Using Expression Pedal for Audio Mixer

Hardware
1

I have an USB Expression Pedal which can be used as MIDI In (Arduion Leonardo).
So i can controll the volume of my HanonB70 instrument.

If decrease the volume as far as possible i can still have an output to my audio mixer.
Seems that the Volume slider of the B70 set to 0 still gives a little output
Of course i can decrease the outgoing signal in the below audio mixer but wouldn’t it be better to control the volume of the audio mixer and not the instrument?

if i use this on stage i will overlay the HanonB70 over my Pianosound, but only if i use the pedal.
So the “noVolume” status of the pedal should give an 100% piano output without any rest of B70

I would define the max volume with the instrument and then control the volume of the audio mixer of this channel.

Is there any possibility to control the volume of an audio mixer with an USB/MIDI expression pedal?

Thanks for any Idea

Are you aware of how to MIDI map widgets?

Oh sorry, of course you are right. I mapped the pedal direct to the volume slider of the ausio channel and this works fine. thanks for the hint :wink:
