Nord Lead 2 tuning problem

Has anybody else experienced a problem with master tuning of the Nord Lead 2 where the tuning "drifts" & must be retuned to other instruments? I emailed Clavia about this. They were not familiar with the problem but speculated that it might have to do with the pitch bend circuitry.

Sometime when sequencing it is possible that while editing bars that have used the pitch wheel, that you can cut off the pitch wheel's return to center which leave a synth frozen at the the last pitch wheel parameter it recieved, and the wheel needs to be recentered manually.

Check that it is not a particular sequence that always leave your synth out of tune. This may not be your problem, but it is an easy mistake to make.

I returned the Nord Lead 2 in December to Sweetwater Sound to fix the tuning problem under the warranty. They concluded that the problem was related to the pitch bend circuitry & replaced with new circuitry. It has been fine ever since.
