MIDIs

Few short questions about MIDIs in VB:

1) How to play/stop/pause a MIDI? (an example or link to one would be nice if possible)

2) How to play more than one MIDI at the same time?

3) How to detect if a MIDI has stopped playing? (to start it again so it goes on repeating)

Any help is appreciated and, of cource, welcome!
