On a G5? At what processor load % can you still use a buffer of 64? I ask because I'm looking for a solution that will enable me to use an I/O buffer of 128 with a reasonable (say 50%) processor load. The RME 9652 is one of the cards that might be useful for this. Best, Zip

What interfaces are you using? On a G5? At what processor load % can you still use a buffer of 64? Interfaces, what do you mean. I use an old PCI Hammerfall 9652 with Swissonic 24 bit converters and it runs through a 2.3 PCI-X G5. None of it is still available but that's only because of the public demand for new products. Both are working very well, Swissonic has been taken over, RME has an updated version of 9652 which I believe does more or less the same thing as the old one and the G5 PCI-X line has been updated with the quad series. It's very difficults to be exact about the processor load because I also have a Powercore Mrk II and a UAD1 which puts extra strain on the machine and I guess without them it would run faster. Anyway I like it as it is and basically I have 2 Space Designers, 1 Classicverb (Powercore), 1 Tape Delay, 1 Ohmboyz delay, 1 Logic Phaser, 1 Logic Chorus and 1 Logic Flanger in my autoload. If I stay with that I can record at least 16 tracks at the time with the 64 buffersetting. I can also use Equim EQs en mas without any problems. As soon as I start to add virtual instruments it's game over and I have to go to the 128 setting which pretty much can carry me through most projects. I have a recent project that has 72 audiotracks and 14 EXS's, 1 ES2 and a EVP88 and it still works at 128. I do hase 4.5 GBs of ram which isn't unimportant in this case.

The > RME 9652 is one of the cards that might be useful for this. I'm on a G5 Dual 2.0GHZ with RME Multiface and 128 sample buffer is possible with very high CPU loads. Generally speaking your best bet would be a PCI audio solution as they are generally lower latency and lower CPU load than most other brands. Drivers have a huge influence on this. Make sure you pick an interface that has it's own drivers rather than simply uses OSX's built in one to get best performance. RME & MOTU for PCI and the same plus Metric Halo for Firewire based interfaces will generally be your safest bet. ::::::::::::::::::::::::::::::::::::::::::::::::::: Paul Najar Jaminajar Music Production www.jaminajar.com
