a inductive distance sensor, optical sensors or vibration sensors for triggering would probably work better, the peizo’s had a hard time picking up the taps.<\/p>\n

also a good practice for quick foot movements or other musical tasks is foot wiggling if you can practice at home and resist the urge to do it in public untill you know how it looks. wiggle the big toe fast as you can to get better too sometimes it helps to put your smaller toe over the bigger toe. up and down toe\/heal tap or over the other knee side side to side(probably easiest to get fast musical recording movements with ?).<\/p>\n

updates later, basic midi note triggering.<\/p>\n

\/*
\nMIDI note player<\/p>\n

This sketch shows how to use the serial transmit pin (pin 1) to send MIDI note data.
\nIf this circuit is connected to a MIDI synth, it will play the notes
\nF#-0 (0x1E) to F#-5 (0x5A) in sequence.<\/p>\n

The circuit:
\n– digital in 1 connected to MIDI jack pin 5
\n– MIDI jack pin 2 connected to ground
\n– MIDI jack pin 4 connected to +5V through 220 ohm resistor
\n– Attach a MIDI cable to the jack, then to a MIDI synth, and play music.<\/p>\n
