It's out of tune, at 0.500 it's a little flatter than A440. It's close to A440 around 0.516.
And, when I get a patch with the voices in 'init' state, no mod of any kind, no detuning of any kind, each one of the voices can sometimes be a little flat or sharp by a cent or two. Just had it against a tuner in Logic. On 'Rotate', the voices are not quite in tune with each other. Hard to hear, but you can meter it.
I can live with the internal 'out of tune' (though I have no idea how this can happen in software..) but i would really like the master tune knob to be at A440 when it's dead in the middle at 0.500

[UPDATE] I tested using 'template single'. In the 'Voices' page, all detuning was set to '0'. But, after moving each one up and down and back to '0', the internal tuning seemed to fix itself. It is as if the detuning settings were not accurately called up, until manually overridden. I"ve saved it as a user template, and it recalls in tune (with itself, but still flat compared to A440)
