[PD] asio problem in test 28

[Miller Puckette]

Hi Dave,

I'm stumped over this one.  It's conceivable that the ASIO driver wouldn't
support two channel I/O (maybe you have to open more channels?) or perhaps
the driver won't handle input and output simultaneously (so try "-noadc"
and "-nodac" to see if either helps...)

cheers
Miller

The device is similar to the new Digidesign MBox with a few more features.  The device works great in PD with standard drivers - except the latency is annoying.  And (as far as I can tell) it works in Cool Edit Pro with the ASIO drivers, but PD causes the following problems when I use the -asio flag:
