Don't forget that the synth needs to see a pause after a pulse too - otherwise
we would count is only as one long pulse. So at least a 5ms pause is needed.
So theoretically from 0 to 100 in 1 second. But remember this is very dependent
on the synth scanning principle/speed!

Nice idea! Thanx!
This could be a scheme that tells the end of input and also offers a possibility
to cancel the saving:

1. First enter the code: 5 left, 3 right, 2 left, 4 right, 7 left
2. Enter number of milliseconds by turning right (==> 20ms = 20 right)
3a. End input and save with 1 left 1 right 
3b. End input and cancel without saving with 2 left
 
A nice addon would be a small piezo beeper that beeps once after step 1 (ready
for input) and twice when saved or beeps 4 times when input has been cancelled.

I should have a look for the code and start programming it on my own as my
friend stopped this project after the first prototype due to lack of time.

Ciao
