Hello. I apologize for my poor English. I would like to know: is it possible to use a keyboard on a projection with madmapper, and how to make it happen?

Is this question about Processing?

My understanding is that you send syphon to madmapper. So create a processing syphon sketch, and use the keyboard to draw text on an graphics buffer. Send the graphics with syphon to madmapper. (untested)
