Some questions

[Skirmitt]

I'm making a clone of the Midifighter for my project. I see in the movies that in 4 bank mode you can press the active bank button to keep the effects going.
All the leds keep burning, is that something the firmware does or is this a mapping feature ?

Except for the supercombo buttons, are there more special features you need to implement in a clone ?

What I will do is the leds and the 4 bank mode with all the notes I found on the forum.

the led blow because you don't have any decent current limiting resistor in series, as simple as that

Who said the leds blow ? I mean what triggers the leds...

Heya Skirmitt,

Yes the behavior you are describing is firmware based, this is how it behaves in four banks mode.
