Hi everyone

So a few month ago I decided that I wanted to change my gear and I thought about getting turnable but it's too expensive so I thought abour buying a numark V7 to scratch but the problem is that the numark V7 is made for serato and I'm using traktor pro, and I saw on other community that with traktor pro the platter was not turning

So if there is people here who are using a numark V7 with traktor my questions is :
Is there mapping for traktor ?
Is there a way to make the platter turn ?
Should I get traktor scratch with the A6 soundcard (better than traktor pro for scratching ?) ?

Thanks

(sorry for my english I'm French )
