I used to use Pro Tools as a front end for Reaper! Well, in terms of hosting my instruments in Reaper and controlling them via Pro Tools. Because that's the only way I could use Pro Tools without the thing choking every 5 minutes.
Noticed that too, uh?
I like mixing in Pro Tools, and I actually like some of those AIR instruments quite a bit (the good news being that they'll soon be available as Audio Units and VST), but in terms of performance, man...
Admittedly, I'm not working w/ the most powerful machine, but, still... If I set the buffers under 64, even w/ a single track simply armed for recording and an amp sim (no matter which one), I get clicks and pops. And playback isn't even engaged!
W/ the buffers at 64, I may be able to actually record 10 or 15 seconds before PT drops out. Virtual Instruments - practically the same thing. Knowing how sensitive PT is, I even tried to accommodate it by tweaking my machine as suggested - something I never needed to do w/ Logic or Studio One.
By comparison, I very rarely need to set the buffers higher than 32 in Logic, and I often leave iTunes, Mail and Safari open in the background.
But I have zero problem running Superior Drummer + Kontakt for bass + EXS-24 (Logic's Sampler) + Amp sims + Impulse Loaders + compressions and EQs as I need them. In fact Logic never dropped out during a recording - not once. In Pro Tools, it is systematic.
