Hey yo
Just buy a cheap CondenserMic and put it into your MPC and record stuff like tapping on a desk with your fingers ( just an example). You will get interesting sounds and you can edit them. This will give you a lot of nu ideas!
But its also good to have a wide range of sounds, so i would also suggest to take samples from electronic drum modules or keyboards.
I hope it helped you a bit
You can also send me an PM with your emailadress and i will send you some Sounds
ok?
Phil
