Pattern chop with a feedback logic

Hi There,

I am curious about how can i create a pattern, that is constantly updating and the first sample value is defining the next one (like a feedback loop). For example, a pattern that has 5 samples: (1,1,1,1,1). I modify the first sample, so the new is .9 (.9,1,1,1,1). At the next frame it should modify the pattern like this: (.9,.9,1,1,1). The next frame like: (.9,.9,.9,1,1). I assume it requires some magic with extend chop, but the operator snippets was not enough this time. Thank you for your help in advance!

Wondering if the Phaser CHOP might be what you are looking for.
