Preset Change Lag

Hi All,

Had my QC for 2 days now and have raced to set up a suite of presets ready for its first gig tonight. Had amazing results so far and really pleased with tones I am getting. Only issue is that the lag when changing presets is really noticeable (will probably be less noticeable when the rest of the band is playing). I know I could get around this with Scenes but we have very quick song and sound changes and Presets will just work better for me.

Is this something that has been discussed by Neural at all and something that is likely to be ironed out in further firmware updates?

Thanks :slight_smile:

Presets will always have a little lag because every block has to be loaded. When the QC was released the lag was much more noticeable than it is now, so I can imagine that it might improve over time. But it will always be there.
You can can load multiple amps, cabs, and/or effects into one preset and bypass/activate/change them when needed in scene mode. That should cover all of your needs I guess :slight_smile:

Thanks for the reply. Yeah I think I will start looking in to this a bit more. I have an expression pedal hooked up too which allows for even more options. Just need the time to be able to have a full on play around with it.

Hi! How long is the delay/lag when changing presets please? I’m asking for an approximate value, for example is it less than 1 second, 1 to 2 seconds, more than 2 seconds? Thanks

I think it depends on what the preset that is being loaded contains (number of blocks and which blocks). Somebody please correct me if I’m wrong.

Makes sense as it would depend on the intensity of the blocks. Any off-hand idea of the maximum time perhaps? With some common setups (although I admit that this will be variable per user).

I can try tonight and give you a rough estimate. Never actually paid attention to the gap or it’s length because I only change presets between songs. For in-song changes I rely solely on scenes because I never needed more than eight different tones for one single song. Scene changes are gapless :raised_hands:

That’d be very helpful thanks!

I just recorded a track in my DAW while switching through various presets. Big ones and and smaller ones. The gaps in the recorded track are about 0.2 up to 0.4 seconds. So even loading a massive preset shouldn’t take much more than half a second at the most.

I hope not. This cortex is a keeper for me, but the preset changes are… not great. Depending on transitions, my changes are into the next song, but sadly this is not always feasible.

That’s just something that all modelers have to deal with as CPU is limited. Have you tried scene mode though?

I get the issue of changing presets for a quick seamless change of songs. The only way I get around this is trying to change to the next preset and to a similar sounds and switch between chords so there is t just a big ringing chord with half a second gap in it.

It’s not ideal but for the gigs I’m doing it’s not usually to musicians (mainly weddings and functions) so I can guarantee the only person that notices the lag is me

Yes… i’ve tried scene mode.

Its just easier (for me), macro, to maintain songs as presets, especially when you’re dealing with a large pool of songs (and setlists remain fluid). By no means is this a deal breaker… just not great.

As far as a comparison, my only applicable device to compare is the Eventide H90. Its “program” (different nomenclature) changes seem… less abrupt to nonexistent (except with synth tones - then you hear the hard break), but it doesn’t have all the bells and whistles. Thats why I have both. Lol

All things considered, I do believe there are creative solutions to this. I’m patiently excited to hear where it all goes… and i’ll still be rockin’ the QC!!!

Hi Fellas,
I have just seen the Youtube video where Kiko reveals his automated Megadeth live setup. He has been using PRESET CHANGE for every different parts of songs. This is done via computer automation. My question is: How could he manage that obvious lag between preset changes?

I was using my AX8 before QC. Amp X/Y change would take approximately 45ms. So I was sending MIDI CC messages to control amp x/y state change with -45 ms (track delay) from Ableton just to fall on the beat. Even in that situation , it would annoy me.
Scene changes in QC are much faster. And Kiko does not use even that opportunity. I am a little confused why such a big band’s player would not expect more while we users here give a fight for reducing those milliseconds :))

I have a detailed topic here:

Best wishes to you all

@DavidRSTV , I was actually thinking about this. I don’t know how much RAM the QC has and how limiting it would be to actually limit other things in order to be able to have 2 or 3 presets loaded into RAM so that switching is seamless.
Personally I do not need it, as Scenes work just fine for what I do, but I do understand that some of us would need this.

So far this is a major drawback to the QC. I used to use a Peavey Tubefex that was essentially set up the same way -

Dist on channel 1
Dist Lead on Channel 2

The only difference between these was that the amp would go about 15% hotter on leads, but the rest of the settings were identical.

Change times between channels was non-existent. So close to zero you didn’t notice.

But on the QC…it’s bad. Probably close to a second, maybe a shade less. True that when the rest of the band is playing it’s less noticable, but we just shifted down to a three piece, and as the only guitar simple changes from rhythm to lead sound AWFUL with the long lag time changing from Preset 1 to Preset 2.

Kinda sad, because I love the rest of the features and the lack of needing to carry amps and cabs to shows. But this is not even close to good for stage shows with this issue.

Is 1 preset per song with 8 Scenes not viable for you?
