I just loaded up SubLab XL in Acid Pro 11 and can also can’t get SubLab XL to respond to midi notes.
I’m not a Acid Pro user and its my first time loading it since maybe 2003.
Have you been able to get an Arturia plug-ins to work in Acid?
The interface is loading and the presets also change and the animations work ( albeit some glitches with the blob ). This means that the audio engine is working fine, the problem is related to midi, in that the midi notes are not getting to SubLab XL, that is why it won’t sound.
I’ve done a bit of digging around and on the magix forum, there are other having what looks like a similar issue. With Vital, it seems that Acid Pro loads the VST3, which due to a bug in Acid, it won’t play midi notes. Its the same problem as SubLab XL. Have you tried loading the VST version of SubLab XL? I can’t seem to figure out how to do this and due to not being an acid user, it would be great if you can check and see if it works.
