ofxMidi problem

Venetian · October 14, 2010, 6:41pm

Hi,

I’m trying to combine an app that uses ofxMidi and data from an arduino serial port - ofSerial.

I have an error message even if using a simple ofxMidiOut myMidiOut; declaration in the header.

However, the ofxMidi example works fine on its own.

is this to do with MIDI being serial data?

I saw this thread:
http://forum.openframeworks.cc/t/ofserial-and-midi-macosx/112/1

Thanks
Andrew

I have tried including Midi in another simple audioOutputExample and get the same error, so could this be something I’m doing wrong with setting up the ofxMidi library?

you need to include the CoreMidi framework in your project for ofxMidi to link without problem. Right click on the frameworks folder and select add framework, then select CoreMidi.

i’m not on osx right now so the names of the folders/menus can be a little different

Thanks!! That works great

I’m looking to also send a pitch bend message with midiout. Is that possible with ofxMidi?

Venetian · November 2, 2010, 10:39am

To follow up here.

This code should extend ofxMidiOut to send pitch bend messages (you also declare the function in the header file). It uses a similar method to those for note on off and control change

void ofxMidiOut::sendPitchBend(int channel, int value){
//value is 14bite resolution, coarse and fine
//neutral (no pitch bend relative to concert pitch) is a value of 8192
//value is 128 x 128 hence we calculate the two bytes to send with the following code

char byte1, byte2;
byte2 = value%128;
byte2 = (value - byte2)/128;
message.clear();
message.push_back( MIDI_PITCH_BEND+(channel-1) );
message.push_back( byte1 );
message.push_back( byte2 );
sendMessage();
}
