1. patch level. how loud each sound is. it can make patch e.g. A1 be louder or quieter than the other patches. (a patch is the sounds you flic between.)
2. changes the patch to include compression or a limiter or a wah.
3.changes the frequencies that each patch gives out (you can make it more bassy/trebly what ever.
an the others i cant remeber. but just play around with it a you'll get the hang of it anyway.
by the way if you edit a patch then move off it without saving it it will revert back to how it was.
The sun is shining the weather is sweet
