Ok I've found now that the new version totalmixfx_102b6_win is working fine with 4 korg NanoKontrols,
It seems you overlooked (or did not understand) Ralf's comment in the other thread:
But, as I remember, in older versions basic initialisation of Channel Layout did not enable remotes 3 and 4 by default. When you have settings files first generated from older Totalmix versions, you would have to enable MIDI Remote 3/4 manually in Channel Layout Dialog.
Not Settings/Midi (Midi in use) - but Channel Layout dialog! For all three tabs Input, Playback and Output one has to manually activate remotes 3 and 4. There has been no changes with MIDI remote in all the last versions, so it is quite unlikely that one version works and another one does not.
