it seems there are some other folks in this thread reporting the same.

We would like you to do a simple test:

-load the factory Undulator preset and play. DO NOT CHANGE ANY PARAMETER! Don't touch any knob.

-if it's working fine, procedd to ONLY change the lfo shape to SINE. Don't tuch any other knob. Does it work?

-Please describe how the MF is connected to your gear with the following details:

-type of cables

-connection to guitar or fx loop?

-if it's inside an FX loop, what's the signal impedance (+4dB/-10dB)?

Thanks

best
