Steppy LEDs

I'm sure this has been covered several times already - I'm in a tech heavy day with no time or screen to hunt it down - apologies for the repeat!

I have some house and some rental Rgb LEDs in, and all of them are very steppy looking over longer cues at low intensity.  The designer has seen them behave much more smoothly - Im wondering if my console may be putting out dmx oddly, or if there is a trick besides part cues or discrete timing, or if that's just the way LEDs are.  The house ones are x-focus, rental colour blasts, I'm on an ion with software version 2, and to the best of my knowledge no output/priority settings have been changed since we got it in 2009, and we have net3.  Any advice appreciated!

  • Hi Heather,

    The first question I would ask is whether they are patched as 8bit or 16bit, and secondly whether the drivers for the LEDs can handle 16-bit. If you're using 8-bit drivers then you will always get steppy fades, particularly at low levels. If you have 16-bit capable drivers, then make sure they're patched as 16-bit (basically 2 addresses per colour). That means the fade can be much smoother.

    All the best
