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 wide 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 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.
Several software synthesizers like AlsaModularSynth, Tobybear Helios, MAZ Sound VSampler,
Orion Pro, VirSyn Cube, Cantor, TERA 2, rgc:audio z3ta+, Cakewalk Dimension Pro and Rapture,
Oblivion VSTi and ZynAddSubFX have adopted the Scala scale file
format as a means to tune them instead of via a special tuning dump file. More will
hopefully be following.
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.
