As a result, General MIDI 2 (GM2) was introduced which implemented these changes, but maintained backward compatibility with the original GM standard. Of course in practice, manufacturers want their products to sound good when playing back MIDI Files, and so this is rarely a problem.Īlthough the GM specification enabled industry-wide compatibility, some manufacturers felt that further features needed to be added in order to keep up with technological advances, such as the addition of onboard effects processing to provide reverb, delay and chorus. Note however that General MIDI only defines the names of the patches - how each one actually sounds is down to the manufacturers of each different instrument. The advantage of this is that a pre-programmed MIDI File containing the instructions for a piece of music will also be able to choose all the correct instruments in the arrangement. To enable a number of unpitched percussion sounds to be played simultaneously, the specification also lays down specific individual notes that these are assigned to, rather than separate patches, so the kick drum is always on the same note, the snare on another and so on. The GM specification also details that MIDI Channel 10 should be reserved for unpitched percussion sounds, and the rest for pitched sounds arranged into 16 families of instruments.
