I have been using msp for a while but I just started learning jitter about a month ago. I am going over the tutorials (I still have max7) and I've spent days trying to figure out one specific thing in tutorial patch 18 (iterative processes and matrix re-sampling). I understand the patch but I am trying to have control over the "pixel tail" and I can't do that. If you set feedback at 1 the pixel tail will always tend to move toward the bottom right corner. I have tried numerous things, obviously changing the jit.streak direction and messing with all parameters, but I am starting to think it has something to do with the re-sampling. If you bypass the re-sampling matrix (jit.matrix 4 char 320 240) and then change the jit.streak direction it responds the way I want it but I end up (obviously) with a low res video (a 20x20 matrix considering you didn't change the default settings) and also when I unplug the jit.streak completely, I see that the pixel tail always tends to go to the bottom right corner. 

Is there a way to have the original patch (including the re-sampling and jit.streak -because I like that visual effect and want to use it in a video) but also to have control of the "pixel tail". 

Ps. I attach the original tutorial 18 patch

I also think it might be that (I assume) jitter reads matrices from left to right top to bottom and when doing the feedback loop and scanning the matrix for the previous frame, the tail tends to go to that direction. Would this be it? if so, there a way to tell jitter to do the feedback scan in a different direction?

just shove a jit.rota in there and you can control the direction of the trail using the offset attributes:
