Hi there Alex,
Unfortunately, you wouldn't be able to make the most of this technology if you don't use the Rane mixers. There is a way to assign your pioneer 800 channels and EQ as MIDI controls within Serato but i am not entirely sure these controls movements would be included in the .Als file that Serato creates in "mixtape" mode...
I hope this helps
You wouldn't get Operator if you don't buy the Suite i am afraid...
