General MIDI Instrument Library

The General MIDI Instrument Library defines the sound of 128 melodic instruments and 47 percussion instruments. Here is a small sampling of sounds from the GM library. These were generated by converting a MIDIFile to a WAV file using the ME1000 Ringtone Engine, then converting the WAV file to an MP3.

Listen to Some Individual Instruments from the ME1000
#11 Vibraphone	Uses FM to generate enharmonic partials.
#18 Rock Organ	Saw and Square waves with vibrato.
#23 Accordian	Modulated square waves for intense sound. (Pitch dropped at end of song to simulate deflation.)
#74 Recorder	Use noise to model breath sound.
#97 FX2 Soundtrack	Two pole resonant filter for space sound.
#114 Steel Drums	Uses FM to generate enharmonic partials.
#124 Telephone	Uses envelope loop to generate rapidly repeated ring.
#125 Helicopter	Filtered white noise to model rotor noise.
