	Minimum parts needed: (new parts in bold. see parts list for details) Prototyping board (breadboard) Power supply connector 5-15VDC power supply Assorted wires 5V regulator PIC 18F452 or BX-24 Serial cable DB9 female serial connector & headers 5 pin DIN female connector (MIDI connector) 2N2222 (NPN2222) transistor 7404 Hex Inverter (PIC only) LED's Switch Variable resistor 10Kohm resistors 220 ohm resistors Step 1: Connect a MIDI out circuit to your microcontroller as shown in the PIC MIDI notes or the BX-24 MIDI notes.
	Step 2: Connect an analog sensor to one of the ADC pins of the BX-24 and use it to generate a value from 36 to 96. Put it in a variable called something useful like noteVar. Confirm that noteVar is actually changing reliably when you affect the sensor, using a debug statement.
	Step 4: Connect your MIDI circuit to a MIDI synthesizer and hear what happens.
	Step 5: Make a MIDI instrument using an analog sensor or a variety of analog sensors as input.
