digital signal processing....

it's basically the speed, capacity, and capability of the electronics.

it's just a slower processor... it's limited when the current processor is working at capacity....

the new HD500x will also be limited... just a a higher capacity... which is more models... (it could have been higher quality models i suppose... higher quality requires higher processor capabilities too)

 

it's just like opening alot of programs on your computer... things get real slow...

the firmware on the pods do not allow things to get slow... because the quality would get bad...

You only get so much of it. I think of it like RAM in a computer. Some models (effects or amps) use more DSP than others.

When you're creating a patch, you may get a message that says something like, "DSP limit reached." Then you have to take something out to make room for the new effect or amp.

Here's a chart on which models take more DSP than others:

depends on your amp, and your reverb, and all those other choices...

i know you can put together an effects chain like that easy enough....

you may have to compromise here and there though.

Unfortunately, it doesn't work that way. It doesn't matter if you have an effect on or off at the time. If it has the potential to go over the DSP limit with all of the effects in your chain on, you won't be able to do it.

Sorry, I may have misunderstood what you were asking before.

 

Yes you can have you amp and 8 effects, but only as long as those 8 effects don't go over the DSP limit.

You can have your amp + UP TO 8 effects, depending on your amp and effect choices. You couldn't have 8 Spring Reverbs for example, as they use a lot of DSP. Most common combinations are fine though.

you can hit the dsp limit alot if you insist on using dual amps...

 

you can also avoid the dsp limit alot if you're fine using a single amp.

I can give you an example. I use one of the darker amps for distortion tone, and then one of the cleaner, brighter amps on top just a little for some added clarity that a presense not knob can't give you.

If you have two amps in a chain, you can set up a footswitch to switch between them if that's what you mean.

 

Otherwise, you can use footswitches 5-8 to select patches A through D in each patch bank (there are 16 banks of 4 patches for for each set-list)

so that works for no gaps in the change of presets?

Changing presets will result in a temporary audio gap. Switching amps within a patch will result in a slight pop/click sound if there is signal coming through. Neither scenario will give you a seamless switch.
