HI! I built a 10x10 matrix using the adafruit matrix sample script and it scrolls "Howdy" 3 times in different colors, as expected.But if I change the text (I just typed 1234567890) it stops half the 8th letter and restarts with the 1st in the next color.Whats the problem?

Are you sure you put in the capacitor the right way? All others connect ground to ground and positive to the reset pin of Arduino.Its not a good way to connect three LEDs to one limiting resitor on the ground pin. Better way is to put a seperate resistor to the positive side of each LED.

How have you built this without NPN transistors to switch on and off the layers?I tested your code with my previously built cube (including 4 NPNs) and it works.

Awsome project, but I can't compile the code...I always get the Message:fix_fft.h: No such file or directory#include <fix_fft.h>(in some of your sketches its a different library but the same problem..)Where can i get those libraries and how can I import them?For example:I found <fix_fft.h> at GitHub in raw code but not as a .zip file.https://github.com/Robmaister/LEDMusicVisualizer/b...How can I get it running as a library.
