I don't know if you're going to have any luck with the Yamaha USB driver in Sierra.Yamaha hereby grants you the right to use the programs and data files composing the software accompanying this Agreement, and any programs and files for upgrading such software that may be distributed to you in the future with terms and conditions attached (collectively, “SOFTWARE”), only on a computer, musical instrument or equipment item that you yourself own or manage. If you are having trouble with a control surface in Logic Pro, then delete the .cs file from the preferences folder. See the Logic Pro User Manual for details on how to do this. You may wish to export your custom key command as a preset before performing this step. Note that if you have programmed any custom key commands, this will reset them to the defaults. Remove the file from the Preferences folder. (exactly as you see it) ~/Library/Preferences Type ~/Library/Preferences in the "Go to the folder" field. In the Finder, choose Go > Go to Folder from the menu. You only need to delete the Control Surface (.cs) file. Here's the instructions to delete Logic's Preferences and Control Surface file. Make sure the sustain pedal is plugged into the keyboard then plug the Yamaha's USB connector back into the same USB port. With the computer on, unplug the Keyboard's USB connection and the Mac's USB port. Sounds like a controller issue, like Logic has picked up your keyboard and mis-assigned a controller profile.īefore following the steps below, try this.
