I have certain equipment and need some help in wiring it together.
imac dvse 400mhz
a small analogue mixer (11 channels in total)
home stereo separates amplifier
akai S3000XL midi digital sampler
USB Midiman Midisport 2x2 midi interface.
cheap keyboard with midi output only.
MIDI Out of your keyboard to MIDI in on your MidiSport interface.
Midi Out of your MidiSport interface to MIDI In on your Akai sampler. That's all you really need for MIDI cables for now.
Plug the MIDI interface into a USB port on your iMac, preferable not on the keyboard.
Plug the 'Control Room' or 'Monitor' stereo outputs of your mixing desk into a line-level input on your hi-fi amp (CD, Tuner, Aux will do fine)
For now, plug the Main stereo L/R outputs of your Akai sampler into two channels (or one stereo channel) of your mixer.
Get yourself a couple of leads with a stereo mini-jack on one end and 2 phono sockets on the other end. You can get these leads from Tandy (Radio Shack.) for now, plug the spkr output (on the side of your iMac) to another couple of channels on your mixer.
This set up, once you've installed any necessary drivers for the MIDI interface, will allow you to record and play MIDI, and hear your Akai (and any internal iMac sounds/plug-ins) through your hi-fi amp, via your mixer.
As for recording acoustic sound sources onto your iMac - if this is something you want to do - you'll have to examine your particular mixer for the most suitable way for your particular requirements. I assume your mixer is a basic stereo out, so not ideally suited to multitrack recording/monitoring, and would personally be tempted to use one or two pre-fade auxilliaries you feed the iMac's input.
As far as running Mac OS X on your iMac, I think you'll get better mileage sticking with 9. The iMac is below minimum requirements for Cubase SX, and OS X itself has more of an overhead, especially where multimedia applications are concerned.
