Sorry if this has been covered already, but I couldn't find it on a quick search...

here's the background: I have an iMac dual g4 and currently run Reason 2.0 with a Tascam US-428 in osX. I've been trying to hold out for something affordable, or at least stable in osX (am considering Deck 3.5 as my cheap option or Cubase SX as my complete option) but would really like to get down to recording some audio after having this equipment for 4 months. So, I'm going to quit being stubborn and see what I can do with the OEM versions of Cubasis VST and Deck LE that come bundled with the US-428 - and nobody needs to remind me how limited these programs are - I just want to finally track a bass line!

here's the question(s): Obviously I'll need to install these programs in os9. First off, will I need to install the os9 US-428 drivers and/or reinstall Reason in os9? Secondly, will the existing osX files (US-428 driver and Reason) cause any kind of problems? Anything else I should keep in mind, or am I making this more difficult than it seems? Thanks in advance...

Installed Jaguar a few weeks ago onto my existing OS9 G4.

My OS9 sits on a different partition. Your OS9 should reside in it's own folder.

To boot in OS9, go to the Apple menu/system preferences/ startup disk. choose OS9 and restart.

You should now be in OS9 and you can load your drivers and play with your toys.

To return to OSX under the Apple menu/ control panels/ startup disk choose OS10.2 and restart.

I do it all the time, the OS9 drivers will not interfere with OSX, they are installed to different locations

Thanks g-dub. I've been to os9 land before - just don't like it (not as pretty) My main concern was any conflicts, which there don't seem to be.

As I'm writing this, another question has popped into my head - in the long run, after osX apps are stable enough to leave os9 behind for good, I'm guessing that having this separate partition won't be the most efficient use of the disk. Is there an easy way to reconfigure the system? It can't be as easy as just trashing the os9 folder, can it?

Yes it is that easy. But i still need 9 for most of my apps.

There is no chance for conflicts, components and drivers are loaded in different places, and OS9 can't do anything with an OS10 component.
