Charles Callet was a French composer and sound programmer.
In 1976, he composed the song Le matin sur la rivière for the singer Ève Brenner, which reached number one in many countries, excluding France. Later, he worked as a music engraver and in surveys. Under the pseudonym Loudvig, he sung the song Radio Sex Appeal for the young radio station NRJ.
In 1985, he bought himself an Amstrad CPC 464. Not able to find affordable scorewriter software, he wrote Amstradeus in BASIC in six months.
In January 1986, he founded his own company, Music Logiciel. Six months later, he started working with Infogrames and wrote a music editor called Music Pro in assembly language. He also worked with Ubi Soft, Lankhor and Microïds.
Besides computer music, he composed 300 variety musics, 2 lyric works and 8 symphonic works.
By 1990, Callet had made an Amiga version of Music Pro.
Callet composed using his own editor, Music Pro. The editor was published, but in 1990, he said it was a commercial failure.
Callet composed using Music Pro on the Amstrad CPC, and transferred the compiled music files to the ST, for which a driver existed. In 1988, he announced a ST version of the editor.
Callet mainly composed using Music Pro on the Amstrad CPC, and transferred the compiled music files to the C64, for which a driver existed. In 1988, he thought there was no market for the editor on the C64. He acknowledged the better quality of the SID, but criticized the lack of independent volume registers and the irregular processing time taken by the video chip.
In 1988, Callet announced a PC version of Music Pro that would support an extension card with two additional voices.
