I went through and transcribed a lot of keys and scales and saved them as presets into Cthulhu.
The list of scales is as follows in every key, C all the way up trough Bb.
The chords of each scale/key are ordered in Cthulu as follows:
With the exception, of course, of the Whole Tone scales, which only has the Triads.
Instructions for how to add them to the preset menu are in the ReadMe that comes with the zip file.
Hope this is the kind of thing you guys were looking for! Fee free to e-mail me with any questions.
