It’ll be very interesting to see how Dorico’s developers automate portamento/continuous/slide glissando playback.
I’m currently implementing it by hand (it’s not too difficult, thanks to Dorico’s excellent MIDI controller design in the Play tab), but it would be sweet to have it “just work” like so much already does in the application. It requires set-up of one’s VSTs, though, and I’m not sure that Dorico itself could do that for every VST. For the Play plug-in (EWQLSO), it’s pretty much on by default (some users might want to tweak the pitch bend range), but for Kontakt (Spitfire), I have to enable it by modifying the scripting on the relevant samples – tricky stuff.
