Pro-audio, 32-bit or 64-bit?

I have a 64-bit system (two AMD Opterons). I was wondering if I should rebuild Gentoo using 32-bits for pro-audio purposes. Some programs seem to have trouble with 64-bits (such as Ardour with VST).

Lately, the problem I've been having is that Ardour constantly quits, usually right after loading. This actually started happening after I ran emerge -e world. No idea why. But today I'm wondering if I should really run this system in 32-bit mode.

Well well well... I am discovering this either... :evil:

I was buildind my gentoo dead sure everything was operational in 64 bits and expecting multilib to deal with the rest !

Well... it does seem that mulitlib allows running 32 bits executable in a 64 bit environment.
But... it does seem that running a 32 bits plugin in a 64 bits host is a totally different story.

And as long as you are using 32 bits VST plugins... I fear that... if there is a solution keeping the 64 bits environment, it is not going to be an aesthetic one.
I do would like to understand things differently but I fear that the only solution for keeping a 64 bits system while wishing to use 32 bits VST plugins will imply to build a 32 bits host in a 32 bits chrooted environment ! :cry:

If someone can contradict, I will be more than pleased !

Yeah, that's about what I understand too. Ardour in particular won't compile with VST support on 64-bit systems.

64-bit systems have been around for a while. What's the holdup? :evil:

Well well... from what I read from Ardour together with what I can see by myself... Even 32 bits Ardour (2.7) does not seem very happy with VST plugins...
Which would mean that the choice you get is keeping 64 and having building problems or going back 32 and... experiencing runtime troubles ! :mrgreen:

A double-sided holdup... ! :wink:

My decision is that if I do need VST plugins, I will stay under the OS they are made for... :roll:

I do not see Wine as a solution. (by itself or via VST plugins converters) I failed making my Cakewalk Pro-Audio 8 work reliably under wine. I even cannot imagine any Wine based solution not necessarily leading to unsolvable synchronization problems.
Most likely, I will forget all about VST plugins...
