Scala Home Page Scala is a powerful software tool for experimentation with musical tunings, such as just intonation scales, equal and historical temperaments, microtonal and macrotonal scales, and non-Western scales. It supports scale creation, editing, comparison, analysis, storage, tuning of electronic instruments, and MIDI file generation and tuning conversion. All this is integrated into a single application with a wide variety of mathematical routines and scale creation methods. Scala is ideal for the exploration of tunings and becoming familiar with the concepts involved. In addition, a very large library of scales is freely available for Scala and can be used for analysis or music creation. Great care has been taken to make Scala's functions and operations very general. The range of parameter values that commands accept is made as general as possible. Often various forms of input are allowed. No arbitrary restrictions are made. Scales are stored in a flexible format. Intervals can be entered and saved as either ratios or cents values and be intermixed within a scale. Constructing scales from scratch is one of Scala's strengths. Kinds of scales that can be made with Scala include: equal temperaments, well-temperaments, Pythagorean (meantone) scales, Euler-Fokker genera, Fokker periodicity blocks, harmonic scales, Partch diamonds, Polychordal scales, Dwarf scales and Wilson Combination Product Sets. In addition, a Features Examples set of command files is included to build other kinds of scales such as triadic scales, circular mirrorings, circulating temperaments, etc., and to serve as examples.

It incorporates the command line interface of the old console version but also provides dialogs for almost all functions. The remaining functions can be used by typing Scala commands. Plays scale tones via the soundcard. Several screens allow different playing with tones of a scale via the soundcard's MIDI synthesizer or external MIDI instrument. Command line interface that recognises 800 commands for scale analysis and manipulation. They are case insensitive and most can be abbreviated. In addition, the command syntax includes powerful features similar to those of a programming language. Extensive on-line help. The built-in help function describes every command in detail and also includes useful information on other related topics. The help text is in HTML so you can view it with a browser and print it. In addition, the "tip of the day" function provides many useful hints and introduces features. Extensible functionality through command scripts. You can create a script file containing Scala commands with any text editor, and then execute it inside Scala. Can capture screen output to text files. Exporting scale data to other music software, such as Csound, is straightforward. A set of lexical functions is provided to convert program data to text. Exports tuning data to a variety of synthesizers with an internal tuning table. You can save tuning data in a MIDI file or send it directly to your instrument or sound card.

There's also a do-it-yourself hardware synth: PreenFM2 frequency modulation sound generator Other instruments can be supported through modification of an external data file, if the system exclusive data format is straightforward. Not all synthesizers have microtuning support in the form of a tuning table, or one with sufficient resolution, and therefore cannot be directly tuned by Scala. Hopefully more future synthesizers will be equipped with a full keyboard variable tuning capability. Be careful to check this before you buy. Flexible keyboard mapping. For scales containing more or less than 12 tones per octave, you can easily assign scale degrees to the standard piano keyboard by using a keyboard mapping. Scala supplies an example set of keyboard mappings for scales of various sizes that you can quickly adapt to your needs. Can retune existing MIDI files. You can convert a standard MIDI file to be in any tuning via pitch bend commands or a MIDI Tuning Standard tuning specification. Can relay real-time MIDI. You play on a MIDI keyboard to a soundcard or external MIDI instrument and have the tuning changed via pitch bend commands. This way you don't need an instrument with microtuning support in order to play in a given tuning. Can create MIDI files from a microtonal score. The score is a text file which can be created with an editor or generated from a MIDI file by Scala. The format is described in Scala sequence file format. The tuning is done either with pitch bend commands or MIDI Tuning Standard real-time single-note changes. Recognises more than 2200 musical modes. You can check any scale to see if it approximates an existing mode. More than 550 note naming systems built in. Notes can be named and shown in a consistent way with microtonal accidentals. Recognises more than 700 chords. You can check the occurrence of these chords in any scale. Recognises more than 450 rational intervals. Recognises more than 4000 regular temperaments. You can check the name by giving a generator and period. More than 4500 scales available. Download these for free from this website, see the Download page. Reliable.
