Both of these require a Steinberg USB dongle. The stand alone version can handle up to 64 channels (over 4 input ports). Sonic and Halion 5 come with stand alone, VST2 and VST3 plugin options. At this time Sonic and H5 both require a Steinberg USB dongle. In these players, HSO gets a special macro screen that looks very similar to the screen shot offered above, but you can load up several of them at once in the same instance if you like. HSO also works as a content library in Halion 4/5/etc. If you do not use the dongle option, it can be a bit fussy to move around from machine to machine (requires interaction with your MySteinberg account).Ĭlick for image of the included HSO VST2 UI. As far as I know, you can only use HSO on one computer at a time (either in soft-eLicenser or on a dongle). HSO does not require a Steinberg USB dongle, but it can be moved to one permenantly if you so choose. The included VSTi is a single instrument/patch per instance UI. It comes with a small VST2 interface in one of the Extras folders that is VST2 compatible with Sibelius. I have Halion Symphonic Orchestra (HSO) as it is currently sold on its own as a sound library.
