I bought a new OB-6 key version two weeks ago and it's always way out of tune upon startup. I realize VCO synths need some warmup time, except the OB-6 (like the P6) has an internal temperature sensor and the data is stored in a table every time it's calibrated. I currently own a P6 key version, which hasn't needed a single calibration and had an OB-6 module, which needed slight calibrations on very rare occasions & only randomly while playing. I contact Sequential support about this and was told it's normal and would cease after a while, except I just don't see any improvement and doubt it's going to get any better.
Does/did anyone else experience this? If it got better, how long did it take to improve?
Edit: Just to be clear, it does stay in tune once calibrated, yet it's back to square one with being out-of-whack every time it's turned back on if it's had a sufficient amount of time to internally cool down again.
