Inverse Side Chain for Gate

[simonp54]

Is it possible to invert the side chain on the Gate block?

I play piano and guitar and both will be going through the AFX3. I'd like to be able to mute (or at least lower the level of) the guitar whilst playing the piano and an inverted sidechain feed to the gate would work a treat.

Any ideas?

You could try a compressor for that.

If you want a fixed attenuation amount when piano level exceeds some value, another option with piano as gate sidechain: Invert the guitar signal before or after the gate, and sum this with the original non-inverted signal. Lower gate output level to get less attenuation.
