Jack - More importantly, I do like the idea of holding down stylophone drones with the feet. I did draw up plans for a mounting of switches until I figured the easiest thing to do would be to solder the stylus wire direct to the keyboard & use the tuner to change the pitch. For now, the mp3 drones do the job just nicely.

Times like this I pine for my old electro shruti box...

WAV - You come along to Joe's Come-All-Ye next month and I promise you some traditional stylophony!
