I'm running Altiverb 4 in Logic 7.1 w/ G5 dual 2.7 and Tiger. I like to work with a buffer setting of 256, but if I have more than 2 Altiverb instances, I get a lot of pops and crackles. Is this normal?
Will I get more instances of Altiverb if I upgrade to version 5.
There's a huge improvement in Altiverb from 4 to 5 as far as efficiency. I'm also not sure about Tiger, but on Panther on a Dual 2.0 I can run at least 5 without having any problems and on v4 2 would bring it to its knees. It's really an essential upgrade, with all the new EQ and placement stuff.
