An easy solution is to buy a copy of StyleMagic (it's supports the Genos). You will be glad you did. Editing a style is soooo easy with the Voice Editor and Drum Editor. And you will have access to the Alternate channels 1 - 8. In the Mixing Console you can change Octave, adjust Volume, Pan, Reverb, Chorus, DSP1 and Insert DSPs on any style Part in seconds. Even adjust over-all Volume for all Parts. In the multieditor (Piano Roll) you can do a whole bunch of editing and quantizing, add Filter and Pan Sweeps, Sidechain effect, etc. Then there is the CASM Editor, Channels Manager (swap Parts around) and Section Manager (lets swap Sections around, and save/load an entire Section to/from disk).
And rumor has it that there will be a powerful new feature on the next StyleMagic update (which is always FREE).
