Reply to Help with itch beatgrids on macbook pro

hey guys , I need help with adjusting beat grids, I have a macbook pro with the ns6 controller using itch 1.8. I analyzed files with auto bpm, but it seams there is more adjusting needed because i find most beatgrids are off using sync function when mixing, I then have to speed up to match as best i can before transition to the next cut. I been looking for more tutorials on beatmatching but havent found anything thats explains specifically on adjusting beatgrids with a mac , especially need help with keyboard or mouse commands and what needed to adjust beatgrids, i tried to adjust beat grids on certain point of the track were the beats are off but everything seems to move to the left or right , and some times i am only trying to move a couple of the beats over, I no everybody has there own way and some dont use beat matching but I am one that wants to use it and hopeing you guys that are more familiar with beat matching can help me, if anyone can provide a start to finish of a newly enter song what they would do from first analizing to adjusting beat grids when itch does not analize them as best as they can be, i would appreciate it,
