Proxy CPU issues in this scenario?

[boynigel]

Long time LT user here who’s been holding out on Stadium, but now I’m feeling a bit more incentivized to possibly purchase one w/the recent release of Proxy.  Question regarding Proxy’d amps and possible CPU limitations:

 

Let’s say I want to clone all three of my amp’s channels.  Correct me if I’m wrong but it seems that I’d have to store each cloned channel as its own block within a given preset, which is where my concern lies in terms of running out of CPU...and i'd need them all in one preset to call up via snapshots.  That said, i'd just be cloning the amp head, no speakers, so that might save me a little bit of CPU, but still, 3 Proxy's in 1 preset, along with other effects blocks seems it would be munching up CPU quickly.

 

Warranted concern or is there a workaround to this.

I dont think it saves CPU when cloning without cab, as you will need one afterwards ;)

Not sure, though.

 

 

Regarding your understanding of  amp channels: yes, each channel will be its own clone. 

I did not try myself, but I saw people on YouTube using three clones in own preset, utilizing both CPUs (you just can do this by guiding path one out to path 2 in).

Two proxies/path seem to work.

You’re not wrong; that’s a warranted concern. Early anecdotal measurements suggest that an amp clone uses roughly the same amount of DSP as an Agoura amp model. So pending further detailed specs it’s fair to consider them equals. So the question becomes: can you create a preset now using Agoura amp models that does what you want? If so you’ll likely be able to simply substitute the clones when you have them. If not you’re likely to run into a similar DSP constraint.

 

Another relevant point: some have wondered whether you can swap clones in and out in a preset using Snapshots. Specifically, would you be able to use your 3 clones in a single Clone block in the preset? The answer is no for the same reason that you can’t do that with amp or FX blocks. Each clone, like amps or FX, has its own DSP requirements that need to be calculated during preset construction. For instance, you can’t put a generic Reverb block in a preset and change reverb models using Snapshots.

i don't know, as i haven't taken the Stadium plunge yet.  i'm sure 3 clones of each channel can be done in a single preset as another person mentioned, but i'm guessing there's little room left CPU-wise for any moderate to heavy effects processing...especially if i'm to use pitch-based effects, which i do use.  probably isn't going to work for me.

You can use 3 clone blocks in one preset and switch between them using snapshots.

correct, but you'd be on the brink of running out of CPU...at least i would as i use poly pitch and other CPU hogs.

Yes, unfortunately, there is an end somewhere.

..but tbh... I personally do not perceive the gap between switching presets as soooo bad..

And I am quite sure, it will get better with future updates.

You hear it, because there is silence while switching. If it wasnt, (as e.g. im kemper, where the gap is there but Firlefanz with spillover) I would not care at all...

Yeah I have a 3 channel amp I just cloned and to use 3 proxy clones it eats up significant cpu. Very similar to an agoura amp. 
 

had to cut some blocks out of my preset. 
 

top row: simple pitch (can’t use poly), compressor, phaser, 2 proxy clones

 

bottom row: one proxy clone, volume block, gray flanger, stereo elephant man, two stereo reverb blocks and the deluxe looper. 
 

so it’s not the worst. There is room for a few things but you definitely have to be intentional.
