I have an S-49 Mk1 which is not compatible with the latest KK release. I'd like to get an S-49 Mk3 and use it as my main controller. At the same time I'd also like to use the Mk1 to add more controls for synths with lots of extra parameters.
If that's not possible, could I get something like Arturia's KeyLab Essential MK3, which does support the latest KK software to do the same thing?
