I’ve resumed my path towards the ultimate DIY midi controller, although the casing (and old marshall footswitch) is filling up(?) with holes 😉
Latest addition is a display of the current bank & patch number, although I’ve belatedly realised it’s not much use knowing which pedal I last pressed, so the display is now down to a single digit. Crazily, the single digit device I bought requires 8 pins of the arduino, whereas the 4 digit device only needs 4 (it has a multiplexer built in). I’ve even managed to teach it to display “arse” – MOST useful 😉
