I have an 88 key piano and I set the visualizer to 144. It is 144 leds and it is the WS281X led strip

I get the below array index error. it seems to only happen on the far keys, past the light strip. Shouldn't the LED setting I set, set that limit properly?

I don't understand the usage of the offsets, but I have light number 92 = offset 2, 55 = offset 1. These were just defaults i think
