Of course there is more to it than that...
even with the extremely careful and tedious attempts, your homemade wav will never be perfect... unless, of course, you know something that i dont. however, there are subtle tricks you can perform to enhance your quality and essentially give the illusion of a more perfect wave. Now dont get me wrong, i take great pains in sculpting it as best a copy as Im capable, but its never perfect. (In fact, your model is probably not perfect, as even digital representations of analogue synths carry their own blueprint, which gives character to each synth. the retro synths are very warm and much desired.) As far as percussion goes, it isnt actually necessary to get it completely perfect... but as far as like, say, the 3 acid sections of this track, the copy job is more noticable, and flaws are enhanced. So you mold a good sin wave and import it into a sampler and write percussion as you would analogue. you control the sample pitch with the mod envelope (or whatever envelope) and throw some crispy distortion, and you could make some good percussion as you would with any synth. And your copy job would matter less as the influence of pitch and careful distortion would define the nature of the sound so much. (but of course not completely) And then adjust your amp env according to which drum your writing and go to town. Im assuming you know how to write an analogue bass drum, snare, hi hats etc?.. also if you add voice with nothing detuned and mostly dry, that can enhance the sound, i do that quite often. . Actually pitch can go a long way in helping more than just percussion, its the subtle details that add up. It's also important to know that the quicker the sample is, the less obvious of flaws, well... some of the time anyway, not in every case. It would actually be fun to demonstrate these things on video or something. There's too much ground to cover with mere botb posts. It's good to have a good sound editing program with mucho features and abilities, because you find yourself finding uses for these things you never knew would help. Also on a side note, adjusting your stereo field for each sampler (or synth outside of botb) in your track is important in relation to sequencing, because a moment can get too crowded in your track, and depending on taste you can give your drums a wide range and leave the melody or harmony in the middle, as you would vocals, or vice versa, or whatever. I myself am guilty of overcrowding alot. anyway i digress... I have to stop myself as i could go on and on into the void...
