@ Musiclover Yes I am using Bandstand with Win 10 64bit with BIAB 64 and jBridge.
It seems that the Halion 3SE free version comes with no sound sets. You are expected to already have a version of Cubase installed which allows Halion to use the GM set that is included in Cubase.
Thank you. I vaguely remember trying to install it on windows 10 but that was 32 bit, no success, but would like to have a go now on 64 bit windows 10.
Did you have to take any additional steps to activate it, as researching this it seems that some people had to do a registry hack and add some keys to get it to work ok?
Thanks again.
