Hi,
I have just installed Halion 6 trial version, with the intention of purchasing Sonic 3 in due course. When I run Halion 6 as a standalone it works well, but not at all as a plugin within Dorico 2 pro. I get sound when mousing over the onscreen keyboard but my Kawai ES110 does not appear to be connected to the plugin. I have examined the manual, but it seems to be lacking in such basic matters. I would appreciate some help, as I have a big project in preparation …
Try going to Play mode, and select the player that is connected to the desired plug-in. I think that’s what I did to enable keyboard input. It will stay that way when you change back to Write mode.
HALion 6 does work with Dorico the same way as HALion SE or The Grand. Make sure the MIDI assignment is set up correctly and matches between Dorico and HALion; see the red circled areas in the attached picture.
