I noticed that the gate length isn't correctly proportional to the step size (see connection software). This is a bit annoying, because although e.g. I can get a nice 75% (long) when step is set to 1/4, I can't make the sequence fast enough. Vice versa for the 1/32 setting: even "long" is much too short when the speed is at minimum.
Otherwise loving the Microbrute :-)
