For anyone interested in a dimension limit workaround for GigaStudio 2.5 and Horizon Opus 1 and Horizon Solo Strings please check out the following link on the VSL Gigastudio Forum:

Dimension Limit Workaround Discussion

With this workaround, you can now create a stereo legato performance instrument with up to 4 (that’s right 4) velocity layers. This instrument can be played in real time on just one midi channel and works flawlessly with the Horizon legato performance tool.

You can also create a stereo “expanded basic all” instrument with up to 16 keyswitch patches and each patch can have up to 4 (there’s that number 4 again) velocity layers.

There are also several free .art and .gsp files for you enjoy.
