some setup diagrams

• Diagram sources are in http://plantuml.com format. Unfortunately a bit of a hack to incorporate them in github (https://stackoverflow.com/questions/32203610/how-to-integrate-uml-diagrams-into-gitlab-or-github), but at least the sources are inhere as well.
• i tried to generalize using an external clock and midimerge vs using an SBX, see if you like it :).

Thanks for the diagram! However, I think the midi merge needs to be between the Launchpad and synth. The easiest setup is for Hachi to get the external clock from the Launchpad's midi in. Then all of Hachi's output goes out the Launchpad's midi out. If you want the synth to also get clock, that's where you'd have to merge the output from Hachi/Launchpad with the clock source.

There is another path, where the clock comes in to the RPi via USB (which is why I recently separated the midi in and out in the Hachi config), but you'd still need the merge.

With an SBX-1, you can plug it into the RPi via USB and have Hachi follow its clock. Then you send the midi out of the Launchpad into the midi in of the SBX-1 and let it merge that signal with its own clock. It works great, but I'm not sure how many other devices would support it. I'll try to make a diagram!
