Here you can see my midibox project. A 3 oktave Acarde Push Button Style controller with mixer section.
It took me about 2 month to build it. Thanks for this great project that makes it possible for me to build that thing.
Cool Knobs! Cool project! What are you going to control with? Any special apps or general purpose?
I use it as a live toy to combine drum patterns and mix them.
The black knobs are to equalize with kill switches.
