Music Composer for the Commodore 64 lets people with little or no musical ability or computer skills arrange and play electronic music using three separate voices and nine musical "instruments." Simulated instrument sounds include an accordion, calliope, rhythm sound, flute, harpsichord, organ, harmonica, xylophone and banjo. Use your computer keyboard as a piano to compose and arrange songs, then save them to tape using Commodore's Datasette peripheral.
To jazz up your melodies, a number of special effects are provided including vibrato, pulse width modulation, ring modulation, sync modulation, dynamic filter effects, attack/decay, sustain/release and waveform. The four waveforms (white noise, pulse, sawtooth and triangular) determine the tonal quality of the sound produced by the instruments. You can also incorporate filtering that allows you to choose which harmonic frequencies will be heard.
