Readme
To run the program, simply open the Max/Jitter Patch.
The images have to be in the same folder as the patch!
In the upper left corner, you can select the source of the MIDI signal, a list of detected devices will help you find the one you are looking for.
At the top, but more to the middle, there is a second toggle, turn it on if your MIDI device/synthesizer starts numbering the instruments with ”1″, turn it off if the numbering starts at ”0″
Press “ESCAPE” to toggle the fullscreen mode of the display and start playing!
(There is an additional display integrated into the patch, you can pretty much ignore it )
