I understand that. What is confusing is the behavior of engaging that one specific effect in the midst of all the others in the preset. If ONLY that effect is engaged it shuts off the reverb to conserve CPU. If ALL other effects are engaged simultaneously there isn't a CPU overage. That's why I'm suggesting it's a bug.
Forgive me if I'm missing something, but that behavior doesn't seem consistent.
Jeff, I have the same problem which I've reported to FAS. The issue is....you and me just don't quite understand how it's possible to have a preset totally working while the blocks are in place, yet step on something and something auto-disables.
In my particular situation, I converted an XL+ preset to an AX8 preset. There were things in the AX8 that needed to be altered. The compression change to pedal 2 helped immensely and the big one was "economy" in my pitch block, which we don't have in the XL+. So I never thought to check there.
That said, I STILL couldn't get the patch to work without removing something. (multi-delay that I use for Steve Stevens ray gun sound) That's just the limitation of the AX8 for certain situations. My personal stance on this would be, if the blocks are allowed to load in the preset, nothing in that preset should disable anything. If the preset simply can't handle the blocks, I would rather know that from the start of the preset creation.
For the most part, my AX8 has been able to handle all my presets other than the one with the multi-delay and one of my fully loaded Van Halen patches. The fix is to recreate the patch with something that ISN'T turned on in that algorithm and you just hit that preset when you need it. You have to hope you don't get a glitch (which is why I use scenes) but that's the only way really.
When you can't load up something the way you want either because of memory issues, you just recreate without stuff that may not be needed. For example, in my patch that failed, I don't always use the pitch block, the delay block or the chorus block. So all I have to do is recreate the patch on a new preset that doesn't have those effects and I should be golden...which is what I did. The downside for me, spillover on doesn't stop the little lag I get when changing to that preset.
I wish I could use it in a scene so I can just off/on that multi delay block like I can in the XL+. But....that's just the way it goes man. That's why the XL+ costs what it costs. BUT...that little AX8 is a mean bitch that should get you close to anything you want with a little tweaking and scaling down. My biggest pet peeve is not being able to use the studio compressor at times because I always seem to be like 2-3% off. LOL! I think it obliterates anything else we have in those options as far as compression goes and hope one day we may see a reduction in what that uses compared to the others. Then again....same thing...the better stuff, uses more resources so we just have to keep playing around until we can find that happy medium. Or, get an XL+ and never run out of anything other than money! LOL!
