[sdiy] Filter cut off DAC

[Roman Sowa]

Do it 12 bit. All you need is resolution enough not to notice 
quantization during parameter settings. Regardless if it's just cutoff 
on that DAC, or combined with LFO and envelope, it's still the same 
amount of filter frequency quantization, so if one cannot notice it on 
turning cutoff knob, it will not be noticeable with other modulation 
sources added either.
And if you need smooth - just add simple analog filter after the DAC. 
Like 200Hz or so.
