I planning on using a graphical at the end, and 2 (or probably one initialy due to the costs) 2x40 LCD's on each core so you can see what you are doing on each channel. So you can use 1 encoder to select function (balance,AUX,bass,treble, etc) And one to select the value. I would then have something like this: [table][tr][td]PAN 1[/td][td]BASS2[/td][td]AUX3[/td][td]TREB4[/td][/tr] [tr][td]L35[/td][td]+5db[/td][td]-20db[/td][td]+2.5db[/td][/tr][/table] Greetz tHe_IkkE P.S.: I forgot to put an LED-digit MTC display on the right
