=Description= 
//Scala// is a freeware software application with versions supporting Windows, Mac OS X, and Linux. It allows users to create and archive [[scale (music)|musical scales]], analyze and transform them with built-in theoretical tools, play them with an on-screen keyboard or from an external [[MIDI]] keyboard, and export them to hardware and software synthesizers.

Scala can retune MIDI streams and files using pitch bend. It also supports MIDI sysex and file-based tunings. Originally a command-line program, Scala now uses the [[Gtk+]] GUI toolkit. Scala is written in the [[Ada programming language]], and is the work of Manuel Op de Coul of the [[Netherlands]].

Scala can also be used as a midi sequencer, by way of its [[ASCII]]-based sequencing format, ''seq''. Because of its great flexibility when it comes to tuning formats, it is a very powerful tool for those who want to compose and sequence [[microtonal music]].

Scala's motto is "Invenit et perficit", Latin for "It finds and perfects" or "It discovers and accomplishes" in [[Latin]]. Its logo is a [[Renaissance]]-style [[relief print]] of a [[cherub]] holding a [[compass (drafting)|compass]] and a globe inscribed with a diatonic musical scale and a [[circle of fifths|circle of fourths]].

=File formats= 
Scala can open, transform, and save standard MIDI files. It can also export MIDI tuning tables in .tun format. It provides a native, human-readable sequencing language (.seq). But it is best known for its use of human-readable text files to store musical scales.

The [[http://www.huygens-fokker.org/scala/scl_format.html|Scala scale file format]] has become a standard for representing microtonal scales in a way that can be used by other software. The Scala site lists over thirty applications that support the format, including several major commercial packages like [[Apple Logic| Apple Logic 7]], [[Melodyne|Celemony Melodyne 3]], and [[Cakewalk (company)|Cakewalk]] Rapture<ref>[[http://www.cakewalk.com/support/rapture/rapturetuning.asp|Rapture Microtuning and Alternative Tunings]]</ref> and Z3TA+<ref>http://cakewalk.com/Products/Z3TA/Z3TA+%20Waveshaping%20Synthesizer.zip</ref> . Scala's developer also makes freely available an archive of over 3,500 Scala scale files, containing many musical scales of historical, cultural, and theoretical interest.
