A friend built my Ksoloti Gills for me and he’s about to calibrate the CV channels.

What should the CV Output be? -5V+5V or 0-10V. Or can this be changed later if i want to using the software?

My sequencer is a KORG SQ-64.

Hi, it should be calibrated to +/-5V as described in the help patch below.  
[https://ksoloti.github.io/6-1-gills\_build\_guide.html#cv\_calibration](https://ksoloti.github.io/6-1-gills_build_guide.html#cv_calibration)

Both channels are +/-5V by default but there are small solder jumpers on the CV expander board which let you set either to 0-10V (will need to recalibrate). It is not possible to change this via the software.
