Hello,
If you press the Mixer button to the right of the display and then the Part button located below the left side of the display, you will have access to all of the accompaniment track volumes. Make the desired changes to a style and then press the Store button located at the far right of the Resources section of buttons below the display. Here you can choose to save Style Presets among other options. If you choose to save the edited Style to the first Style Preset, then anytime you call up that style, your edits will automatically be loaded.
Best Regards,
Dave
