Sequence Quality Not Good

I have some WAVE FILE samples. We already sequence the songs with this WAVE FILES.But we cannot get the good quality for the KICK DRUM,SNARE,HI HATS-OPEN AND CLOSE and Indian Etinic Instrument.No quality for the out.

If you want i can send the sequence sample and tone sample.Some of the samples from SPD20.

Any chance to get the full punch for this tones ? We already try all options.But no chance.Where did i can bye the original Drum kit and Indian etinic tones ?

Waiting for your reply

Its a sampler therefore you have to sample better sounds.
Put in bad sounds you get bad output from MPC. Put in good sounds then get good result. Do you understand that? Seemslike your from India or somewhere? O and try reading the manual, thats allways a good start.
