Iain (and others),
The basic example is below (I tried to make it close to
the one in the manual - including using the "beats.wav" from the distro). Of
course, the MIDI device number will likely need changing for a given
system.
Controller 7 is the volume control on most MIDI
keyboards.
I've tested this with several controllers and on both
Csound 5.06 and 5.10 - with results as previously described.
The file is looped (final "1" in diskin line) so you have
time to experiment with controller 7's settings. Without the ctrlinit command,
even with CC7 set to zero, "beats.wav" starts out full blast. With ctrlinit, the
result is as expected.
I'd appreciate feedback. And if my observations are
verified, I'd be happy, for a developer to take a look at the diskin
code.

HI Art,
Could you
post the full example? I tried what you have posted here and don't get the
same results you seem to be getting. Admittedly I'm using the virtual midi
device, I have no hardware handy at the moment.
