C++ Midi Play Multiple Voices Simultaneosly

Write a basic MSVC 6.0 C++ console program that will Play Multiple (3 or more) Midi Voices Simultaneosly. Note that a playing a midi chord (Multiple notes) with the same voice (instrument) is trivial and requires no delay between each midiOutShortMsg as follows: /* Output the C note (ie, sound the note) */ midiOutShortMsg(handle, 0x00403C90); /* Output the E note */ midiOutShortMsg(handle, 0x00404090); /* Output the G note */ midiOutShortMsg(handle, 0x00404390); /* insert a delay so that you can hear the notes sounding */ Sleep(3000); // listen for 3 seconds The problem is that changing the Voice with midiOutShortMsg each seems to need roughly 100ms delay between each midiOutShortMsg otherwise all 3 voices are not heard.
