garritan personal orchestra / Aria player
I've just bought Logic Pro X and I'm happy to see that the software instruments are better organized and easier to find than they were with Logic Pro 8.
Having said that I am having trouble with 3rd party instruments. Although Garritan Personal Orchestra came right up with Logic Pro 8, I can't access it with the new Logic Pro. Nor can I access my Steinberg instruments as I could before.
I have tried installing Aria Player before installing Logic Pro X and also after, I'm still seeing nothing. Maybe my old instruments are incompatible, I'm not sure how to find out.
You should know that I'm running a patched version of High Sierra in order to be able to buy the current Logic (I was on El Capitan before) and that might be a factor.
Thanks for being here to help.
OS X El Capitan (10.11.6)
