Hello, I have a question. When I plug ditto looper into loop effects and set chanel A as a clean sound (I preset) and chanel B as a hi gain (IV preset) and record some clean melody on chanel A, and then switch to chanell B then characteristic of this clean melody change a bit (its still clean but more bassy and not as good as it was recoded on looper) , as I can observe characteristic of this sound recorded on chanel A changed depends on what preset is set on chanel B. Is it possible to sound exactly as it was recorded on chanel A (I preset) and not changing any characteristic? Second question, I heard that there is possibility to uprade some soft in DT25? How to do it?
