Scene Switching latency

I have discovered that it happens when I change in the scene from the clean to the OD channel in the SLO100 amp (or viceversa). Maybe this is an expected behavior.

Yes, that’s the way it is expected to work.

same thing happens with some other amps in the QC. Such as when switching stuff like that with the Kraken model. You’ll need two instances of the amp if you are trying to switch between two channels on it. That’s just the way they programmed the models unfortunately

Hi Guys, I will sell my unit as there was never a solution offered for this.
Customer support basically told me “yeah, that’s the way it is ans stays”.
Good luck!

Yeah. They don’t care. What are you going for?

Can’t say I’ve noticed any perceived latency with scene or stomp modes… And I mite be switching a few blocks on each scene… I also recognise these type of amp switching latencies effect most modellers just reading a fractal post and they are complaining about the same thing… I also checked out a Marshall amp that is analog and they giving out about gaps in switching…and with the many amps I’ve had over the last 40 years it’s not somthing that would have stuck out to be somtin wrong I think it’s part and parcel of channel switching

This latency is much too long for live use! The whole point of using scenes is to get rid of that latency and instead have gapless switching between sounds. Otherwise you could just as well use presets. I tried it now with the SLO-100, first with switching settings in one instance and then also switching between 2 instances of the plug-in, even on different rows but there’s still too much gap between the sounds. I own and use other units like Kemper and Fractal FM9 and none of them has this problem. This can’t be a thought out strategy and I’m sure it can be fixed in a future update. Think about it: Why would any player want a gap of silence in their playing when switching sounds? What would be the benefit of that? Otherwise it sounds great and I hope for a solution soon because this is not acceptable in live situations.

There must be something wrong with your unit or preset. I don’t have gaps with scene switching amps…… I have a pretty full preset with multiple amps and don’t notice any gaps (always looking out for it though). Switching channels on my 5150 II has more of a gap

Maybe this helps:

I made a new preset with one of the new Deluxe amp models and one cab. 3 scenes with different amp settings.

No gap between scenes 1 and 3, but a big one when changing to and from the second one. The problem was that scenes one and 3 have the “channel” switch to one of the 2 positions, and the second channel is set to the other position (normal and vibrato, I think).

I’m almost sure if I use 2 blocks with the same amp I won’t have this lag.

Yeah you need to use two different amp blocks if you’re using the switches to change channels like that. If you’re switching between the amps there shouldn’t be any lag with the scenes. I suggested the same sort of fix earlier in this thread and I feel like the OP didn’t try that if they’re still getting a lag

Thank you all for suggestions. However, as I wrote in my first comment I tried both changing the channel switch in one amp block and using 2 instances (amp blocks) of the same type and switching between which of the two was active in different scenes but I had the same long latency in both cases. I also put the two amp blocks on different rows since I believe row 1-2 shares one processor and row 3-4 another one. That didn’t help either. I checked this with a Kemper today with no gap between scenes/rigs so I’m pretty sure it’s possible to achieve that on the QC also since it is supposed to have a lot more processing power. Hoping for a solution soon.

I’m experiencing the exact same issue on my QC as well. I’ve tried various presets and even used separated blocks, but the problem persists, even when there’s no amplifier on my grid. When I switch active blocks for reverbs, delays, or even some of the available overdrive pedals, I still encounter these gaps…

I’m sure the people at NDSP are reading this so could someone of you please confirm if you really think there should be a gap of silence when switching between scenes as someone in this thread claims? (Remember, a crossfade is not the same as silence, it’s a ramp from one sound to another.) I remember when professional Fractal users (as myself) complained about this and it didn’t take long before the issue was solved so I hope that this gap will be a short parenthesis in the NDSP history. An otherwise good sounding unit shouldn’t stay home while the other brands are on stage just because of this. Fix this please.

Not necessarily. We have our mod who overlooks the forum, and we have seen where NDSP have implemented feature requests that people have voted on, but it’s not like NDSP are keeping a close watch here. If this is such a dealbreaker for you, I would email them directly.

We’re all going down a weird rabbit hole on this topic. Many many many of us who play live don’t have an issue with scene switching latency. What one person insists is unacceptable, is perfectly fine for others or even better than the channel switching on real tube amps.

First: If you have a company that sells products worldwide and want as many people as possible to buy your product so you can earn more money you absolutely will listen to what the customers want. Therefore I’m sure the people at NDSP are reading this simply because they would be complete idiots if they didn’t, and they are not. I have emailed NDSP even before the launch of the QC since they put me on their pilot testing list. I will send an email to NDSP about this but this time I started here in the forum because I thought I did something wrong and was looking for a quick answer that solved my problem. If other users of the QC don’t have a problem with this latency, good for you but that doesn’t help me as a pro musician with around 120 gigs per year with different artists and the rest of the time teaching students on a high level who are asking me for directions in what unit to go with for their live performances. This is not a rabbit hole. I could actually live with something that sounded a little less good as long as when I press a button to get a certain sound (lets say going from a verse to a chorus) I would get it instantly without a 500 ms dropout. Believe me, on the level of artists I play with they would fire me (for good reason) instantly if I tried to explain why my gear is lagging and they would also say “Why do you let your gear let you down?” I can only say one thing regardless of who is reading this forum: FIX THIS IMMEDIATELY! Create a fast crossfade between sounds in scene mode. No one benefits from a gap of silence when switching between sounds and if you really want that silence, just stop playing and be silent for that part.

Share a preset showing where you’re getting this 500 ms dropout. Most of us really have no idea what you’re talking about.

We know about the SLO-100 plug-in block switching issue–that has come up in another topic in the forum–but I built a preset with multiple instances of the block with different settings and it solved the scene latency problem for me.

And the “I’m a PRO gigging musician” sabre-rattling doesn’t fly here, we’re all using the QC for gigs and dealing with its capabilities (and shortcomings).

I’m not saying that I play better than others so what I mean with the “Pro”-label is that you can live with some shortcomings of a product in some cases but when you are hired as a payed musician you just can’t afford shortcomings in your gear as an excuse for why you are late on a chord in a song for example. If you are fine with latency or use the QC in ways that there is no latency, good for you but please don’t debate my needs because they are what they are. I gig with both Fractal and Kemper so I’m not really in need of a QC but since I think they sound good and there is a potential of becoming a full-blown product with no disappointments I put some time in giving my input here. If I wouldn’t care I would just sell it and go with other brands. Why wouldn’t we all want this product to be the best it can be?

Share a preset so we know what you’re talking about. Maybe someone here can help.

A 500ms dropout seems kinda weird. Honestly don’t know how you’re getting that much of a gap. I honestly have zero gaps in my presets. I switch between a couple amp blocks + fx loop and various other blocks within the unit. It doesn’t happen live or in the studio. There has to be something strange in the preset or your unit.

No gaps here either. It would be nice to see an example of the preset to rule out a possible
hardware issue @JSJSJS
