Im pretty new to software daw and ive been going back and fourth to guitar center trying to figure it alongside with alot of youtube tutorial videos and i just cant get it ..So this is my scenario i have an mpc 2500 that i am currently using with an m audio track plus . I have my Midi out B on my mpc hooked up to the in on the interface ..I have the Midi in on my Mpc hooked up to the midi out of the interface ...When i hit a pad it registers that there is sound going through the interface....Ive tried everything to hook this up to Logic pro x..Ive watched videos ive followed the support tutorial instructions ..i set everything up like they did and for literally 10 minutes i was able to use my mpc as a slave so i can hit record in logic and the mpc will start its record but when i hit the pads no sounds would record in logic... I want to be able to take my samples and songs off my mpc and record /edit them in logic.. i have all my preloaded sounds that i want to use right now in my mpc..Please Help Me!
