Will Stadium ever have seamless preset switching?

[Nos402]

At the moment when you switch presets, there is silence for a brief moment while switching. Not a big deal to me as I only really use one preset per song, but I imagine this could be a problem for some folks. I'm just wondering if that's something that might come in the future, or if it's just beyond the capabilities of the Stadium due to processing power and such!

... on the Helix you could enable reverb and delay tails to "eliminate" the silence between presets. But you sacrificed the second line of blocks in all your presets to ensure there was enough processing power to handle these tails and switch in the new preset. I haven't got my Stadium yet (2 hours to go) but I'm assuming something similar will be available to enable.

A brief audio gap is unavoidable as a new preset is loaded using a single DSP processor. This isn’t just a Helix or Line 6 issue; it’s a technical reality. It takes a few ms to load new data into one fixed memory space and all computers/processors experience it.

 

Helix is able to avoid this beause it is a dual processor device. Line 6 has implemented a feature called Preset Spillover in Helix that eliminates the gap. However, it’s costly from a DSP perspective. It requires that a user sacrifice 50% of DSP capacity - one of the two processors and the dual-path preset structure. When this feature is enabled a new preset is loaded into the unused processor/path while the used processor continues to operate. Hence no gap.

 

The Preset Spillover feature is not (yet?) implemented in Helix Stadium.

When the feature is released, will it be possible to view the current DSP % load per preset in order to being able to make informed decisions on whether to engage the option or not?

True "Preset Spillover" is a feature that currently exists on the OG Helix. But, as stated by @stuming, you sacrificed one of your DSP processors (50% of your total available DSP) in order to get that. It's great for using multiple presets that don't require more than one DSP processor.

 

I have not heard anything from Line 6 on IF they are going to support True "Preset Spillover". But, I would assume that it would follow the OG Helix in that you would need to sacrifice one of your DSP processors in order to do so. Line 6 could provide this functionality later as they did with the OG Helix but they are very silent on future functionality - No one wants to anticipate a feature that never comes - or comes much, MUch, MUCH Lat-ter.

I just upgraded from the PodGo to the Helix Stadium XL. Man what an awesome piece of engineering! I know the very first post in this thread states that changing between presets will always have a delay, and I also know it's not a apples to apples comparison by any means, but my PodGo is very fast when changing between presets! Even some of my very heavy DSP presets are no issue, almost instant change. So far I have only tried the presets included with the helix stadium xl and at first glance they didn't appear to be that heavy, so I was really caught off guard with that delay. I'll try to build a couple of the most basic possible presets and see if there's any noticeable difference between them and some of the heavier ones. Right now that's a showstopper...literally. I am confident Line6 will figure something out. I bought the stadium without concern about support as I very much see and appreciate how line 6 has continued to support all of their products throughout the years! I'll do my best to be patient :-)
