[RWP] ASIO Settings

[Indigo]

Hi Scott,
Isn't the default Reaper buffer size something enormous, like 1040 samples?
My daw is off line, and the Reaper 64 on this online computer is showing 
a buffer for the RealTech onboard sound chip.
If I reduce it below about 380 samples with Realtech, I definitely get 
crackling if I play a fat soft synth, so the Reaper buffer definitely 
seems to work to affect crackling; at least for the onboard sound chip.
I've never taken RealTech seriously for anything except speech, and now, 
after a shorted headphone jack caused RealTech to throw a huge hissy 
fit,  I've ordered Asus Xoner PCI express X1 soundcards for speech in 
both computers, and will finally shut down RealTech.
I've been hearing for years that RealTech is bad to use, even for 
speech, that it affects music recording done on  good interfaces.
It'll be interesting to shut down RealTech, delete its drivers, get 
speech from decent PCIE cards, and learn how much effect running without 
RealTech  has on recording.
Should free up a tiny bit of ram at the very least, and divert the 
number of calls onto another piece of hardware.
