Apogee Control hardware. I have kept it unopened since I purchased it. I am selling it because I have no plans to use it. It is a new, unopened product. Below are the product details. Sometimes, controlling things from hardware feels the most natural. Of course, Apogee has been pioneering this approach, starting with the Duet. The 8 buttons and control knob on the Apogee Control can be assigned to various settings for control. It can also be easily connected to a Mac via a USB cable. - Hardware remote controller compatible with Apogee interfaces - Compatible with Symphony I/O Mk II Thunderbolt, Symphony Desktop, Duet 3, and BOOM - Simply connect to your Mac's USB port to remotely control the above audio interfaces - 8 freely assignable buttons - 1 assignable control knob - Multiple units can be controlled #apogee #daw #dtm
