mci & midi questions

[Leston Drake]

I need some help.

I'm trying to add some 'background' music to an application and I would 
like to use MIDI (small files are good).
In MetaCard (on Windows) you use the mciSendString() function to send 
commands to the Windows system, and this is fine, except that I need a 
comprehensive list of commands.

Specifically, I need to periodically query the device to know when it has 
reached the end, so I can restart it.
There is a STATUS command for MCI, but it doesn't seem to work with the 
MIDI SEQUENCER device. If it does, I have no idea what the valid parameters 
are. The example for STATUS in the MCI.MC file available from MetaCard's 
website doesn't work either, it is lacking a (vital) parameter.

Does anyone know of a comprehensive list of MCI Commands?

Related question that I will need to address - is there any way to 
*natively* play MIDI on Mac?

TIA,
Leston
