[RWP] Any USB audio device into Reaper

Thanks, Patrick,
I'm updating this vocal pedal this morning to the latest firmware, which 
may solve some issues.
Others on the Helicon forums are running USB into both PC's and Macs 
without latency, so I must be missing something.
I also found some using Reaper, so Reaper itself can't be entirely to blame.
I listened to the half hour long Helicon video on hooking the pedal by 
USB;using the aggregate audio devices; into Logic; and it was a huge 
hassle, requiring no less than 10 reboots of the computer, so it's not 
simple on Mac either.
asio4All is said to introduce around 10 to 20ms of its own latency, 
which doesn't seem such a great solution.

I finally found a line in the answers from Helicon; saying that asio is 
required to control the generic Microsoft audio USB driver, so the USB 
pedal is indeed competing with the soundcard for use of asio.
That's the obvious explanation for why they both aren't shown 
simultaneously on Reaper's audio device list.

I won't give up, I'll find some method.
After fully updating firmware in the pedal, I'll try ReaInsert, said to 
run any hardware as a virtual plug.
I don't know yet how ReaInsert works; maybe isolate the pedal so it can 
have its own asio driver, I hope for that miracle.
Otherwise, I'll record vocal lines from this pedal in Sonar X1, which is 
said to have a special mode to recognize and handle audio USB devices, 
like USB microphones.
This pedal should be exactly like running a USB microphone, or any USB 
audio interface.
If I didn't have the eMu 1616M P C I E soundcard installed, with its 
propriatary asio driver, n Reaper's preferences/audio/driver maybe I 
could use a generic asio driver that would run the pedal without latency.
But then I wouldn't have the eMu preAmp to plug my ribbon microphone 
into, which is what I want.
If all else fails, I'll rewire 1 daw to another, the first daw with the 
preAmp on asio, the second daw  with the pedal on its own asio.

Mac core audio has a nice thing called aggregate audio devices, which allows you to use individual interfaces  as one multi-channel device, which doesn't seem to effect latency. The closest I've seen to this in Windows is asio4all, which has it's own set of issues.
