Hi Guys, newbie, but a tinkerer nonetheless..
Trying to add hi bright leds to my ART X-15 MIDI foot controller, and garbled signals/voltages everywhere...
here's the schematic link...

Sucessfully added them to my X-11 controller a while ago w/no resistor mods/no probs...
This one seems to have a different LED array, and I know I probably need to swap out (or Parallel) resistors to get the right voltage to them...
However, the schem is confusing (to me anyway!) as far as the forward current goes...it looks to me as if the transistors supply the voltage directly to the leds... the resistor array near the top of the schem seem to come after the led..
I hate being a newbie, I've done so many hack mods, one day I'll actually learn what I'm doing...
Any quick expert help would be great, this is very very urgent!
Thx heaps guys..
