Re: [linux-audio-user] 2x RME Multifaces, ALSA, JACK & Ardour -> XRUNS?

Hi Edwin
Give Fervent software.com a look:

http://www.ferventsoftware.com

I got a disk from them and you can run from the CD to check stuff out.
I then installed it to the HD and it's been running ever since.
I recorded the song below using it ( Ardour - jammin)

At least you may get some help from Chris
seems quick on the mails as support.

Cheers
Bob
