When selecting different products on Komplete Kontrol with the new MK3 keyboard a lot of products do not have a sound preview for example SCARBEE RICKENBACKER BASS that is included when you scroll over the presets there is no sound preview.
Because you have to install the previews, they are in a separate Previews library in Native Access
Did you do a Library rescan after updating to 3.XX? If not, that might help.
So I installed the previews library from Native Access now I am able to hear the previews but the NI Ukulele stoped working, any clue/help ?
Stopped working in what way? Installing previews should have no impact on functioning, it must be something else.
Stopped working in regards of no longer showing the preset sounds when I scroll through the instrument, all the rest are showing the sound preview.
The Uke is a recent library so the previews probably came in the installer rather than the previews library which predates it, so maybe try a reinstall?
