Introduction

The PROPHET64-Midi-Interface is a simple Midi-Interface that makes it possible to syncronize your 
Prophet64 software on your Commodore64 with every Midi-Clock-Capable device such as a sequencer or a drum-machine.



Do It Yourself

It's very easy to built your own PROPHET64-Midi-Interface with the provided schematics from the 
project-page (http://www.firestarter-music.de/prophet/).
You don't need any power-supply as the circuit uses your Commodore64 as power-source.

********* Take care that you check your circuit twice and also ***** 
********* that your connection to the userport is 100% ok, as ****** 
********* the internal fuse of the Commodore64 could get *********** 
********* damaged if there's something wrong!!! ********************

The view of the userport-connector in the provided schematics is to the 
soldering side of the userport-connector (looking at the C64).



Function

When turning your C64 on, the LED should flash twice and turns off. After Receiving a Midi-Start or Midi-Continue commando 
the LED should turn on and your interface should syncronize the PROPHET64 software to your Midi-Source. 
After receiving a Midi-Stop, it should stop syncronizing and the LED should also turn off.
All other Midi-Data is filtered.
