Anyone doing this?  I'm running the latest version of Sonar and Parallels desktop on my MacBook Pro.  I use Sonar only for editing on the laptop, but never recording.  Is this setup stable enough with low enough latency to be used as a primary recording solution?
 
Thanks

Have you tried it?

I don't have the means now.  I have an RME PCIe AES card on my desktop, but no interface for my laptop.  Hence the premise for the question. 
 
Should I bother getting an interface?  If Sonar runs like crap through Parallels, then I'll look at an alternative solution.

I don't think you will get the throughput for streaming audio at low enough latency.
Parallels has to virtualize your hardware drivers which will add an abstraction layer for the stream to have to pass through.
Then again, I may be wrong. I have not tried it.

If your going to do any recording, tracking or overdubs, then I'd pick up an interface. 
I've never managed to get much done on my laptop with one. Playback is about all that works. And even then your switching driver modes and Sonar is looking for stuff that ain't there so it's cludgy. I just take my Scarlett with me and all is good. It's pretty small. The Scarletts are super light and portable up to I guess the 6i6.

Parallels is apparently a virtualization environment with the potential problems of system overhead jatoth mentions. If your machine will run Bootcamp, then that is a different story. Bootcamp is closer to booting into Windows directly, rather than running it in a virtual machine. Some people have reported running Sonar that way. 
 
Do a regular Google search (not a forum search) using:

Yeah I've been looking at this again, windows 10 and all that. I'm looking at vmware workstation, not sure it will work but it is expensive.

In order for it to be feasible the host OS should have the smallest footprint...

Anyway is there anybody running a virtualized DAW environment? I haven't heard of a single person so far... Come forth if you are!! Does ASIO work?

I can't imagine how either of these routes would have amazing performance, but it would be cool to use my Mac for recording, especially with something portable like the Antelope Audio Zen or UA Apollo.
 
So Bootcamp will offer lower latency than the Parallels virtual environment.  Ok...I'll get to checking that out.
 
 

Not tried it as I don't have a spare copy of Windows about, but I think bootcamp should work.

Parallels lets you run Windows inside OS X.

Bootcamp simply provides the necessary drivers and dual boot interface so you can run Windows on Apple hardware and choose between OS X and Windows when you boot the computer. It's no different really to dual booting XP and Win8 using the Wondows boot manager.
