Traktor s4 mk1 / Traktor pro 3

hi all, quick question for you all....

i have a mk1 s4 and just purchased a newer macpro than what i had and is running Catalina osx. i managed to get the mk1 driver working and all is good, well as far as being able to use my mk1 s4. The problem i have is there is no sound control in the main onboard mixer and this wont let me record within tracktor. i have tried down other routes as wanted to start to steam so installed sound flower and OBS. I created the aggregate fine and in the sound options in settings this recognises a sound car with controls but sill no recording. i can change the input device in the traktor settings to onboard and this records but no controller. i have even tried sound forge and Audacity but with me having no volume control in the settings for traktor these are useless.

question is has anyone came across this and fixed the issue or do i have to dig in the pockets and purchase a new mk3 controler. If the later is the answer then is the S2 mk3 as good as the reviews?
