Is there anyway to futz with how interp is handled?

Right now I have a 7 x 12 matrix, where each cell is mapped to a Midi Note with its own color. If interp is OFF, the display looks too blocky and boring, and when interp is ON the cells blur TOO much…

Is there anyways to regulate the amount of interpolation that Jitter applies? I want something to blur the entire matrix so it looks more interesting, but I want to be able to control that amount. If this is covered in the tuts just let me know. I am only up to #12. Thanks!
