Yes, depending on the keyboard. I have an alesis micron, which can store patterns, and I'm pretty sure that I could put a MIDI on it to use as a pattern. I have also used an M-Audio USB to MIDI IN OUT cable plugged into an electric piano and used a program called MIDI-OX to play the file from the computer on the piano.
But he "don't write sh** cuz [he] ain't got time..." I don't know how you can say that is prolific artistry. Because, on this site, I must clarify, I listen to rap/hip-hop, but I have more respect for those who actually write ALL of their own material.
Or should I just play through it and hope that the drums or something cover it up when I go to record stuff?
Don't ever do this. This is a huge novice mistake and you will set your self up for mediocrity. The best thing you can do to not be sloppy when recording without completely cheating is to tie something around the nut or first fret that will let open strings ring, but will mute some unwanted fret noise.
evidence includes: my one friend hangs with them sometimes and when the douchebags girlfriend isnt around and its just him and my girlfriend, they act like a couple, she talks about him nonstop, he never says anything to his own girlfriend when there both around, and she follows hima round and listens to him (i faught with him one time and he told his girlfriend and mine not to talk to me. my girlfriend listened to him his didnt and he orders them around alot)
problem is i cant get his girlfriend to see it. everytime i bring it up she gets pissed because she goes to her boyfriend and he convinces her nothings going on
Theoretically, it shouldn't matter at all, but I think that some social reports have been done involving parental and familial influence, and it actually affects development a lot more than you would think.
A better drum program and some vocals wouldn't hurt, but it's still good. The recording quality is good for a one-man amateur project, the odd-times flow well, and it doesn't sound too much like genericore. You keep it interesting.
