Any SB Audigy 2 ZS owners out there know how to load Synth A & B ?

Mine is a OEM Version (for HP) I got used for $40, didn't know it was until I had trouble installing driver,s but that's now resolved. Mine is model SB0359 but tag says Audigy 2 ZS and SB0350, but without MIDI port and 1394 port. A real A2ZS is SB0350. 24/96 recording and playback.

Everything is working great, 2 ms latency recording on some quick testing.
BUT the Soundbank Manager doesn't seem to want to load any SF2 into Synth A or B , so I can use them in my sequencer (JAZZ++) for playback, and REAPER for recording (eventually). I don't want to be locked into the default Windows GM sounds. At least in REAPER, I can use a VST approach and connect a SF, but I only want MIDI for Drums and maybe some Pads, in spots. I do have a MIDI bassline, but that will be re-done with real bass guitar.

Maybe because I don't have a physical MIDI port on the OEM version, the program isn't functiing properly (guess)
Is there another way to load the Synths ? Manual scripts ... via INI ?
