Dynamic plane separation in Jit.gen

Hello,

I'm working on a kind of spectrum visualiser. I'm using a multichannel FFT to get a range of signals at each frequency bin and display them in a kind of wave table form. In the jit.gen patch I had to separate each plane of the input matrix using the swiz operator but I'd like to be able to do this dynamically so I can use FFT's with higher resolutions without needing to add a bunch more swiz operators.

I tried using javascript but it slows down the render rate too much. Can it be done at all?

Thanks in advance!
