Beta testing of Vult filters

I’ll check it. Disjoint should not change behavior with the sample rate. I did a quick test with Bleak and I did not see a difference. Maybe you can check as @Squinky says, setting the quality to Ultra. I’m not able of changing the quality on the Mac M1 because it crashes Rack.

hmm, doesn’t crash on my M1, what version of BA modules do you use? BO version 2.4.44 here, also MacOS 14.2.1.

There is definitely a sample rate tuning issue with the m80 Disjoint patch. It is easier to see if you also attach a scope.

I tested all the available sample rates on my Windows 10 machine. As I sweep a fairly narrow range of the Disjoint cutoff frequency, I get similar behavior for all sample rates, except the precise knob position where certain events occur varies with each sample rate. I think generally as the sample rate rises, the required cutoff frequency also rises.

So I can tune Disjoint to get a particular behavior for a specific sample rate. But then when the sample rate is changed, I must retune Disjoint to get the same behavior.

I tried to capture a video, but the recording stopped everytime I change the sample rate.

I’m using the same version. I’m running Rack for arm64. It could be that it works with Rosetta.

The Analyzer XL works fine. It’s just eh original Analyzer that crashes.

I have a crash when a signal is connected and change the setting. When nothing is patched, it works.

(I changed the ultra mode to default, so no more crashes for me)

I also run the arm64 version and both work fine here, with Basal connected

The Analyzer doens’t really matter.

Look at the VU meter of the Audio module. It clearly shows the difference when changing the sample rate. 96kHZ is LOUDER, so presumably the filter cutoff frequency shifted.

In an actual “musical” patch you can clearly hear the difference, which is how I noticed it in the first place. The sample patch just reproduces it in a very simple manner.

This behavior shown above is on Ubuntu Linux, but it is the same behavior on arm64 M2.

Side note: also reproducing the crash in Analyzer on arm64. I filed a bug report for that.

I’ll try to fix it for next release. I cannot see the bug in my code and I have to re-do all the calculations. to find the mistake.

Thanks for bringing back the scream. That grit sounds so good. Thanks @veryfungi for sharing that little screamer patch.

Everything is back to normal. Yippy I used it more in this recording.
