Just for clarity, I wasn’t advocating more sequences - there are enough for me. My comments on midi were just that @Swingmix was looking for more clips, so I suggested a source for him.
You are quite right about the unpredictability of where a useful sequence might originate from. My central point is that of frogs and princes, and how you find the golden needle in the haystack (much mixing of metaphors here…)
So if I’m into (say) trance, that might be a logical place to start rather than jazz, to try and get some rationale in to the auditioning issue. I guess randomly choosing some sequence is also valid, and maybe more creative. I was just underlining its the sheer scale of the choices one is faced with that can be a problem.
So, what do you start from when you sit down in front of the PC ?
