I am getting no sound when inputting notes (although the notes appear on the screen when using my MIDI keyboard. I also get no sound when clicking playback. Further there is no sound when clicking on the keys of the HalionSE included with Dorico. I have tried clicking Load Sounds for Unassigned Instruments which had no effect.
I am using a Mac Pro (2.93 GHz Quad-Core Intel Xeon) running El Capitan through a MOTU 828mk3 with an Arturia Keylab 61 MIDI keyboard. The setup works brilliantly through Sibelius 8 and also through Logic Pro and Cubase.
I tried attached the VSTAudio Engine files but your website said the upload was too large.
Thanks for your help.
