Question: How to add LEDs to extra buttons on modded MF Classic? Posted on: 19.09.2013 by Lavenia Markwell A while back, I modded my MidiFighter Classic by adding 4 more Sanwa arcade buttons and 4 Bourns faders. I built a custom walnut and maple box with a friend and hand-drilled all the holes in the top plate. Finally, I fashioned it with maps of my hometown, Cincinnati.One feature that is missing... LEDs for the 4 extra buttons on the top right. My question(s) for the more experienced modders = what is the best LED to use? and what is the best way to wire them up to show the on/off status of the buttons? Here is a pic of the MFC. | |

| Olimpia Briden 20.09.2013 | as far as I can see, you would need to add a 2nd tlc5928 into the circuit somehow and then change the firmware source code so that it can address those leds, although I could be wrong. |

| Olimpia Briden 20.09.2013 | As they're wired directly to the 5v and the + side of the button, no, you won't get any midi feedback from them. They'll just be off when a button isn't being pressed and on when it is. As far as I know, there isn't any simple way to add more leds with midi feedback into the midifighter, without adding extra chips. |

s.com/showthr...l=1#post287998 Just get some 3 volt LEDs and some 0.25watt 220ohm resistors, 1Kohm if you want them a bit dimmer. I know that the units are running 5 volts but the resistor restricts the amount of current going through the LED so it won't burn out. |
