I've loaded in about 25 styles and 12 standard midi files and they all play great.
Also, I've plugged in a roland pedal and selected the setting "Rotary" and it adjusts from slow to fast rotor if the organ sounds are assigned to "rotary" with the MFX effect.
What I still want to find out is if I can change (edit) the volume of tracks within a song (I can within a style) and I would like to know if I can change sounds within the style and song. I haven't been able to find this out yet.
I did find that I can transpose the whole keyboard, including song, or just the song or just the keyboard. This is usually a feature found on more expensive arrangers.
