sorry to here that.
yes and no.
i can load/reaktor presets and save/load my projects with no bugs, but this was only true for the included factory presets. my own stuff and the ensembles you can find in Reaktor 6 Factory Content (Fullversion) or Reaktor User Library were load- but not save-able, btw you could save them but they stoped working after you would reload your project or even when using the undo function.
But when i tried the ensembles i made with Reaktor 5 this problem is not present. All of Reaktor 5 Factory ensembles are working with no issues. weird.
i also had some minor problems with my machine +. no connection, crashes (2x) during the installation of content packages, changing the audio connection or midi, when starting the controller mode, remove the sd card… But the firmware update went smoothly and after i changed the sd card and did a hard reset (in setting menu)
it seems to me that everything works a little better.
