I'm running into a problem that I'm hoping someone has a solution to - it has to do with importing midi from an external source (in my case, Sibelius) into my DAW (logic pro) and for some reason both spitfire solo strings and BBC orch pro have the issue demonstrated in the attached video. It seems to drop notes entirely or play notes with a super quiet attack, and no matter how I adjust the midi it doesn't help. For example, overlapping or separating them doesn't change it, and even if both notes have the same velocity it's the same thing. If I play the music into the DAW from my keyboard, it's fine, this is only on imported MIDI.  Every other sample library plays normally, so it does seem to be Spitfire-specific. I'm hoping it's a classic case of toggle some hidden setting somewhere, but any light you could shed on this would be enormously appreciated!
