this might be an obvious observation though, have you verified that the standalone (samplv1_jack) does not auto-connect its jack audio outputs? you'll have to make a patchbay rule for just that or connect them manually, of course, same for midi input.
to start a new patch from scratch (blank) you just need to hit the "New preset", first button on the top-left (depicted by a white blank sheet); then you certainly need to load a new audio sample file by double-clicking on the wide canvas rectangle just below.
i believe that you know all this and more by now. i am just checking out the obvious ;)
