When I’m using external reverb/delay I like to have a tail when I turn of the fx. (same with internal effects) By turning down wet/dry knob the volume of the effect will go down but when I push the BPM FX (on/off) the effect sound is directly off/on , no tail. This is because the return level is cut but I would like to see that the insert level is cut. So when you push the BPM FX (on/off) you still have a tail and with the wet/dry knob you can level the return volume. I would really like to see this option available in a next firmware.
