I should retract my HSO sample statement.
Actually all I had to do was drag and drop the old HSO .hsb files into the Halion Browser.
Now it’s just a matter of tagging/cataloguing the sounds. As far as I can see the articulations made the jump.
The velocity mapping is a bit weird, does not run as smooth as HSO, I don’t think it would work for performing as notes cut off, legatos aren’t smooth… but the sounds (1000s of them 16 and 32 bit) are there, from here its just a matter of patience in creating the layered orchestral sets I want, and possible redesigning it into VST expression patches.
