Do you have any modules in that case that may be sending signals on the internal CV bus An A-190 for instance Of course that should effect both VCOs unless one has the jumper set to look at the CV bus, and the other one doesn't.

Hi, I have two A-110 VCO's mounted in separate mini cases, and with their CV input fed from an A-182 switched multiple. generally I have them tuned to unison, but 1 octave apart.  The 'tune' knob is set to 5 in each case.

Every once in a while when I switch them on, one of them has an offset of  a 5th interval against the other, and I have to retune it using the P6 Offset pot. Note that the 'tune' dial is showing the same value as before 5th note offset developed.

This has happened to both of my A-110 VCOs at different times.  They were purchased from separate suppliers several months apart, so I do not believe they were from the same batch.

At the moment this is just a nuisance, however if it continued I would start to worry that other faults are going to develop.  Has anyone else experienced this 'phantom' 5th offset, and if so, what did they do about it

Hoping you can help,

Thanks, Blair
