I built my own HX Stomp MIDI Controller based in all your comments in this thread and it's working fine in the protoboard, I'm waiting for the case and momentary footswitches to built the defintive controller. Meanwhile I thought in add contros for the basic amp pots (drive, ch vol, mid, bass, treble) and I see thay I have to use encoders. I'm very newbie in the arduino world and I'm not programming anything since 20 years ago. I used today potentiometers and it works perfect controlling the amp parameters, the problem is that once you conect controller to the hx stomp, the potentiometers send their reads to the HX Stomp and modify all the parameters of your preset, so that's why I suppose encoders are needed. I've never used encoders but I suppose they are not hard to use. My question is, using encoders, is it possible not to modify the parametrer controlled by the enconder until it will be moved?, and, once you move the encoder, can I increase or decrease the value of the parameter near the value saved in the preset or automatically the value of the parameter will be changed depending on the value of the encoder?
