after installing new soundset ,Should we keep the old HSO content…???the new HSO comes in one dvd …old was on two…that means less samples…?

If you want to use HSO as a plugin in another host, or as a standalone, I’d imagine it would make sense to leave it installed.

The HALion Symphonic Orchestra - VST Sound Instrument Set, which is provided with Cubase 6 is an add on for HALion Sonic / HALion Sonic SE. The new content is not compatible with the old plugin / standalone version of HALion Symphonic Orchestra. If you want to use the old plugin / standalone, you have to keep the old content installed.
