How to load only one rackspace at a time in a setlist?

you could use keycape in the global Rackspace.
But then you have to take care that different Keyscape presets are loaded when you switch rackspaces and need a different sound.

Did you activate preview in Keyscape, this way you save RAM?

That’s a great idea! I’ll have to figure out how to route that exactly, but the set it is one Keyscape rhodes across the whole set list as the sound source, so the global rackspace should work!

How do you activate/deactive “preview” in keyscape? This is a setting I haven’t come across in my research

What sample rate and buffer size are you using?

44.1khz, 96 buffer

What latency is shown in the audio Settings?
What Audiointerface are you using?
What is the spec of your machine where GP running?

I haven’t figured out this one yet either. But I did come across this page that might help some…

I do not have the details, but I think there is a system button where you can enable “Thinning”

I’m using a focusrite scarlett 2i2, this kind of laptop – I’m at my studio right now where the laptop isn’t handy, but the latency is noticeable at 96 buffer. Not terrible, but noticeable

Really with 96 sample buffer size at 44 kHz?
What latency is shown in the GP Audio Settings?
How is the real overall latency?
You can easily measure that with GP

I’m at my studio without the laptop here, I’ll have to measure when I’m back home, but it is noticeable. If there was a way to tell GP to only load one rackspace at a time, that would be the easiest way to handle this. It seems like the global rackspace is the next best option! If you have any other ideas, please share!

Why do you think to load only 1 rackspace solves your latency issue?
Try this test:
Export the rackspace.
Create a new empty gig and import the rackspace.
Now you will see the latency is the same.
Do you use an ASIO driver?

Meh. Go to 128 or even 160

My pro guitar friends (using in ears) work at 192 or even 256 with no issues. In a double blind test, I doubt anyone could tell the difference between 96 and 128

I’d be more skeptical of your audio interface not being up to the task of handing those lower sizes. A decent audio driver makes a huge difference

It probably won’t. This feels more like an audio driver issue not being able to handle the lower buffer size. Or maybe the computer isn’t up to it.

I have heard this often. I don’t know about guitarists, but as a piano player, when playing keyboard sounds (Rhodes, etc) I can not go above 128 and definitely prefer 64. I can’t say that I necessarily hear the difference but I most definitely can FEEL the difference (though that clearly is part of hearing it). It just feels sluggish, I can get used to higher values after a bit, but as I often switch between the internal sounds of my keyboard and the sounds in GP the difference is always noticeable.

I wish it were not the case. Having to run so low definitely puts me right on the edge, even with a new pretty well spec’d laptop. IK B3X is the main culprit, worse than Diva.

Someone wrote above that RAM has no effect on latency, is that true? I also have little use for predictive loading. Even if that doesn’t effect latency, I’d prefer some option of not loading multiple instances of plugins just to make startup quicker. Is that something I can do with global rack space? I’d still want different configurations of plugins and presets etc

I play both though I’m primarily a keyboard player. I usually play at 256 and while I can tell it’s not “instantaneous”, it generally doesn’t bother me at all. If I have something really percussive, I’ll go down to 128 and then it most certainly feels instantaneous.

When you say you can feel the difference, have you really done a proper double-blind test? Just knowing the settings can impact what you think you feel.

The reason guitarists would be even more sensitive is because they can hear the physical string when they pluck it so even a slight delay before the processed audio arrives is instantly noticeable. Also, for every foot of distance, that’s about 1ms extra delay.

As @pianopaul mentioned, you should see what the actual latency is with your audio interface.

By definition, excluding your interface, the actual latency for a 44.k sample rate and 128 buffer size would be 128/44100 = 2.9 milliseconds and you’d have to be superhuman to notice that

Well I use an Apogee Groove, as has been discussed on here previously. It is just a stereo DAC so I can’t test latency, with that test anyway. I understand it might not be up to snuff, but the price ($249 and just paying for the feature I need it for, stereo DAC) and the small size make it worthwhile for me. It is a well regarded company and they have their own ASIO driver for it. I am running at. 64 samples so it must be doing something right.

But as I said it’s right on the edge. If I can find any other little thing to address the issue that would be helpful, which is why I wonder about not having to load many multiple instances of plugins. And as I mentioned even if it did not help latency it sure would speed up start up which which would be great. I understand the predictive loading is invaluable to many, it just isn’t for me.

I have never done a double blind test, but I am confident of my perspective. I’ve had too many circumstances that were the equivalent of double blind as I wasn’t thinking about latency or anything of the sort and knew something was off. I wouldn’t bet my life on getting the difference between 64 and 128 100% but going from 128 to 256 is easily noticeable to me

I wouldn’t really rely on Windows Home for your Pro purposes.
Although we have a guide to optimize your Windows PC: FREE e-book by Deskew - Optimize your Windows PC for the stage!
This might not work on the Home edition, as it is more “locked”.

My suggestions:

  • RAM upgrade
  • Windows upgrade to Pro

If this is not an option, follow the abovementioned guidelines, see what guidelines work on your Home edition to free up your RAM and CPU cycles.

Also make sure to run Gig Performer Latency tool: Latency measurement tool


npudar, I also am running WIndows Home on my Dell. I am curious what can’t be unlocked versus the Pro edition? Is this referenced in the Optimize WIndows PC for the Stage?

The Home edition is not mentioned.

For example there are less possibilities to control the Windows Update on Windows Home.

Let’s remember that a song will always be loaded fully!

That means that if you set predictive loading to 3 and your song uses 6 rackspaces - all 6 will be loaded.

The reason is obvious - you don’t want to be loading stuff mid song.
