Just bought the MC7000 (after ditching my Pioneer SX3 for multide of issues). So far very happy with the unit, but the platters are intermittent in working. They often default to ‘cdj’ mode where turning the platters results in very very slow turning of the platter. I read through the forum which seems to suggest adjusting the sensitivity, but this seems like a cop out reply. I am pushing down with all my strength and they still wont turn or stop the track from playing (like vinyl is supposed to). Why would I have to adjust the sensitivity if theyre set to ‘0’ by default? Clearly there;s some other issue going on, right?
My success rate with the decks is as follows: Deck 1 - 60%, Deck 3 - 85%, Deck 2 - 25%, Deck 4 - 30% So clearly the left deck is better than the right. PLus also the right deck’s ‘vinyl’ button is always off by default (which seems weird).
And yes i have pressed the vinyl button on and off multiple times (no difference).
To be honest I have had platter problems with other controllers in the past (actually only the pioneer sx series) but I also have a backup pioneer sr2 which has NEVER had an issue. I just want a 4 channel controller than I can actually DJ on like I do with my CDJs or turntables…but so far no luck 
I am running 2018 macbook with recent OS and latest version of serato. Thx
