H90 latency Program Change

I’ve also experienced latency when switching programs. The spillover does help mask it, but it is not instantaneous and I’ve had to switch ahead of the part when when changing programs. It’s really obvious when you click on a button and it doesn’t engage until your foot is almost back on the floor.

Digital pedals will always have some latency for loading the next program. (Note that you won’t have the same issue when switching off and on, either with digital or analog pedals)

The H9 also lagged when switching between algorithms (the time dependent on the algorithm) and would drop out between algorithms.

In short, I believe that this is just how the pedal is.

You can try changing the Spillover setting to a lower value and this may improve the time between changing Programs. You may also find that using the onboard footswitches in Select Mode will be more immediate than using your MIDI controller.

I’ve had this exact experience, which is a real bummer because I’d hoped that the H90 would be the all-FX-in-one unit I’d dreamed of. But the momentary signal dropout when engaging/swapping between presets is so noticeable that I’m going to sell mine when I’m home from tour in three weeks. Really disappointing considering the fact that gapless switching was touted as a selling point.

I haven’t done a scientific comparison, but the latency seems a bit better after the new update (1.5.2)

From the release notes:  “Users will notice significantly reduced latency with onboard footswitches & external controllers, especially in timing-critical scenarios”

Can confirm that the “gapless switching” is still anything but even after the newest firmware update. Switching + engaging a preset via secondary controller sending a MIDI command also produces an audible gap. If I weren’t on tour right now I’d already have this up for sale. Seriously disappointed in the H90 in this regard.

I can also confirm the latency as mentioned above. But I actually think it’s worse when going from bypass to active. I tried to change the spillover but it didn’t have any effect. I have the H90 connected to a serial FX loop on a guitar amp.

I’m looking forward to a fix.

Thanks

I’m also experiencing latency and an audio drop when changing programs. It’s not a complete cut, but there’s definitely an audible drop.

I’m only using the H90’s footswitches, but changing programs is not instantaneous as the manual suggests.

Using the latest firmware 1.5.6

I recorded a short video showing the audio drops when changing programs:

In summary, therefore, the slow midi communication does not seem to be the problem, perhaps the algorithm loading process should be optimised/speeded up.

I’m relieved that I’m not the only one experiencing this, but I’m also sad that the fix isn’t as simple as getting a replacement unit. Between this and the ongoing lack of mobile app for control/editing, looks like my h90 is on its way out. Maybe I’ll revisit it down the road after some updates, assuming that updates remedy this problem, but in its current form it is unusable for me in a live setting.

It might be helpful if people that experience lag to post what algorithms are in each program you switching between? Maybe some algorithms are more difficult to get seamless? Maybe the presets have different routing and the dry path is being broken?

I notice lag going from a program with a reverb and delay in parallel to a pitch and delay in series. I find most of my programs that are just reverb and delay in parallel switch seamlessly.

I wouldn’t expect two completely different algorithms to not have some glitch when switching between them. And then if they also have different routing? I think there are some circumstances where expecting completely seamless switching might be unrealistic.

Yeah, it’s horrendous!!!

I’m a sales engineer for this product and I’m shocked after being alerted to this issue. Eventide, please fix!!! Here’s a video with tails off and 0 seconds of spillover. Video is currently unlisted.

Recently picked up the H90 (new) and after programming with Morningstar MC6PRO, I am seeing/hearing the same latency when switching programs.

It is more apparent when using a midi switcher and going from PC change to PC change.  Very apparent.

In a live situation, this could be problematic. I’m getting about the same delay as the video.  The video pretty much shows the delay…and you can easily hear it.  I would guess it’s about around 700 ms.  There has to be a fix. I had a delay like this once with a midi switcher and an adjustment to a time parameter on the midi switcher fixed it, but that was 15 years ago.

Continuing my thread from yesterday, I’m spending a few more hours tweaking/programming Morningstar M6 pro.  It’s such fun.  A few things….some people are saying they’re going to sell their unit  because of the latency issue.  I’m not that great at midi programming, but there are definitely work arounds.  That is what is fun about doing all this.  I can understand if something just doesn’t work, but the trade offs you would make are worth it in H90 midi switching.  The sound and power is just to high of level.  If you need a tone such as chorus or pitch, or delay etc… have it ‘part of a program and just bring it up by active/bypass.  This is simple and fast. Then you can ‘switch programs’ when practical.  So far this is the apparent work around for latency issues IMO.

yeah, this latency issue is pretty crippling for me for live scenarios. Is it a software issue that can be fixed in a future firmware update? I’d be really sad if I had to sell because of that. Everything else about this pedal is magnificent.

Just adding to this that I am noticing a lag / dropout when switching programs in bank mode.

Any news about this?
I use a midi switcher and the delay until the program is actually switched is a real problem here 🙁

Ok actually I think it works fine now, at first I saw the visual response and also had some other issues with the MIDI that made it look and sound like the program is loaded after a really long delay through MIDI.
But then I checked it further, and in fact the signal of the new loaded program (which is what matters the most) is already heard a while before the program is visually loaded on the H90 screen & leds, so the response itself is pretty much ok.

I want to test it a bit more to be sure, but for now seems like the H90 is doing the job also for live scenarios and programs switching through MIDI.
