Hi there I have an issue with my a4 mk1.
I noticed a strange resonance peak when playing chords. The 3rd voice in each chord would sound as though res was at maximum and also not obeying the any filter envelop settings. I have run multiple calibrations and consistently fail with a filter 33 code.
It seems to be the multi mode filter that’s the issue on voice 3. Is it dead? Any help would be appreciated greatly.
I’m on the latest firmware, but have tried calibration on this os and earlier ones to the same result.
