I probably have a different way of constructing percussion tracks to most folks, because i don't really construct them, i de-construct them. No, actually, it's probably about half and half to be strictly accurate.
What i do is randomly hit the notes on the keyboard untill the bar or however long i want to record is up and then i just use the notes i think sound good. I will make adjustments here and there to make things fit and i'll quantize it 100% so notes will naturally begin to fit into the timing of the track.
Then i'll try various sounds and i'll detune the track sometimes to make sure i'm using the sounds i want to. I'd say that at least 50% of my percussion tracks involve selection and judgement rather than painstaiking construction.
I also use multiple percusion tracks to create layers, sometimes using the same pattern, but detuned or shifted or even edited if i'm feeling adventurous.
As i understand it, this is the complete opposite to how Sean creates his drum tracks. He enters his notes one by one, but i just would'nt have the patience for that cause i'm a lazy sod.
I've always used this method from day one of using P5 and it seems to have served me well thus far so i expect i'll carry on using it. I think my method helps me create patterns i would'ny ordinarily have thought of myself or anyone else for that matter.
I don't know if i've described that very well, but i think it gives the general idea.
