I have got CPS running on Windows95, but under Windows2000(beta, build
2048) any attempt to start audio output hangs the GUI (the message loop
is broken), and I have to shut it down using Task Manager. Has CPS
actually been tested with Windows2000? All other NT-compatible audio
applications run without problems. Of course, for Windows2000 (and Win98
SE), audio output should aditionally support the WAVE-EX format, which
among other things supports floating-point audio streams, as well as
multi-channel speaker configurations for 5.1 surround, etc. In my
opinion, supporting this in CPS would be a major selling point.

As it happens, the Windows95 functionality will be more useful to me in
the short term, as my multi-channel card (Creamware Pulsar) only runs
under that. This leads to my next question - is it possible (a) to set
audio-out to more channels, and (b) to select the output audio device
from within CPS? I haven't found any way to do this so far. The Pulsar
can be reconfigured on the fly, and I can for example have either two
stereo devices (digital and analogue), or one 16-channel device. Other
cards, such as the Sonorus STUDI/O, Frontier WaveCenter, etc, can be
configured with 8-channel devices. My website has information on both
multi-channel cards, and WAVE_EX.

As for file i/o - import of mp4 files (as generated by SAOLC, sdif2mp4,
etc) would be very useful; and there is the full MPEG-4 file format to
look forward to later on.
