Where Are Coremidi Patchlists For Synths In Dp4?, Exp'd DP3 user can't see patches in DP4 Options

[BobbyA]

To anyone familiar with Core MIDI or Digital Performer 4 with OSX:
Where are the OSX CoreMIDI patchlists for synthesizers?
I use MOTU's Digital Performer and just recently upgraded to DP4. Well, now they say I don't need to use OMS or FreeMIDI anymore (that's where the patchlists for all musical MIDI gear were kept). They say that the new CoreMIDI doesn't need OMS or FreeMIDI, so now I ask where are the synth patch lists in OSX?
In DP, I used to be able to click on the Patch or Default Patch column next to the MIDI track I was recording onto, for example, my Kurzweil K2500. Upon clicking there, a big list of sound patches (ie Piano, E Bass, Strings, etc.) would pop up showing me all the hundreds of synth programs on my Kurzweil.
Now, with OSX and DP4, I click there and ... no patches pop up. I've tried everything to find the patch lists to no avail.
I tried checking all the DP4 preferences, MIDI assignments, etc., but I can see nothing.
I figured that maybe the patchlists are now stored in the Audio & MIDI Setup page of OSX. But there's nothing there that refers to MIDI patches or instruments. I thought that clicking on "Scan MIDI" would have it locate all my hardware synths via MIDI, but it doesn't seem to find my MIDI gear. This has got me major baffled!

Is there anyone out there who can shed some light on my problem?
[I'm using a Dual 500Mhz PowerPC G4 with Mac OSX 10.2.3, 438MB RAM, a MOTU MIDI Timepiece AV MIDI interface, a MOTU 828 audio interface, and MOTU's Digital Performer 4.]

Thanks!
