Hanno, Thanks for your reply. My idea for getting the G3 upgrade is so that i can make use of the Mac's AV capabilities for more tracks. I have the capability of recording through either my AMII or CBX D5 , but I want to use these alongside the xxx number of tracks I can get on the AV side, or have them transferred and played back through the Mac for realtime effects, compression, further mixdown ,etc. I don't want to upgrade just because of screen redraws and processing times, etc - I want many tracks and plug-ins - that is, until I upgrade my jaz disk too! (I cannot find the original Beige G3's anywhere in Hong Kong and i don't want to upgrade to new G3/4 and worry about USB interfaces and SCSI adapters and the like.) So, when you say the card does not record in stereo, you mean i cannot record(split stereo) using AMII within Logic? Or do you just mean I cannot record stereo interleaved files in Logic using AMII (didn't know i could do that anyways) or did you mean you just cannot record with AMII when using SD II? So if the card does not support ASIO, can I still use Mac AV (as opposed to ASIO with Sound Manager driver) option with the Sonnet card then? in other words, lots of audio tracks and real time plug-ins...tha's what I'm craving How many tracks are you getting out of your Sonnet card? Thanks to all replies and sorry for long email Ken Hanno wrote: you can not record stereo with the sonnet with SD II and AM 2 . to do that you must restart without the sonnet extension. also: no direct I/O with nubus no ASIO with nubus
