After emailing AudioEase, apparently Altiverb is a VST2. Also, a VST3 version of Altiverb is unlikely to be forthcoming. In my Mac plugins folder Altiverb is installed in the VST folder and not in a folder called VST2 which is actually empty. Apparently VST2’s use the .vst file extension so they just get installed in the VST folder…This was my original confusion. I have tried to do the HelpCenter procedure for using vst2’s but it doesn’t seem to work, unless I am dong something wrong. Unfortunately I do not understand how to implement Shiki’s suggestion from above. I have done a diagnostic report as you suggested and will email it to you incase that helps!
Is anyone successfully using Altiverb with Dorico?
Why does Dorico not accept VST2’s as standard like Cubase and Nuendo?
