What you can do is record a sequence from the keyboard on your mpc (midi sequence, not actual sound) and save it on a track. create as many different tracks as you like (make sure your midi channels correspond with the different sounds from keyboard) and get the sound coming out of your mixer. get some 1/4 inch cables and plug the output of the mixer into the record in of the mpc. on the main screen solo track 1. set the number of bars 1 number higher than actual number of bars so when your record it does not loop. record your sequence from track 1, name, assign to pad on a new program, and save. Then Do the same with the next track, etc etc. If you have not upgraded your memory, try to stick with 2-16 bar loops, considering you will not be able to record your whole song in one go. If you have 6 tracks and run out of memory after track 2. make sure your new samples and programs and midi sequence is saved, and restart your mpc. then load all previous data and start recding from where you left off. then play your new samples and make some fresh tracks.
