Moppy is a M_usical Fl_oppy controller program built for the Ardiuno UNO.

--INSTALLATION--
The Arduino code requires the TimeOne library available here: http://www.arduino.cc/playground/Code/Timer1

You will need to follow the directions in the appropriate Java/SerialDrivers folder for your system to install the serial drivers prior to running Moppy.

Upload the included Arduino code to the Arduino of your choice, and open up the included Java code in your favorite IDE.  This code includes a NetBeans project for your convenience, so you should be able to open the project directly in NetBeans.

--HARDWARE--

I built Moppy using an Arduino UNO, though it should work just fine on most Arduinos.  The pins are connected in pairs to floppy drives as follows: Even pins (2,4,6...) are connected to the drive's STEP pin, the matching odd pins (3,5,7...) are connected to the drive's DIRECTION control pin.

Some pinout information can be found here: http://pinouts.ru/Storage/InternalDisk_pinout.shtml

Make sure you ground the correct drive-select pin, or the drive won't respond to any input.  You can tell when you have the right drive selected, because the light on the front of the drive will come on.  Also, it's VERY IMPORTANT that your Arduino is grounded with the drives, or the drives will not register the pulses correctly.


--CONFIGURAITON / USE--

- Open up the code in NetBeans (or your favorite IDE) and run it.  Alternatively, you can build the MoppyDesk.jar file and run that.
- Select the COM port that the Arduino is hooked up to from the "Arduino Port" drop-down.  You will need to have this configured before you launch MoppyDesk.
- Click the "Connect" button to create a new Sequencer connected to the specified COM port.
- Click the "Load Sequence" button and select a suitable MIDI file (see below).
- Click "Start" to start playback (if all goes well).  
- The Stop/Reset button will stop playback and reset the drives.  Pressing "Start" again will resume from where the sequencer left off.  You will need to reload the MIDI to start from the beginning.


--MIDI FILE INFORMATION / GUIDELINES--

- MIDI files should have one MIDI channel for each controller pin on the Arduino.  Channel 1 will be sent to pin2, channel 2 to pin4, &c.
- Each drive can only play a single note at a time.
- The software will only attempt to play notes between C1 and B4.  Floppy drives don't seem to respond well to notes outside of this range (especially higher).
- Generally shorter notes tend to sound better, as longer notes are marred by the read-heads changing directions repeatedly.




Cross your fingers, and enjoy!
