Is it possible to implement a led in MBSeq V4 to show the midi in activity?
ucapps.de -> core32 there is some info..
You could alsbo split the signal from the midi input (google “midi thru schem”) and put a LED on one of the outputs. With a 74HC14 you get 6 inverters and you need 3 per LED (invert -> 2x uninvert => led + midi in/out) so you could do MIDI In and Out with just one IC. Just a thought
