Not that this comes as any surprise but I thought I would mention this.
Loaded Absynth 6.01 into KK v2.9.6 and was pleasantly surprised to see the instrument load up and have KK operate normally while scrolling presets etc.
I can hear cool previews for ANY preset - including ALL the prior libraries listed under the Banks menu (third knob from left on the S61) but if I land on a preset within KK v2.9.6 which is NOT from the new Absynth 6 library (like say something from Absynth 5 or Absynth Legacy etc) and click Load (8th button in the upper right) - while the selected preset name does "appear" correctly with the KK v2.9.6 interface - the preset itself - does not load into Absynth 6.
Conversely - any preset from the new AS6 library - loads normally.
Maybe I am missing a scan option or something else - and I realize that KK v2.9.6 is not supported - but just putting this out there for anyone else who still uses KK v2.9.6 and gets tripped up by this.
If there is an easy solution - hoping someone can chime in.
