Broken VCO1 only on Square Wave

[arthur_antoine]

When i play an init patch, six notes in a row with a square on VCO1, the 3rd note doesnt play...!
The other waveforms work fine.

I calibrated everything several times, sometimes with success and sometimes with a timeout failure.
Downgraded the firmware to 1. But all with the same outcome, no 3rd voice being played.
So i am afraid this is a hardware issue 

Has anyone experienced this too?

I've had contact with support during the holidays to perform some settings and enter debug mode. They were of great help and very kind. It confirmed that 1 voice was not working properIy. And I almost sent it back for repair because the problem persisted. But meanwhile i tried to get the autotuning program to finish without errors. Again and again. And after a few days of not using it, i powered it up and the tuning finished correctly and the problem disappeared! :-)
So it looked like a software issue and not a hardware problem.
