Hi See attached patch. Open it, turn on DSP, click the toggle and compare CPU usage with the subpatch visible or hidden. On my computer, Pd takes 1% of CPU with the non-visible slider, and between 2 and 3% when the slider is visible. Remember that [bang~] bangs at audio rate :) I usually limit slider and al refresh request rate to 20ms or more : or better, once the patch runs ok, i delete all useless sliders, bangs and toggles.
