All CS80 Factory patches tuned to 0.9993 .

[jeffbart]

The default value for the master 'TUNE' (on double clicking) is 0.9993, not 1.0000
[see PRIOR ISSUE http://forum.arturia.com/index.php?topic=87710.0 ]
I checked many random Factory patches, they all read 0.9993 for master tune value.
I would guess this implies the entire library is flat? 
A quick check using Mini V3 a440 tone, sine wave in CS80 and ears confirms CS80 powers up flat.
In fact, if the Mini V3 a440 tone and my ears are to be trusted, then true a440 ( 8', A above middle C) on the CS80 sounds like it is actually somewhere around 1.0007.

Please can this be checked? It appears CS80 tuned to 1.0000 is not really a440, and all the patches are flat anyway. I may be wrong!

Cheers Jeff

Using the Tune utility in Logic the factory presets saw, sinusoid,, square, and triangle are all -2 cents.
