[sdiy] Software to log frequency every x seconds?

[Grant Richter]

Thank you for re-enforcing my point. Since this is "synth-diy" the  
assumption is the target audience is musicians.

The relationship between frequency and pitch is subjective and  
affected by many factors.

That is why an instrument targeted to the specific sensory axis (a  
chromatic tuner) is going to produce more useful information.

Frequency counters can respond to musically spurious information like  
RF switching noise on transients and resets. These extra counts act  
as "sensor ghosts" which are misleading.

Because of this, the frequency counter information is more likely to  
be misleading about useful music performance.

Engineering schools produce a fixed set of "orthodoxy" which  
engineers are reluctant to deviate from. This represents an  
"opportunity cost" for the engineer.

Using the methodology of the target user group is more productive.
