[sdiy] Detuning in Digital

[Matthew Smith]

Veronica, Achim, thanks.

Now I know that logarithms are involved, I will most certainly be using 
lookup tables! (Even if I were doing this on a fast-clocked ARM, I'd use 
lookup tables for at least part of the math.)

I guess the question I should really be asking is how do older DCOs 
handle pitch bend - because I bet they aren't doing any heavy 
number-crunching.

Note: it's pitch bend or frequency modulation in which I am interested, 
as opposed to "master detune." The latter is easy - just change the 
clock rate to the whole system (apart from the UART handling MIDI in) 
and not worry about values - it's a bit up, or a bit down.

Cheers

M
