Hey, thanks for all the supportive suggestions. I am going to research the suggestions about additional devices. If there's one out there that is suitable, something simple (meaning not intrusive or hard to use live, non stop show, no fiddling ... zero fiddling, zero menus, etc.)
Here's what I've done so far, very similar to baekgaard's suggestion. (And thank you baekgaard for your response.)
The programs definitely eventually lose the 'one after the other behavior' of the clever Panel A, Panel B hack that was suggested when you start filling them with data. However, I kept around, luckily, two fluke programs, with nothing but the Panel A/B PC hack instructions in them. I can't even seem to recreate a simple program to do this very easily, but, I tried enough stuff that when I found one that sometimes switched to Preset 2 ... I kept it, and didn't EVER edit it after that, because that then breaks it.
So, I have a fluke program that (inconsistently) will switch to Preset 2. And I now have another fluke program that sometimes switches back to Preset 1 (it was a copy of the other, one that actually worked, occasionally.)
The way I overcame the 'occasionally' and 'sometimes' behavior, was to set up a preset 2 'song' in the song section like baekgaard suggested. I place it off alone, so I can roll back and forth past it a bunch to get it to trigger. But to make this ... easy? ... I've placed it a little farther away from any actual ordered songs in an empty area of the list, so it's ... alone. Then, I can spin the knob ... and twist back and forth aver it a few times. It almost always switches then ... within five seconds.
I know. Not optimal. But, it does do it. Then, songs absolutely requiring this bank, can be grouped close to that spot in the song list, to the right of that point, so to speak. I know, that is suddenly a big ordering limitation ... but, at least it can be done.
Then, I just recreated a similar area with the preset 1 program, and group certain songs around it's location in the song list.
I am going to keep experimenting at getting a stable program version of the A/B panel hack. My switch to preset 2 program, is more consistent than the switch to preset 1 copy of it. And it's very hard to even reproduce any program of the A/B hack that works ... but I fluked out and got two, and will now never delete them. They are already saved to computer and tucked away. But I'll keep trying to recreate an even more stable version, if I can.
So, that's the progress so far. I actually have several 'songs' in the preset switch area, all pointed to the preset 2 switching hack program for, say going to preset two. Then I am rolling over several instructions at a time when I roll over that spot in the list with the dial. Sometimes, hitting a program button here or there while rolling across the list with the dial also makes it switch faster sometimes. I've got a few 'song parts' that are pointing to the preset switch hack too. The point seems to be, trigger it a thirty times, and eventually it switches. I simulate that with the knob twists. Maybe a glissando over the song parts buttons.
My aim, is to figure out one clean Panel A/B hack to use, if I can ever get one. Because sometimes, it will switch the first time you scroll past it. And when it does, isn't that a treat! Then, I would just insert that in spots where I wanted to change banks in the song order.
So, like I said. Progress. And I will make even more progress. There isn't anything that can't be fixed with a little duct tape.
Thanks again everyone.
I keep feeling confident that I will hit upon the perfect combination one day, and be able to just place one 'song' in the list, over and over again where needed, that I can step past in the song list to switch it very seamlessly. But for now, I still have to roll back and forth over that spot in the list to get it to actually pick it up and switch the bank. But, it does do it.
I'm half way there. I'm determine to figure out something even smoother. And I will look into some of the suggested devices. For me, the key is ... I can't menu dive, I can't reach hard to pick out button on a hard to read screen, and ... I'm often emulating recordings that were multi tracked, and fronting a show, the lead singer. The whole point was one big large "next" button, a few inches from my fingers, on the same board. And all I even really need is PC changes, and volume control. Maybe, like ... one CC message.
Thanks for all the quick support here peeps. I'll get it figured. I'm getting closer. I'll bet this rig stays here with me. I'm 80% there already.
I'm interested in these midi re-coder boxes. But, I know nothing about them. Thanks for the heads up on that too. I'll check into it.
