I use an NS7FX also. Are you experiencing any issues with the platters since you did this? If not, I’d say you’re fine. You’re going to have to place resistance on the platter anyway when pulling or pushing the record when beatmatching anyway.
The best source of information for using the NS7FX and ITCH software are the manuals. Read those front and back, that’ll give you a great foundation for understanding each component and how they relate to one another. If you’re talking about mixing techniques using the NS7FX, that’s another topic entirely.
Great to see another NS7FX user, though! And welcome!
