the preset change is very fast, so you should have no issues with any delays with patch change.  I don't notice any delay at all.

there is a free editor called POD HD Pro edit.

I hope this helps

Hi jonnytrip

What I actually said above regarding patch switching relating to the POD HD Pro was this:

I have one here.  In my experience it doesn't exhibit a significant delay between patch changes.   However neither do my Spider Valve MkI or MkII amps - and I know some apparently do.  

Any device that uses a system of stored patches which recall amp modelling and FX settings is bound by the nature of the physics involved to have some latency when changing between patches.  It is unavoidable and the best you can hope for is ultra low latency whereby any lag is unnoticeable.

I don't notice any delay with the POD HD desktop, POD HD500 or POD HD Pro. However I always tend to change patches between songs mainly or on the beat within a song if I have to make a change.  I don't tend to leave a note or chord hanging whilst I make a patch change.  If I were to do so then I could expect some evidence to come through that I'd made a patch change in the form of a change in tone more than anything but possibly an almost imperceptible gap. 

With respect I did not mention ZERO latency or ZERO lag in my reply to you here.  There was no BS in my reply in any way shape or form.  I spelled it out very clearly.  I don't notice any perceptible latency.  If I did I'd say so.  I did take great care to pont out that the best you can hope for is ultra low latency switching.  I also pointed out how and when I tend to switch between presets AND that if I were to leave a note or chord hanging during a patch change I could expect some evidence to come through.

As far as the Spider Valve MkII goes - again NO BS there either.  MY SV MKII does not exhibit a noticeable gap when I change between patches.  Maybe yours does.  I've never disputed that some SV MkII amps might display this characteristic.  Mine doesn't. Period.  From what I recall about the debate over that problem over in the Spider Valve forum, some users said they had a problem and others said they didn't have a problem.    If my SV MkII did display this problem and it was a problem to me I would have said so.

Your mileage clearly varies from mine with your Spider Valve MkII, but is your experience any more or less valid than mine.  Have I ever suggested your experience and what you said about your SV MkiII's patch switching latency was BS or that you're being too demanding in your requirements?  No I haven't  

Your mileage may also vary from mine in relation to the POD HD Pro when you get to try one, so really there's only one way you can satisfy yourself as to whether it will meet your requirements and that is to try one for yourself and based on what you find you can decide whether it's for you or it's not for you

I can only tell you with any degree of certainty what my own experiences are with my own gear - the same as anyone else can do - and that's all I ever try to do

i'd post a link of whatever accusation you're making or i'm inclined you're the one full of BS.  Rowbi and Nick are two of the most helpful, if not THE most helpful, people in this forum.

i would say the dropout between patch changes is certainly perceptible, but still pretty darn brief and by no means any kind of dealbreaker.

 

The only way around a brief dropout for a digital device as such, would be to have both the patch you're changing from and the patch you're switching to be functional at the same time during a transitionary period where the tone is cross-faded from one to the other.  This means any single patch could only use half of the available DSP.  I think most users would prefer that patches use all available DSP.  Thus for changes the current patch is unloaded, then the new patch loaded, meaning there is a necessary dropout during a patch change.

Hi Meambobbo,

that's a very good explanation of how it works.  there's no way around that with DSP and in some tube amps where they're switching to different tubes in the signal path.

Here's an interesting article about Marshall amp's switching delay being around 50ms.  there's also an interview around on the internet that I heard a few weeks ago where Santiago (one of the senior Marshall designers) explains that the slight delay on some of their amps when switching is to avoid a loud pop.  the JVM410H is fast switching but just audible... but the new Joe Satriani 410H has a built in noise gate, so they used that to mute the pop, meaning they could get a faster channel change.

Cheers
