what i'm ultimately trying to learn is volume swells and how to pan a sample from Left to right
Not sure if you mean you want to automate the pan of sample, if that is what you're refering to then............
Go into the Mixer screen> press the SETUP soft key(F5)> change Record mix changes: to YES. Now the MPC will record any pan or level changes you make in the mix screen in real time. You can also program the pan in step edit, easier if you need fast ping pong type panning fx.
also.... i have a shaker recorded on 2 tracks....the same exact sound, but i want one to play through the verse, and both to play through the chorus....and i want one to pan more right and one to pan more left
Go into the Program assign screen and assign the shaker to two differnt pads and pan them accordingly in the mixer screen.
