How Do I Erase old BULLSH*T????

I am in the midst of making a nice lil beat on the 1000 along with a lil sample I made mah damn self in a keyboard. I have now loaded it onto the MPC, but there is not enough memory in the card to save the sample (Not the sequence). I would like to erase some old sequences that I saved onto the MPC under the memory card. How do I do so? Or what options do I have to save the sample.

F.Y.I. I already recieved a memory card 128 junt..

I don't know if this is the right way but what I do is plug the mpc into my computer via usb then delete my unwanted files like that.

Good Lookini out fam, Im about to try that shit..

yeah its how u do it well its how i do it

yeh just back up to the pc you dont have to delete older files to save space. usb is your friend
