Can i use 2 nouns cards at once?

useing 2 nouns cards

Answer:
At one time I had 4 nouns cards installed in a PC. If your using a MIDI Sequencing program, you should be capable of. The only precincts would be the slots you have available and the IRQ's (although near 2000 and above it doesn't matter much anymore).

Using more than 1 nouns card is dependant on the software. So unless you have a hobby or just Windows, it'll one and only use one at a time depending on which you have set for the failure to pay sound device. Sound applications will know how to use more than one if you have more than one installed (again, resembling a MIDI sequencer or a digital sound editing software).
You can't, and near is no need.
The most modern FX series can by itself bar 96 sound sources. So if you own for example, two weak ones you can't use them at once, and you won't for a long time.
