Yeah DMP's CPU meter is measuring DMP's CPU usage which can differ a bit
from what happens when playing through "the real DMusic API". If you
play through my DMDemo app and check Task Manager you will get a more
accurate reading. The RAM usage is always going to be wrong since apps
always take memory. With DMDemo you have to subtract like 5-6 MB for
the app, I don't know what the number is for DMP.
(DMDemo is an app I made for playing scripted DMusic content:

Audigy's pretty cheap and will give you low enough latency ( < 20ms ).
You don't need a pro-audio card to do what you want to do in DMP.
Your PC should be able to handle it too unless you're using loads of
voices
and DMOs.
It's not necessarily a bad idea to run DMP on a below spec machine
anyway.
Most applications will use DM alongside other CPU / RAM heavy processes
such
as running a game so you're likely to need to keep DM content as
streamlined
as possible. The CPU meter in the bottom left of the main window in DMP
should give you an indication of how much you're pushing your machine
(not
entirely reliable though in my experience).

In the past I have usually imported midi sequences into DirectMusic=20
Producer but I would like to shift my way of working to sequence=20
directly inside of DirectMusic Producer. On my current machine which=20
is pretty old now (PIII 900 Mhz windows 2000 pro) the midi to audio=20
latency put on my machine is too high (around 400 msec) to actually=20
sequence there.
Can someone give me some recommendations about which audio card /=20
operating system / cpu I should invest in so I can sequence effectively=20
inside of DirectMusic Producer with minimal latency times?
Thanks -
