By gating I mean : momentary set the level of any controller to zero while you hold the gate button pressed, and back to normal when you release it.  Well, you have buttons on many MIDI surfaces out there but they never gate the output of another controler; they just transmit their own value and you have to program the gating by yourself - quite hard (not to say "impossible") in most cases. On the Arkade, the gate button just ... gates, whichever sensor you're touching ! +  * ... anything that could be missing on any midi controler, like a simple MIDI-gating button (labeled "Freeze/Cut" on the Arkade).

-  * Adapting some of the sensors to the MBHP platform needed some conditionning (use of caps, resistors, many values were tried to find the right ones). The response curve of Sharp's IR distance sensors is logarithmic; I've linearized them in a software way but you could also find a way to have hardware linearization (I'm interrested by the diagram if you find this 8-)). Anyway, the software linearization doesn't require that much CPU and they're still very reactive ;-). I'll post some of the sensor conditionning tips (components & values) later on.+  * Adapting some of the sensors to the MBHP platform needed some conditionning (use of caps, resistors, many values were tried to find the right ones).
