I have a Presonus FP10 FireWire audio interface. The manual states that it has "26 simultaneous inputs and outputs". I take that to mean I can connect 26 mono instruments/mics to it. Currently, I have a Radias connected to inputs 3 and 4, a Kronos connected to inputs 5 and 6, a Motif Rack ES connected to inputs 7 and 8, a PS60 connected to Line Inputs 1 and 2 on the rear of the FP10 (thus disallowing any connections to inputs 1 and 2 on the front of the FP10), and, finally, an M3 connected via Toslink to the SPDIF input on the rear of the FP10. That gives me a total of 5 stereo input devices to the FP10.
If I chose to input mono audio instead of stereo pairs, I would still have only 9 devices input to the FP10.
So how can Presonus, or any manufacturer of this kind of interface make claims of 26 inputs? I must be missing something because other interfaces look just like the FP10 but claim 18 or more inputs.
I wanted to buy another audio interface to use to connect 2 more stereo devices to my system, but Ableton claims Live 8 can handle only one interface. Getting another FP10 to run in series with my current one seems impractical due to differences in firmware, etc, so I don't want to do that.
I have read that the OS X Audio/MIDI utility can create an aggregate device out of multiple hardware devices but I don't know if that would work because I have no other interface (yet) to test that.
So...what am I missing?
How can I get 7, much less 26, inputs into Live 8, either with the hardware I have now or with another interface?
Thanks for any help you can provide.
