The next rate down is that on every other DMX cycle a new step is output,
giving 1200 steps per minute. The next speed down from this is that on
every third cycle a step is output, giving 800 steps per minute. This is how
BPM’s of 2400, 1200, 800, 600 etc. are computed.
If a channel is to fade from 0% to 100% or 100% to 0% and every least
significant bit (LSB) which is the smallest level change a channel can make
then it will take just over 8 seconds for an 8 bit channel fade and over 27
seconds for a 16 bit channel. This is why many moving lights use smoothing
to give smooth pan and tilt movement.
These limitations are inherent problems in DMX.
