Hi, today i bought a TM1, second hand, mint condition. A little bit less than half price for a new one. I wanted to update my SPS 1 UW MKII (1,53) Unfortunately it’s don’t work. I use C6 of course, the midi wires are plugged in to out and out to in. But nothing . Strange ! Maybe you can take a look on your os to tell if C6 works with 10.7.5 if its your OS ? Thanks a lot !
