Dragonfly Reverb Bug
Hi all. There is a discussion on the Ardour forum about a bug in which Dragonfly Room occasionally blasts a high-decibel noise. Naturally this is very concerning to anybody who uses the Dragonfly plugins and values their hearing (which is certainly 100% of the people using these plugins). In the past I fixed a bug with similar symptoms, but I think this is a different bug that causes the same problem.
I need help narrowing down the cause of this bug. Anybody who uses Dragonfly Reverb:
Which Dragonfly plugins do you use?
Have you ever experienced a blast of noise from one of the Dragonfly plugins?
Have you experienced this bug recently? (Let's say in the last six months)
Which plugin exhibited the bug?
Do you run multiple instances of Dragonfly plugins in one project, or a single instance?
What plugin host do you use?
What CPU do you have?
Thanks everybody.

Re: Dragonfly Reverb Bug
I've never seen that behavior, and I've been putting Dragonfly to heavy use during the past year. Usually a mix of Hall and Room, occasionally Plate, always with multiple instances. Almost always in Ardour. CPU? Not sure offhand. It's a dual-core 64-bit that came with my 2013 all-in-one Dell Inspiron.

Re: Dragonfly Reverb Bug
You know the rest of the details since we've been in communication about this, but my CPUs are:
Intel Core i3-6300
AMD Ryzen 7 3700X (my main PC on which I've done most of the testing)
I should add that the project has Hall on a buss with the dry set to zero. I don't know if that affects this or not since we were talking about that other potential bug, but maybe the code doesn't "like" that slider set to zero.
I also haven't been testing Room for this (nor the others) in months.

Re: Dragonfly Reverb Bug
I just launched a project in Mixbus32C and the noise ripped me out of my seat.
This is the first time as I've used Dragonfly for sometime now. This is with Dragonfly Room.
It's like static on an old tubed TV. It's loud too.

Re: Dragonfly Reverb Bug
With help from some folks who discussed this bug with me on Github, there is now a new version with a fix for a bug that could cause bad behavior upon loading the plugins if any dials or sliders were set to zero.
Please download Dragonfly Reverb 3.2.3.
For anybody interested, I made a bad assumption that the constant FP_NAN represents "Not a number", but in reality it is just an enum value that equals zero. You can see the fix here: https://github.com/michaelwillis/dragon ... 5a2a318fff
Edit: Updated link to 3.2.3 instead of 3.2.2 which was broken because I was in too big of a hurry to release it.

Re: Dragonfly Reverb Bug
Let me know how it goes. Please be aware that I originally posted a link to 3.2.2, but it was broken because I was in too much of a hurry to release it. I have updated the download link to be 3.2.3.

Re: Dragonfly Reverb Bug
Somebody in the REAPER forum mentioned that dragonflies feed on large quantities of bugs.
Maybe I should have picked a different name.

Re: Dragonfly Reverb Bug
Dragonfly Hall and Room primarily. I'm not the best at getting good plate reverb sounds.
Until my upgrade to Ardour 6.5, no. Then suddenly, every single project with a purely wet verb would peak the meter ... but no noise actually came out, because I bus that shit.Have you ever experienced a blast of noise from one of the Dragonfly plugins?
YesHave you experienced this bug recently? (Let's say in the last six months)
Both Hall and RoomWhich plugin exhibited the bug?
This has happened with both single instances and multiple instancesDo you run multiple instances of Dragonfly plugins in one project, or a single instance?
Ardour primarily. When using Dragonfly within Carla I have zero issues - but I also don't run a pure wet signal in Carla either.What plugin host do you use?
Thanks for putting in the time to track this down.What CPU do you have?

Re: Dragonfly Reverb Bug
Hey @uns4ph3, please try the new version 3.2.3 that was released today, I think it will likely fix this bug.
