I’m beginning the long journey of writing out an expression map for Spitfire Audio BBCSO. Was having trouble getting keyswitches to work for a while, until I finally realized that BBCSO has many of their keyswitches set to negative values. In other words, legato is set to C-1, which is not a hyphen, it means one octave below C0. When I enter “F#-1” Dorico actually interprets that as “F#0”.
If I could get Dorico to recognize these values, it’d make things a little simpler because I could have a lot more instruments using a single expression map, rather than, say, using low note triggers for high strings and high note triggers for low strings. Having universal triggers would be simpler.
Not a huge deal, since I’m bumping up against the lack of universal standards and 3rd party software, but I still thought I’d ask.
Edit: I think I figured it out but I’ll leave this up in case it’s helpful to others. It just came down to the “middle C” issue. BBCSO and Dorico’s default are different by one octave. Mystery solved.
