Buy yourself a copy of
StyleMagic... you will glad you did. You can change the octave in just a couple of seconds and do a whole more editing with the program.
StyleMagic is copy protected. The author requires you have a USB
thumb drive (and no other USB drives) plugged into your computer when you buy the program. The USB drive will serve as a dongle to allow the program to boot. The program is portable so you can run it from any computer that has the dongle plugged in.
StyleMagic has excellent Voice and Drum Editors, and enormous editing and mixing capabilities. You can download a demo version of the program to try before you buy. The demo is fully functional except for SAVE. Features include full support for all Yamaha arranger keyboard models, Export and Import of individual style Parts and complete style Sections and has the ability to create styles from MIDI song files as well as importing style Parts and style Sections you have saved to disk.
A trick I learned early on is if you change the file extension of Multi Pads from .pad to .mid you can load the MP into StyleMagic and convert the MP to 4 Parts of a style. You will have to move the MP channels from ch 1-4 to the appropriate style channels 9-16. BTW... you will have access to the alternate channels 1 - 8. And if you edit or Export a style Part that uses and alternate channel for Minor or 7th chords those channels will be edited also and Exported along with the main channel (9 through 16) The program also supports expansion packs. There is a free utility to add expansion pack Voices to the program. I have added 5 expansion packs to my copy of StyleMagic.
