hello group


i realized that my maq 16 has a detuned cv output, while midi part is in 
perfect tune.
when i connect a synth with cv / gate and play a middle c on the maq
i tune the synth to c
now i play a higher c on the maq and its not in tune anymore (slightly 
lower then it should be)
when i play a lower note then the middle c it gets out of tune in the 
other direction (higher then it should be)
i tested it with 2 different synths with this result, and i also tested 
the synths itself with their own keyboards,
there it works just fine.
could this be a calibration problem of the maq16 ?
