Hi, yes definitely had this issue as mentioned earlier in the thread, also sent a support ticket, to which I have had a reply confirming the issue. As an aside great customer service

I'm referring to the "CPU usage spikes over time with various hosts" issue mentioned by one or two people. Not Studio One V2 Channel handling issues.

This is with Stereo tracks, not mono tracks?

Well it is not designed as a "dynamic playable instrument". It is designed to be an algorithmic reverb. Several parameters are not continuous in design. We intend to improve automation of the ones that are in the future.

antithesist wrote: CPU ranged from a few percent to a little over 50% other than the spike incident. It certainly offers more control than any reverb I can think of playing with, ands begs more understanding of what some of the parameters are actually doing in physical terms. It was worth spending some more time with and left a better, less daunting, impression this time. I guess it just takes a lot of CPU for certain things. If fact, I can't think of another plug-in that varies so much in its usage.

CPU usage in B2 varries drastically depending on preset. It depends on (in order of importance):

0) single vs dual engine
1) current oversampling ratio
2) density/diffusion mode (nano, lo, hi, xtrm: each is roughly 2x as heavy as the previously)
3) modulation density mode (lo, med, hi)
4) density knob (negative values use less CPU)
5) attitude (some choices are heavier than others)
6) dynamics processing on/off
7) eq and damp filter choices

Xtrm density/diffusion mode is quite heavy on the CPU. Particualrly with oversampling. If you want to use it I recommend setting modulation density to med or lo to compensate.

Of course when various parameters are in the disabled state they consume no CPU power so this is a factor as well.

The range between min and max CPU usage is quite drastic. It might even approach 100:1 or so... More is not always better. Use your ears before just setting everything to max. (And note some presets that I made in Dual engine ARE set to max... Many of the 4C presets are pretty heavy if I remember correctly...)

Thanks, I think you had said most of that stuff before. I tried mousing with my ear, which is no small feat, and I still got high CPU usage and clicks at times.

I did. I cut/paste...

That will teach me to reply when I am in a hurry!!

Stereo tracks were fine, just had the issue with mono track!!

Hi,

B2 is my dream reverb. Long looking for best reverb plugin is now finish. Bought and happy user.

I just tested with Studio One v2 latest build on OSX.6.8. I do not notice any issues with STEREO tracks.

I do notice issues with MONO tracks, and we are aware of this issue: namely channel handling is different than expected for mono-tracks and this causes us some problems. At the moment Mono tracks are not supported for Studio One v2. We will fix this.

But I do NOT find the issues you mention when using STEREO tracks. I do notice that CPU usage spikes up immediately when changing presets but this is only for a few tenths of a second while we are loading the preset and setting various internal parameters. This is normal. Once setup is complete CPU usage seems normal and varies according to preset.

So I ask again: anyone else have issues with STEREO tracks in S1 v2?

Dry source is a pure sine wave synth playing some evolving chord structures...

B2 preset is "Special Effects | FX 3 Mystical | Adrift"...

...edited slightly to add some Attitude/Distortion to both A and B engines...

Beautiful sounds from B2 indeed.

Andrew, it seems from comparing the controls in Breeze to B2 that the shape control in Breeze is replaced by Range, Random and Curve in B2. Is this fair to say? Or was Shape split up into a couple of them and random was added?

Just trying to understand how one would go about affecting the equivalent of "Shape" in B2.

Thanks

Shape in Aether/Breeze translates to Range in B2. But Shape/Range for all three products behaves differently. Each has it's own unique character.

In B2 Range is literally the range of delays from the smallest delay to the largest delay. You can think of it this way:

Size determines the largest possible delay. (well really it scales all delays)
Range determines the smallest possible delay.

Random and Curve determine where the rest of the delays are within the bounds of the largest and the smallest delay.

In B2, the allowed range for Range is literally 0% to 100%. If you have 0% range all delays will be the same. Actually they can never be exactly the same for other reasons but they will be very close depending on other controls. At 100% range the delay range is from the absolute smallest delay we allow to the maximum defined by the current Size setting.

There are plenty of other subtleties, but this gets into IP territory...

The Tap Display exposes this stuff to a great degree. It is VERY powerful and helpful to understand how things work, and how to design presets, and how to make the A and the B engine work well together to form a unified preset.
