Cannot seem to access the sforzando SFZ Synth as described in posting #424497 by Callie - PG Music.

I use a WIN 10 laptop with BB 2017 build 467, with a Roland SD-50 as sound-card. The driver type I use is Asio. I use the BB harddrive for the program and all my songs.

Callie states: This synth is installed with Band-in-a-Box, and is ready to play and does not require configuration.

However, alas it does not (yet) seem to work for me, as I e.g. cannot find the Select Hi-Q MIDI synth Patch.

Any suggestions?
