Scale Workshop

Scale Workshop is a scale design application which can be used to design microtonal scales and play with them with a MIDI keyboard or an ordinary QWERTY keyboard. It was created by Sevish. Since version 2 the lead programmer is Lumi Pakkanen.

One common usage of Scale Workshop is sharing a link which represents a scale together with an isomorphic keyboard mapping, for example:

• https://sevish.com/scaleworkshop/index.htm?name=24edo%20semaphore&data=50.%0A100.%0A150.%0A200.%0A250.%0A300.%0A350.%0A400.%0A450.%0A500.%0A550.%0A600.%0A650.%0A700.%0A750.%0A800.%0A850.%0A900.%0A950.%0A1000.%0A1050.%0A1100.%0A1150.%0A1200.&&vert=-4&horiz=5

When you follow that link you can instantly play the scale using that mapping.

Another common usage is exporting your scales for import into synthesizers or VST plugins.

Trivia

Scale Workshop uses 5407372813edo to determine the constant structure property for just intonation scales. This is likely to be the largest number of equal divisions per octave which has ever been used for practical music making purposes.
