Title: Only flash LED every four steps for correct 100/1K/10K flashes

With the improved encoder resolution, the LED would flash every 25 Hz/250 Hz/2.5 KHz step which is too frequently to be helpful. The patch flashes the LED only every fourth frequency change, corresponding to the original 100Hz/1kHz/10kHz step sizes.
