When using Arturia Analog Lab, when I buy a new synth preset pack, the sounds are not visible in Komplete Kontrol.
This is understandably a third part developer issue (they need to make sure products are indexed properly) but it tbh should not be an issue.
NI needs to work with third party developers on managing expansions installation with proper indexing in Komplete Kontrol. If there are any barriers to this issue, fix it.
