Hi,
Recently got Dorico Elements 3 as a part of the StayHome collection so I can learn Dorico as my school is changing from Sibelius to it this September. The piece I am currently writing includes arpeggios, so I have attached the symbols to the chords however in Playback they don’t play.
I was wondering if I was doing something wrong or whether arpeggio playback just isn’t a feature in Elements 3.
Thanks 
Welcome to the forum, sa_muelj. Arpeggios should play back in Elements, but if you played in your music in real time or imported MIDI files, then the played onsets will be overriding the automatic adjustments of the onsets. Try selecting the notes and doing Play > Reset Playback Overrides.
Hi, thanks for the welcome Yeah I imported my Sibelius file as a midi file (Sibelius First won’t allow an .xml file export annoyingly). Done what you said and its working perfectly! Thanks so much!
