Only one channel appearing in Mixer for 16-output Kontakt

Having a problem in 16 output Kontakt 7 and Dorico Elements 5.1 where only one channel of the multi shows up in the Mixer

instruments disappear when exp maps from the web are applied

Check the Endpoint Setup dialog for your Kontakt instance to make sure it’s not set to show only one output for some reason. If that doesn’t help, double-check that you really have instantiated the multi-output version of Kontakt.
