This app allows you to break out of the limitations of equal-tempered scales and gives you freedom to tune the built-in keyboard in whatever way you want. Loaded with many presets and samples you can explore ancient scales, byzantine music, oriental vibes or configure your own scales. Have you ever wondered why we tune our instruments the way we do? They are usually tuned to an "equal-tempered scale", which divides the octave into equally spaced tones and semitones. This has become the most prevalent way of tuning the instruments in the west since the 18th Century. Today, musicians use this tuning system, and the scales based on it, without ever considering other ways. For example, in the Middle Ages European musicians generally used Pythagorean tuning, and today many traditional instruments in the Middle East and Asia are tuned according to regional systems and standards. Included features: ● Ability to tune each key in the octave individually (+- 100 cents). ● 35> High quality sampled instruments: From grand piano, violin and organ to oriental oud and kanun, to voices of a choir singing Ison voices. Many samples are polyphonic and have multiple velocity layers. ● MIDI In. Connect your External MIDI keyboard and play microtonal music. Tuning the individual keys is normally only possible on $1000+ keyboard! ● Many presets introducing lesser known western, byzantine and oriental scales. ● Ability to save your own scales and tunings. ● Entering directly frequency ratios, frequencies or cents. ● Shows on the piano keys where the scale starts and what keys are included in the scale. ● Changing the root key of a scale: all tuned keys are shifted correctly. ● Audio effects: reverb and compressor. ● And more… ## WorldScales Screenshots -
