Correct, and the number of bands is configurable with (set-num-frequency-bins) > Second, if I use a gh in a colour or rotate statement, the rotate > magnitudes are great and the colour swings are minimal.

Maybe I'm missing something... It might be useful to have a normalised version of (gh) - I seem to remember this existing at one point? cheers, dave
