might help to post a clip of what your doing that you don't like, so we know what you mean by "not clean and realistic".
Those terms are very abstract. Like when you say clean, it makes it sound like you either using drive or distortion, or sample rate reduction or maybe a waveform other than sine. It doesn't get any cleaner than a sine wave, so I would start there and tweak the envelope (amp and pitch), then try some of the transient samples for the clicky / drumstick strike part of the sound.
When you say "not realistic" is also a very subjective terms. I mean its a drum synth made to model analog drum synths in some ways, realistic isn't really the point.
Your question is a little vague and confusing, which makes it hard to answer. Make sense?
