I've been into pro audio for 20 years. Mainly as a live sound engineer but also running a small mobile studio to record bands and/or shows on location. I've been stuck to Mac since the day one all along the PowerMac years, but as you know, the enforced Intel switch slowly moved Apple away from the pro target and keeps going in that direction. So I switched from ProTools and Mac to Samplitude and Windows. Later jumped to Reaper.
Never liked Windows. It drives me crazy, but what else.... Mac OS X is not what it used to be. I'm stuck in Snow Leopard and never got any Macintel gear since my beloved PowerMac G5 went obsolete. I used Dual boot Hackintoshes along with a Win OS (for audio exclusively) eversince. Now my current workstation has died and I think it's the right time for a major change. I don't think I will keep using Mac OS X. I just installed Kubuntu in a borrowed modest PC to keep running until I manage to afford a new machine. I don't expect to get rid of Windows anytime soon, but I want to explore my chances in Linux audio. I currently have a Fireface 800, thankfully supported on Linux! And a RME HDSP is on my wish list. I normally track on an Alesis HD-24XR so an HDSP is a kind of must-have tool. - thankfully the great HD24tools by Marc R.J. Brevoort has a Linux version I still have to try. This borrowed PC doesn't have a firewire ports yet -
These are first steps. I'm a totally noob with ALSA and Jack. I just installed Reaper and worked for a while, but I screwed it up in just two days. Please be patient with me. I have a zillion newbie questions in my bag!
