Thanks Fiddler, switching channel did not work.
Per suggestion from PG tech.... I re-installed H.Sonic. Did not do it. It crashes when volumes on HS are moved. Strange thing is... I have tried a midi file that had volume program changes, sliders were moving like a brand new train on oiled tracks-no crashes. Happens when I manually move them. With several other indications, I am 90% sure it is BIAB bug. It works solid in DAW and other places as VST.
