When it comes to combo streams I mean flow which in the cases I mentioned simply disappears after the end of the combo. In simpler terms, a stream that is smooth/rounded turns into a curve with the next combo.
You know, the problem with mapping this section is that the bass and drums play one simple rhythm, which would be tedious to repeat endlessly, the guitar has no bass endings and there are almost only long strokes. For this reason, I have to either map to bass and drums or to the guitar which would cause long sliders, and I'm not very good at making nice long sliders. I've tried to do some sort of guitar-bass-drums mix, but it still doesn't come out very well.
In my opinion, you could do something like this. It will add contrast and won't be confused with the stream. https://drive.google.com/file/d/1_j4uNFmEqa_EMaJH9wOgW-TBVSW9R1Pn/view?usp=sharing
The spinners at the beginning are well placed and this is a normal choice next to the sliders as it is a dragging sound with a clear hit on the HAT at the end. If you think there is bad timing here then I would recommend listening at 0.25% speed or checking your headphones, you may not have heard the ends on the spinners either. Later you wrote that the slider ignores the blue tick, but this is nothing wrong because ticks can be added, and this map is still in progress, and the blue tick is not as important as the red one. Only the last suggestion is correct, but I did it that way because I just didn't have any other idea for the sound there.
These sounds are a fast burst, in fact I think on a white-red-blue-red tick it sounds perfect. You know 1-2-3-4, not moving on to the next white tick. I think the burst should be set up that way everywhere.
