Motu 324pci Vs. 424pci Vs. Firwire., stutering and latency Options

[hani]

im currently using :

mac g4 1.3 ghz osx 10.3.9
motu pci 324 w/ 1224 IO.
cubase 2.2sx.

i have set my buffer very high (1024 samples). and still getting stutering .
and cant play any vstI synths in real time due to very bad latency .

i cant set the buffer any lower because the stutering will increase .

should i switch to Motu pci 424 or firewire? or switch brands .. will the latency & stutering issues improve?

any cubase users out ther? what do you reccomend? what are you using?
i dont need much!! just the basic 8 out/in digital I/O and if midi is included that would be cool too.

please help.

i'm quite sure your motu interface is not the bottleneck within this system.

Some other ideas for improving your system:

- Try recording with 44.1kHz
- Try recording in 16 bit (i know is not really an option, but will decrease the amount of data transferred over the pci bus)
- Check your harddisk drive.
The faster the disk, the more files you can playback at the same time without stuttering.
Separating audio files and the operating system to two independend disks will increase throughput.
If you have 2 disks installed make sure they are located on different host controllers.
