Hi Andi
Please find attached a screen shot of the Violins 1 Expression Map after a fresh load of generated playback template. As you can see it shows CC2 as secondary control and not CC1 as it should be. For Percussion it is correct it shows CC1 and also loads VelXF rolls Mod (as used in the EM)
Also attached one loaded instrument after the fresh load of the template. As you see CC2 is not activated. This is the case for all instruments woodwinds (CC2), brass (CC2( and percussion (CC1).
Just my opinion but if you have more than 30 instruments the pre-balancing of all instruments is a main time saver. If you have to adapt 30+ instruments each time you start a project the whole point of a template would be lost. Worse in Dorico it sets back CC7 each time you start playback. This is why I assigned CC3 to CC7 in all my templates. The only other option is to write automation for CC7 from the first note in your template which is rather uncommon. I normally only use CC7 to balance between instruments like you do in the SY player but also between different library providers.
