This is by far the most essential music app I own now, a perfect companion for any DAW! Brilliant tool for songwriting and workflow, enabling me to compose in a fraction of the time and get the ideas out to my students or band mates with very presentable lead sheets. Tonaly is a must have, offering a wonderful array of tools for both creating and practicing scales, modes, chords, harmony and other theory. Well done!

The Real Deal

Anyone who has an interest in songwriting or musical theory will find this app worth every penny. It becomes even more powerful when using the MIDI out to Logic Pro on the Mac. Highly recommended for songwriters and music producers in general.
