[RWP] useing asio driver with reaper

Wed Oct 31 18:25:03 EDT 2012

That $10 USB audio interface, with its own internal driver, wasn't 
destroyed by being overheated too hot to even touch; by the old 
computer, during itss final melt down.
It provides speech without RealTech drivers, or using Windows USB driver..
It's only problem is it is way too loud, so I have to crank the Windows 
volume control way down.
I did a test comparing latency with speech coming from that interface; 
being sure that the RealTech drivers were disabled in control Panel, 
System,  to speech with RealTech going, and overall there wasn't much 
difference, but extreme swings were reduced somewhat without RealTech 
going, so I have no doubt that it affects any system to some extent.

I might try it for speech, but so far run at 3ms with the eMu card in 
Reaper on the I7 machine, adequate for most plugs.
It's an academic issue, so far, since I don't run huge projects with 
dozens of plugs at once, but if I get something like Omnisphere, and 
it's sluggish, I'll deal with latency then.
David Shortland is successfully running Omnisphere in Reaper, with 
System Access, with the eMu 1820M, the bigger brother to my 11616M.

As to motherboards eventually having no serial ports; from 
Directron.com, I notice all kinds of adapters for serial to whatever, or 
whatever to serial.
I'd be surprised if there isn't a PCIE to serial.
I would guess that you wouldn't want a USB version 2 to serial, since 
you want to avoid a USB driver.
PCI ports are gone now, but there is a P C I E to PCI adaptor, only for 
half height PCI cards, though; or I would have already bought it.
If I could see the picture in the catalog, I maybe could tell if I could 
somehow make the adaptor bracket work on a full height PCI card.
Getting sighted help squinting at a half inch wide picture of a strange 
computer device is an exercise in frustration.
I think, with an adapter between a full height sound card and the PCIE 
slot, there's no way the sound card's jacks are going to appear at the 
usual opening at the back of the computer.
There is another PCIE to PCI adapter that has a cable and runs the PCI 
card outside the computer, but it has 4 PCI slots and costs many hundreds.
  If the simpler $36 PCIE to PCI adaptor could work, though, I'd gladly 
use my old eMu PCI card for speech.
