Midi cc number can only be lower than the number 10，How to set a cc number of more than 10 on the device(not pc software)? Like 99、125?
What device are you talking about?
All Morningstar devices allow you to set CC targets and values across the full range 0-127.
Please try editing midi cc directly on mc6 pro device
Regarding editing directly on the device, you’ll need to press left and right (Switch B & C) to scroll through each digit. It does not scroll from 0-127. But rather, you can scroll through each of the 3 digits and set each digit to get the number you want.
