Each Free “Test-Drive” Demo includes all Modes and 30 types of Chords, but for only 2 Keys (D & E), 2 Scales (Major & Hungarian Minor), and limited Guitar/Bass Tunings – so you can “kick the tires” a bit.

The “Member” Versions include all Modes and 30 types of Chords for all 12 Keys of 20 different Scales, and every possible Guitar/Bass Tuning, plus the ability to Add a Note to a Scale (for expanded Melodies, and additional Chords), and more.
