The Output units will flatten all of the devices streams into a single stream. You set the format of data that you want to give the output unit (ie. the format of its input), and it will then give you those channels (starting from channel 1 on the device) to you.

Now, if you want to say get channels 1,2,10,11 from the device for a 4 channel stream, then you set the channel map property on the output unit to get those channels - this is true in either input from a device or output to a device. It was covered in a recent email I wrote (a week or so ago)

The output unit will turn off the streams of the device that you aren't using as well for efficiency.

Hi,

can I access multiple streams of one device simultaneously over the HALOutputUnit? I wrote an application that's using such a unit for output, and now I'd like to use 10 channels on a MOTU 828. The MOTU has 14 outputs split in 4 streams with 2, 8, 2 and 2 channels, can I access all these from one output AU?

Thanks,
Stefan
