The Max user interface becomes rather slow when I use the spectrogram object in sonogram mode. I'm curious why this happens since I would expect that displaying the sonogram is not a lot of drawing work (I'm not even using the scrolling mode).
The patch below has two rather large sonogram objects. When I change the number box that controls the frequency of cycle~ with the mouse I'm getting slow update rates (around 180 ms). I'm curious to know if this can be resolved. (max 6.1.3 on 10.8.5)
