Hi Andrew and Joao, thanks for your replies. In the bin directory there are 2 different PD executables, one of which provides a msDOS command prompt which displays errors as you go. I can also test the results of changes that I make using the provided test audio and midi patch, which has built into it a way of addressing a test tone to the different dac~ outputs you mention.
Now, by using the flag -audioindev 16, I can get 8 audio inputs with the "ASIO fireface" driver setting the channel numbers to 8 in the audio options, but only provided I disable audio output. Otherwise trying to set any of the devices under output I get the error "illegal combination of I/O objects" For some reason the "ASIO fireface" driver does not appear as an option under the outputs. This seems inconsistent with a 2 channel usb one card that shows the ASIO driver as available both under inputs and outputs.

here is the listdev output....

I might have this wrong, but the audio options offer a prescribed number of chanels, you can change those to 8.

Then follow the [dac~] and [adc~] boxes with an argument for chanel number or a list

E.G. [dac~ 1 3 5] would be outputs 1, 3 and 5.

Hello List, I have trouble with an RME fireface 400 using the windows ASIO driver on a laptop. It works fine under Ableton Live on the same machine, giving me the prescribed 8 inputs and 8 outputs, but with PD i am limited to 2 in and 2 out. I have tried using the channels, audioindev and audiooutdev flags to no avail. Failing that, is there an alternative audio card anyone can recommend to give me those 8 ins and outs with pd on a windows xp or vista machine...? Nick.
