So I’ve upgraded to Dorico 3 Pro from Dorico 2 Pro and am unfortunately having problems with getting any playback sounds either through computer speakers or headphones (This issue affects both Halion and Note Performer sounds [I’ve installed the workaround that fixed the template issue with this package]). My system is Mac Mojave (latest version). I only have a basic setup (simple USB keyboard with no built in sounds). Unplugging the keyboard doesn’t remedy the playback issue. I’ve tried doing a clean reinstall of Dorico as well as a reinstall of the Halion package, but this had no effect on the problem. (I still have Dorico 2 Pro installed, which is working fine, thankfully, even using the new Halion sounds correctly).
I’ve tried changing various settings on the left-hand side of the Play window, but no joy with this either. The only difference I can discern between the loading of either playback templates using the Playback Template command on the Play menu (or on the dropdown menu on the right) is that the windows for either Note Performer or Halion do not appear automatically (these can be viewed, but you have to select the Edit Instrument button under VST instruments on the right-hand side of the page). The appearance of the edit instrument window for both Halion and Note Performer show the correct instrument, but in the case of the Halion window the keyboard at the bottom doesn’t produce any sounds. Also when playback is initiated the computer rapidly heats up, which I would think definitely suggests the system is struggling to overcome some sort of glitch.
Any assistance with this would be greatly appreciated.
