I think it is not that difficult. It is for sure necessary to provide the hottest signal to FOH during soundcheck. Therefore apply the 2-3 dB at the beginning. Afterwards as amateur band you have to make volume decisions considering soloing on your own as there is no chance the FOH guy is capable of adjusting volume for your lead stuff as he doesn’t know where to start or end … and sometimes little dBs are necessary.
And even currently you are not able to choose routing for separate stomps. It comes out as loud as a booster is dialed in and effects all outputs equally … no decisions can be made apart from Kone Cabs @ monitor out.
Simple problem simple solution … a master gain boost predetermined value.
P.S. With a wireless system you r able to listen to the pa. I am mostly playing small venues …
P.S. And yes new features always makes people wanting more but should have Kemper stopped developing Liquid Profiles only because people want more features afterwards? This amazing toy can be pushed further for sure …
