Yes I know, in fact I tried my best to connect an external drum machine / groovebox to the Prime GO (as you can see here: Show your home DJ booth (Part 1) - #399 by ElTitoFranki), but I had to solder wires, all the cable connections are quite messy and all the process is tedious to say the least. My solution is “functional”, but it is not so fun to use as if there was an easy way to directly connect an external gear to the Prime GO.
