OK, just an update. Got the application working pretty well last night, and I was happy with the operation of the laser harp code. The kits will ship EMS to csshih tomorrow, so they should be in your hands very soon!
It's not added quite yet, but we will also be adding a feature that will let you set the play velocity as well :) It has already been programmed onto your microcontrollers, and I can tell you how to set it manually if you need it right away, but I intend on adding it very soon anyway.
Here is a view of the simplified GUI :)
