It may help you to install different devices for each format and disable
the unused formats, so that the format for each device never changes. But
I personally did not like that approach and havent tried that.
For the MADI card that would mean for example:
64 channels x 8 different formats x 9 samplerates = 4608 subdevices to
install.
Is it still true that each device that is installed will setoff a registry
access storm that will touch the registry some 15000 times per device?
Under XP, we measured an install at around 30 seconds worth of registry
access for our hardware with 32 devices. We finally changed our firmware
so it will not show 32 devices (even though our hardware can do that)
because the delay was unusable.
With the sample rate problem on Vista, having to create all these extra
"phantom" devices seems like that would make the registry access problem
much worse.
Thank you,
