Completely switching pedalboards requires to disconnect and remove one jack client for each effect, then add the new ones, connect them and load their default presets.
If all you need, as an example, is to lower the reverb and add some gain and overdrive during a solo you would like to quickly modify the parameters of those effects at once.
A typical live situation would be:
At the beginning of a song load the relevant pedalboard
During the execution you can change the presets of some effects, running through a predetermined list
At the end load the pedalboard relevant to the next song
It is the workflow that I have seen on the other effects/amp simulator I know, like guitarix or rakarrack
Yes I understand now. Obviously the transmission of concomitant midi cc values would help you out with this. I cant comment as i havent attempted that yet but check this tread a device mentioned might help with your needs. Swe below
But in realtion to first query i have know idea why this function was left out but Mapping the button to presets would be a nice feature
