Hi tuners,

Recently I calculated the frequencies for a standard quarter comma
meantone scale with Scala. Scala shows 437.3989 Hz for the tone A. I
expected it to give 440 Hz. Until now, I thought that A was always
440 Hz nowadays, independent of the tuning. But since my Scala
experiment I am not sure about that.

Part of params.par looks like:

[-------------------------------------
! Default frequency of middle C in Hz:
261.625565301
-------------------------------------]

so, according to Scala, it is middle C that always has the same
frequency. And A is only equal to 440 Hz in 12 EDO.

I find this very strange. Does anyone know whether this is right ?

I used the following coomands to calculate the frequencies:

[-------------------------------------
calculate 3/2-$k^1/4
pythagorean
12
2/1
7
$0
3
show /frequency
-------------------------------------]

I use Scala version 1.41 for DOS. Maybe that's an old one ?
