LED display to an Audio Click? Visual click track aid for drummers required.

Hi Folks, I'm searching for some info on how to make a visual "Click track" aid. In one of my bands, we use a click track on some tracks and live on others. I use a single in ear monitor for the click track which s fine for most tracks, but for some, I need the click fairly loud and this cannot be good for the old lugs long-term.

So, I want to make a small LED display or two that can react to an audio signal that is fed from the click track channel.

I've seen many instructables that show how to make LED blink/flash etc to music, but my requirements are a little different (I think).

The click at the beginning of each bar is higher in pitch and has a higher velocity compared to the other click in that bar, so for example;

Playing in 4/4 time signature:

click 1 - Velocity =100 - pitch C5
click 2 - Velocity =90 - pitch C4
click 3 - Velocity =90 - pitch C4
click 4 - Velocity =90 - pitch C4

If playing in another time signatures ie; 3/4 or 6/8, then I would also need to cater for this in the display

Questions:

1. Does anyone know how I could devise a system that would light a Red led for beat 1 and then perhaps a white (or other colour) led for the rest of the beats, but in a sequential fashion? 1,2,3,4.

2. Is it possible to change which led flashes based on either pitch or velocity?

I could even make the front of the led display show actual numbers over a perspex cover so at anytime, a quick glance will show me exactly where I am in the bar. So rather than coloured leds.

So to recap, I'd like to be able to take an additional audio feed from the click track channel from a mixer, into this new "drummers visual click track aid" device and have it react to the clicktrack and display that in the form of beats per bar based on either pitch or velocity of the click track. I currently use a couple of wood block sounds for the click track because they are very clean and short.

Many thanks for taking the time to read through my requests and if you're the kind of clever person who could make such a device, I'd be more than happy to pay you for your input and suggestions.

Many thanks in advance and I look forward to hearing from you soon.

Cheers
Phill
