With Halion SE in Dorico: If there is some reason you need to ‘extend’ the range of an instrument it is possible to stack Presets (Such as HSO Clarinet with GM Clarinet), set them to the same channel, and use the MIDI Tab in Halion SE to split the keyboard among the patches.
While it’s not as thorough as Halion 5, where one can actually edit the HSO sample zones, filters, etc. of a preset, it might be useful for such occasions where you just need to extend the range of an instrument a bit, but still keep the bulk of the instrument’s range using HSO.
Here is a thread discussing the technique.
