Well, assuming you’re NOT using a “no keyboard” firmware and your MC is connected to your PC/Mac via USB, a keystroke message should just work. Search the manual for “keystroke”: MC6 MKII User Manual (that’s the MC6 MkII manual, same for all devices). A gotcha causing it not to work might be this? Certain Functions Are Not Working
Hi. There’s no need to use MIDI Learn on Ableton if you are sending keystroke commands from your MC6 PRO. As long as the correct keystroke messages are being sent, it will work automatically. We explain and demonstrate this here:
Well the USB connection issue isn’t going to help for sure… I guess you’ve rebooted the windows box and power cycled the MC?
Are you connecting the MC directly to a laptop USB port or via some sort of USB hub? A direct cable between MC and laptop is normally best.
Assuming you get a stable connection, try changing the Right Arrow to e.g. the letter Q, save the preset and click the Disconnect button in the Editor but leave the MC and Laptop plugged together via USB. Then open Notepad and press the MC’s switch… do you see the letter Q?
It might help if you try (on Windows) removing the MC6 PRO device in the device manager. There should be one under Keyboard though it’ll likely be just a generic name, then disconnect and connect the MC6 again to reinstall the driver.
