So, this setup is pretty much the same as in the other videos, only instead of routing the midi through my arduinoboy, I’m just using the QuadraSID VST inside Ableton Live. I had also modified the software a little bit since last time, meaning that the scale which the wii guitar plays is now determined by the midi notes being recieved by the software.
I’m pretty sure most resistor values would work alright in place of the 10Ks, but if I’m wrong, then… tough. They’re just acting as pulldown resistors anyway. The value for the resistors marked with a question mark depends on the current required by your LEDs.
Code
Here is the code which needs to go on your Arduino board, and also the code for the Processing app which converts the serial data to midi. The Processing app requires the rwmidi library, which you can get here.
So, you want to make an awesome chip cover of your favourite song, but you suck at picking out notes by ear, oh no! Luckily theres a few ways to “cheat”, such as by working from guitar tab or midi file.
That being said, just running the midi file through your vst of choice will likely sound like crap, as will copying straight from the guitar tab. That’s why I’ve decided to write this:
