I haven't used my Kurzweil K2500 in nearly a decade, and the last time I had it hooked up to my computer, it was connected via an M-Audio firewire midi/audio interface to a Mac G4 and I was using Logic 5. Now I'm interested in making music again, and I'm wondering what my best MIDI + AUDIO interface option is for connecting it to my current Mac Pro. The K2500 will be the only hardware synth/sampler I need to connect, and I only need an interface that is capable enough to use all available MIDI channels and ideally simultaneously record the audio coming back from the keyboard, on multiple channels. Thanks, Adam
