This feature was requested on the Windows version FIVE YEARS AGO! Every other Windows program uses the space bar to start and stop media playback, but Make Music still forces one to use the mouse. This is not only inconvenient, it's annoying when, out of habit, one keeps hitting the space bar to no avail. And no, Space Bar Click is not the same thing as starting and stopping playback like the Play button.
Come on Make Music. Get with the rest of the world please!
