Noel,
Following the procedure on the laptop, I see that I don't have ST installed as a VST synth, only as a DXI. So I proceeded with it s DXI.
All piano instruments played successfully. But:
a) I still can't find the HQ files when clicking on "Select Hi-Q Midi Synth Patch....". (Is this a problem?)
b) In the very last step, I had to click on "Default Synth" instead of "Piano" to verify that ST is working. (Is this a problem?
Should re-install ST as a VST?
Thanks!
