Agreed. I use a crossfade IPCB fader as an inhib. But when bringing the fader down, LEDs can do some odd color jumping, not a smooth crossfade. My current workaround is to fade the fader up, then make the Flash button a 'release' with 3.5 seconds, to smoothly crossfade back.
Would love a 'latching' type option for flash to assert/release a IPCB fader.
