i''ve ued for a time PD in MACOS X . but now i buy a AMD 64 laptop and i have the doubt about what distro 32 or 64 bits install for audio work

what are your impressions about PD and 64 bits ?
are one of yours working with PD and 64bits ?

shit, ididn't even make the step up to 24bits....my ears are 16bit anyway i think

Hi

I have an AMD64 right now, and I don't think I can really that headaches it has caused me. Although the distros has inproven a lot for 64 bit, it's still not at a place where I would recommend you use it for audio work.
Since kernel 2.6.10 lots of things were easier to compile (I have no idea if this was just my perception or if actual improvements had been implemented). Pd 0.38 will compile in a 64 bit fc3, but not many externals will Maxlib definately wont. TAP plugins are fine but SWH plugins wont. The newest Ardour will but Muse wont. Oh, and audacity is actually compiled for 64 bit.
The hard thing is, that it is really a trial thing to find out, and you still have to know that most audio programs is written for 32 bit anyway, so you won't actually be using the extra processor power for them.
Even though I would love to be experiment with the extra computer power I took some advice from the CCRMA mailing list and just switched to 32 bit fc3 with the CCRMA kernel. You will just get more work done instead of continuingly struggling to just getting things to work and that's what it's about at the end of the day anyway.
There's some hope however. There's something called 64 studio or something to that effect. It's still in the developing stage and I believe it's a commercial product, but check it out.

Should you decide to give it a try, I would like to know if have any more luck than I did.

Good Luck.
