Machine to create melodies. It has 1 midi input and 1 output and is controlled by 2 rotary encoders and 3 potmeters. On a 16*2 character LCD screen you can see what you are doing. This way it is easy to add new functionality, without having to solder again. The software for this device is far from finished. At the moment it is possible to create simple monophonic melodies that can be used as bassline, but the final goal is to expand the functionality to more complex melody algorithms. Multiple algorithms must run simultaneously on their own midi channels. At the moment is also contains midi-LFOs, but i hardly use them: Prefer LFOs to be in the synth.

The rotary encoders produce a lot of bouncing during rotation, but i have written some code to compensate. It works rather simple: at rest, both contacts are in the same state (for example: both high). When rotating, one contact will change value first, followed by the second. When the rotation in finished, both contacts are in the opposite state. Which contact that switched first indicates the rotation direction. I measure which contact bounces first, and then block the input for a millisecond. Until now I have had no misinterpretations. Simple idea, and also effective.

The melobox contains 4 engines that work independently. It also has 4 LFOs, only the arpeggiator that i promised to make on the gameboy page is still missing.
