This is a windows and Mac program designed to allow you to control MIDI devices using the computer keyboard and only the computer keyboard. The advanced version gives you virtual pitch benders, realtime properties, controllers, pan/volume/reverb/chorus control, and much more!

The free version is limited and is only designed to allow you to get a feel for how the program works, and allows for basic playing. Please consider the advanced/paid version to unlock more advanced controls and customization!

On Mac OS, no setup is required. The app automatically shows up as a MIDI input device, and most apps will pick up on it. If it doesn't, consult your app's documentation on MIDI input device setup. In addition, the mac's demo is different than the Windows version's demo in that you can use the app for 2 hours of full usage, at which point your trial will end and you are forced to register. CMK for Windows keys are valid for CMK for Mac. The two hour trial only counts while the program is running.
