If the CC121 has been forgotten about, that is a real shame. I’ve had mine for about 2 months and now am completely dependent on it. Its sped up both my tracking and my mixing. I think a reverse feature for the button LEDs would be great, i.e. that they would be lit until in use. With the new controllers, I doubt they will come out with a new hardware version, but an updated driver, with the suggestions in this forum topic, would be great. Next purchase for me is the MR816 CSX.
