The [<googa>http://www.akaipro.com/product/apc-mini |Akai APC Mini] </googa> is well suited for use as a Midi controller for Box Of Stops.
The large grid of 64 buttons can respond in Green, Yellow and Red, to show the different [[Bank|banks]] in Box Of Stops. And the nine sliders at the bottom can be assigned as volume controls for the banks and [[Master volume|master volume]]. For example, the ability to balance pedals is surprisingly useful.
* Each [[Bank|bank]] is assigned a column of buttons on the main 8x8 grid
** The banks rotate in sequence between Green, Yellow and Red
** The order of the banks is the same [[Bank#Reordering banks|as normal]]
** If there are more than 8 [[Stop|stops]] in a bank, they wrap to the next column
** A gap is left between each bank, unless there are simply too many [[Bank|banks]] or [[Stop|stops]]
Here the fifth stop on the Swell (in Yellow) has been moved and also the first Pedal stop (in Red). The remaining stops automatically line up after the one that has been moved.
== Timeout =={{timeout|APC}}
After 10 minutes of inactivity, Box Of Stops will automatically timeout the lights on the APC.== Other controllers ==
It will wake up again when activity is next detected. This could be anything, e.g. For a button on the APCcheaper Midi controller that also offers feedback lights, or a note being pressed on a keyboard. If you wish to change the 10 minute defaultand sliders, please look for see the details about the <code>midi.timeout.minutes</code> value in [[Application propertiesKorg nanoKONTROL2]]. == Other controllers ==
Please At a much simpler level, there is also see the details about option of using the [[Korg nanoKONTROL2Status Board]]from The Pi Hut. This plugs directly into the [[Gpio button|Gpio connector]] on the Raspberry Pi.
