Midi program changes in ProcessMidi function of WDL-OL

[aaron_baker]

Hello!

I'm working on a MIDI vst instrument using WDL-OL, but understanding is a little difficult, more MIDI's fault than WDL-OL's.

Some how, this code retrieves the channel.

int event = pMsg->mStatus >> 4;
int channel = pMsg->mStatus & 0x0F;

I would like to retrieve program changes so that I can play, for example, different synths on different programs. Some plugins will change the presets when the programs are changed, which is a neat idea.

Any help would be appreciated!

If you can tell me some further reading matterial regarding WDL-OL and MIDI, that would also be highly appreciated!

Best,
Aaron
