Hi Waves,
Jst to know the difference between Sd and HD when download ultimate in the wave central, and where I can find instruments and Harmony plugin in Ableton ??.
Other thing : the HD download get stuck at 86.2 % … no way to get to 100%
HD stands for High Definition Samples whereas SD stands for standard definition.
We recommend using the HD samples as they are of higher quality and will consume less CPU when used as opposed to the SD ones.
Additionally, since those sample libraries might be a large download along with installing plugins you can download those manually from this next link
Both the plugins you mentioned should be found with a hard rescan in Ableton as per these next steps.
