pause
int melody[] = {C4,C4,PP,G4,G4,PP,A4,A4,PP,G4,PP,PP,PP,PP,
F4,F4,PP,E4,E4,PP,D4,D4,PP,C4};
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = { 8,8,8,8,8,4,
8,8,8,8,8,4,
8,8,8,8,8,4,
8,8,8,8,8,4,
8,8,8,8,8,4};
player.midiWriteData(0xC0, 1, 0); // Select instrument
for (int thisNote = 0; thisNote < 24; thisNote++) {
if (melody[thisNote]==PP) // Pause
delay (50);
else {
player.midiNoteOn(0, melody[thisNote], 127);
delay (250);
player.midiNoteOff(0, melody[thisNote], 127);
Serial.println (melody[thisNote]);
// to distinguish the notes, set a minimum time between them.
// the note's duration + 30% seems to work well:
delay (200);
}
}
}
// Initializes MIDI
void midiInit(){
player.beginInMidiFmt();
player.midiWriteData(0xB0, 0x07, 120); // Set MIDI channel volume
}
// Sets MIDI bank to GM1 or GM2. Takes values 1 or 2
void setMIDIBank(byte bank) {
if (bank==1) player.midiWriteData(0xB0, 0, 0x00); // Select bank GM1
else player.midiWriteData(0xB0, 0, 0x78); // Select bank GM2
}
I tried it, but didn't hear any tone.
Looking in Pin_config.h I see
//////////////////////for vs10xx///////////////////////////////////
#define VS_XRESET A0
#define VS_DREQ A1
#define VS_XDCS A2
#define VS_XCS A3
which looks incorrect to me, my shield has
X_RESET D8
DREQ D2
XDCS D7
XCS D6
CS D9
Should I go ahead and edit those defines?
Horray! Finally I hear some tones. 
Thanks much Braton
changes defines in pin_config.h to
//////////////////////for vs10xx///////////////////////////////////
#define VS_XRESET 8
#define VS_DREQ 2
#define VS_XDCS 7
#define VS_XCS 6
Glad you got it working!
