what is your firmware/fpga versions?

My one:

There is ambiguity for MOD input specification. The manual claims that it has 0...3 V range. But it is used for VCO mode and the same manual claims that VCO voltage range is 0V-5V. So, it's not clear what is voltage range for MOD input.

I tried to test it with 0-5 V and according to ADC values, it looks that MOD input range is 0-5V, but it can see difference even for 5.2 V and above, with non linear code.

I have just noticed on mine that channel 1 output becomes VERY noisy when i turn on modulation. May have to send it back
