Can Ardour record 4 tracks from two different 2-channel devices on os-x?
I have a firewire 2ch box and need 4ch’s for a current project, can ardour use the two channels from the built in intelHD-chip and do
simultanoius 4-track recording?
You can build an “aggregate device” using Applications->Utilities->Audio MIDI Setup. Then tell JACK to use that device.
For linux heads, this is equivalent, roughly, to setting up an ALSA “multi” device, except that there is a nice little GUI for it.
Note that you must be a user with administrative priviledge for this to work, even though there will no errors or warnings if you are not.
BTW, even though this is possible, its a bad idea. I’m not going to explain why here - there are lots of references to this if you google for the idea.
