I recently got a ducking compressor pedal for my rig. I had the idea to use the headphone jack on the BeatBuddy to control the pedal. The initial experiment proved very promising. Since I might want to focus on only ducking using the kicks, I thought that the ability to select which sound samples pass through the headphone jack could be very useful.
I don’t know if this suits your setup but you could make kick panned middle (both left and right) and everything else only left 
This way you could send right channel to ducking pedal and left would be mono out from BB to amp etc 
Just a workaround and if you want to have stereo out from BB then this doesn’t work 
Thank you for your input! I’ve forwarded it to the dev team.
