This setup has the repeated riffs on low E and F keys, and a little arp up high. The middle is to play the other string lines. Kick drum turn on/off on low F# and G#.
One of my 1st attempts with riffs. please give feedback.

Can you tell me why when I use your setup the VOLUME of the next setup is very lower than the original?

...if I press PANIC the volume set to OK.

It doesn't do that here, but I can offer this:.
Each zone"s volume is controlled by a slider. Each slider SHOULD be programmed with a ENTER and EXIT level, so that when you change sounds each midi channels' volume resets -- except I didn't do it. It has never been a problem for me. Still when i change from that sound to another, the 2nd one sounds fine. I'm sure someone else reading this will jump in with a solution.

Do you create setups and assign "none" to the entry volume on the PANVOL page?

Yes, I usually do it like this.
