Interfacing ardcore and quneo

Ardcore is brilliant, but the panel restricts the sort of sketches that
can be effectively controlled.

So-- I have a quneo, which can output regular midi. The LEDS on the queneo
can be controlled by sending midi to it.

I've interfaced it directly with the ardcore-- an ardcore sketch is receiving midi
via A2, and sending midi from D0, using the Software Serial library.

I've got DIN midi to/from the quneo through the KMI midi expander, through an arduino midi shield and
into 2 mini jack sockets. The shield is being powered by another arduino, but it's not involved.

The sketch is a simple 16 step trigger sequencer, using clkIn for the rate, and d0 for
the output. The sequencer can be stopped/started/reset and the direction can be reversed.

Quneo pads turn individual steps on or off. The are used to stop/start and reset, and the
first pair of horizontal buttons are used to set the direction.


The quneo preset I'm using disables a lot of the midi data the quneo can send-- otherwise it seems
to pretty easily overwhelm the software serial library. I found it convenient to get the
controller to send the same notes as it uses for remote led control. Local leds have also been

At some point I want a simple box that has 2 midi din connectors and
the little bits necessary to put the midi serial data to 2 mini jacks; but from what I understand
it looks like it will need it's own 5v power source? I was hoping to get away with wiring a
MIDI din socket to a mini jack socket but that doesn't seem to work.

There's lots of possibilities with this. The quneo itself has a grid mode which makes each corner
of the pads active-- so it's an 8x8 grid controller. The ardcore could easily allow selecting of
different layers too.

Time to look at meadow physics again.
