Tell us about MusicN and if there are any composers out there today who use this software. — Preceding unsigned comment added by (talk) 14:57, 15 July 2005

Merge from Music4[edit]

I think it would make sense to merge the content of Music4 on this page.Bikepunk2 (talk) 16:23, 23 November 2010 (UTC)

I agree that Music4 should be merged to here (and corrected to MUSIC IV as is used in sources.) --mikeu talk 20:52, 19 March 2011 (UTC)

Cut and paste merged. Hyacinth (talk) 10:00, 12 September 2012 (UTC)

CSIRAC didn´t make digital music[edit]

As stated in the first paragraph... Why not? I´m guessing it´s because the Csirac didn´t have a DAC, just a "debugging speaker"... the IBM 704 manual doesn´t mention any DAC either, nor debugging speaker, so how did MUSIC I make sounds?

first post on wikipedia... will thank help if I made any mistakes Histriocito (talk) 01:34, 2 December 2010 (UTC)

Do you mean that the reference from the University of Melbourne ( ) is pure fantasy ?

I guess they somehow adapted an external DAC on the CSIRAC. Bikepunk2 (talk) 17:10, 2 December 2010 (UTC)

I don't know about CSIRAC but at Bell Labs Mathews describes a process where an IBM 704 or 7090 writes a "sequence of numbers recorded on the [digital magnetic] tape" which is then placed in a standalone DAC. The DAC converts the tape to a "sequence of pulses proportional to the numbers from the digital tape." This is then run through a low pass filter to produce a "smooth time function" output to a speaker. It is clear that the DAC was not a peripheral attached to the IBM at this date. He also says that it takes 4 to 10 seconds of computer time to generate each second of music. Mathews, Max V. (May 1961). "An acoustic compiler for music and psychological stimuli". The Bell System Technical Journal. Bell Labs. 40 (3): 677–694. doi:10.1002/j.1538-7305.1961.tb03237.x. Retrieved 24 January 2016.  --mikeu talk 14:13, 24 January 2016 (UTC)


I've tried to clean this up a bit and at least add one reliable source for the early versions. There's a complete family tree of N at Music N. (Though annoyingly they use lower case for "MUSIC N" despite the fact that early computers were only capable of uppercase letters.)[1] --mikeu talk 07:30, 24 January 2016 (UTC)

Clarification: the all caps for MUSIC above refers to the Bell Labs versions. The manual for MUSIC 360 mentions "MUSIC 4B" instead of MUSIC IV.[2] --mikeu talk 07:44, 24 January 2016 (UTC)

Early computer programs like MUSIC and FORTRAN (both of which ran on the IBM 704 which had a limited character set that did not include lowercase letters) originally had names that were all uppercase. When these program were ported to a newer computer that did support lowercase there was not always a consistency in the naming convention. For example, MUSIC 360 on the IBM System/360 which had lowercase as part of the EBCDIC character set. During this transition original sources sometimes refer to MUSIC IV or Music IV. (There are also variants such as MUSIC 4 or Music 4.) I'll try to track down what the original authors called the programs that they created. I propose that the article adopt a convention of using all caps for earlier versions where this was the case and lowercase for later versions, despite the fact that some recent references often use historically incorrect usage. A section similar to the following should be placed near the top explaining how the early sources rendered the name, how the name is found in a variety of forms, and the convention adopted in the article. --mikeu talk 12:44, 24 January 2016 (UTC)

"Because the capitalization usage was sometimes inconsistent, this article adopts the convention of using the all-caps FORTRAN in referring to versions of the language up to FORTRAN 77 and the title-caps Fortran in referring to versions of the language from Fortran 90 onward. This convention is reflected in the capitalization of FORTRAN in the American National Standards Institute (ANSI) X3.9-1966 (FORTRAN 66) and ANSI X3.9-1978 (FORTRAN 77) standards and the title caps Fortran in the ANSI X3.198-1992 (Fortran 90), ISO/IEC 1539-1:1997 (Fortran 95) and ISO/IEC 1539-1:2004 (Fortran 2003) standards."[3]
