How does positional sensing work?

Does the PS algorithm use some kind of ratio between the rim sensor and the head sensor?

I have never been successful getting PS to work well and after much work tonight I think it comes down to the trigger design or mounting.

I have a Jobeky AI centered mounted trigger. This is essentially a single bar mounted to lugs with the head sensor mounted in the middle. There is a rim sensor as well. https://jobekydrums.co.uk/product/jobek ... er-system/

Now picture a clock (analog) with the trigger bar across the face going from the 9:00 to 3:00. If I hit anywhere above the bar along the line between 9:00 to 3:00 I can’t get the off center sound to trigger. If I hit really close to the rim I can get the edge to trigger but once I get about 30-40mm away for the edge it completely skips the off center range and goes straight to center.

Now if I hit above an imaginary line between 12:00 and 6:00 things work great from a positional sensing standpoint. Edge, off center and center rings are nice and wide.

I figure if I understand the PS algorithm and how it determines the signals I may be able to adjust my trigger to make it work.

The positional sensing method eDRUMin uses is complex. It does not rely on the rim sensor at all. Instead it does waveform analysis. As I said in the other thread, send me some data so I can see what's going on and modify my analysis. I'll contact you via email.

Sent. But a large part of the issue could be me. Hopefully you can give me some insight after you analyze the files.
