I have two Plaits and with both the Timbre changes slightly within 15 to 30 seconds without any CV applied.
The Attenuverters are in the middle position. I tried putting them a bit to the left and right, but that didn’t change anything.
Could this be connected to the internal decay envelopes?
Or maybe it’s the Morph parameter? The sound gets ever so slightly thinner and then goes back to a more full sound.
As far as I can tell this only happens in the first green mode (pair of classic waveforms).
Sorry if this has been answered before. I searched, but couldn’t find an appropriate previous thread.
