Itās interesting I canāt comment on Dyna yet as I am FM9 , but Marco on his live stream thought he got way too much low end with the 121I canāt get anywhere near the low end from dynacabs. And Iām still messing with them.
Dynacabs are 20ms and Ultrares are 170ms. I hear a difference.
My understanding is, that while Dyna Cabs are basically multiple 'traditional' IRs of a speaker, Fractal has discovered a new method of capturing IRs as well as the use of a robot to shoot them. It's not just a UI for selecting IRs.
I'm used to using the proximity in the cab block to thicken it up a bit. This is gone in dynacabs as you are doing the proximity manually with the distance from the cab with the mic. but it's not the same amount. It's not super bassy but it just adds some low end girth, chunk if you will.Itās interesting I canāt comment on Dyna yet as I am FM9 , but Marco on his live stream thought he got way too much low end with the 121
And suggested not using it with a 412 as itās to bassy

There are comments Cliff made that suggest there's more to it:There's not a new way for a mic to pick up sound from a speaker, that's the same as it ever was. While they may be programming the rig in a specific fashion, the result is an IR and robot mic rigs have been around for a while.
Now...they are offering phase alignment/correction when using 2 IRs which is nice but that's offered to some degree by some 3rd party vendors as well.
The tech/benefit is in the UI.
How about this? I was able to dial in a very heavy rhythm tone with a lot of low-end with DynaCabs.I canāt get anywhere near the low end from dynacabs. And Iām still messing with them.
No idea what you're getting at. The way in which IRs work is novel and been around forever and in tests have been proven to accurately capture and be indistinguishable from a miced cab given the same monitoring situation. I already acknowledged the phase thing is a nice addition, but that only impacts 2 mics mixed together (and IRs could be manually adjusted with the align parameter previously). It's no surprise that if 3rd parties want to load their cabs into Fractal's system that they'd need to rent out the system to ensure uniform implementation of the mic set up ensuring the ability of the UI to function with expected results as well as to implement the phase alignment piece and have it work with the existing dyna cabs.There are comments Cliff made that suggest there's more to it:
In response to the Line 6 release of their new cab - "FWIW we've been working on something like this for the past six months or so. We have several robots that we use for automated IR capture, custom control software, etc., etc." https://forum.fractalaudio.com/thre...-needs-to-catch-up.188394/page-3#post-2337208

Cliff didnāt say they were better, just different and that he preferred the sound of the Neve over the API :I remember seeing that they were new captures with the robo-mic and a better mic pre, or something to that effect....
Tonās of tests have been done on IR length. Iāll link just one great example from Pete Thorn .
20ms is plenty to capture the full speaker range. Longer IRs contain some amount of room detail in them. This can give an impression of fullness. Likely, you are hearing more of a difference between the full gamut of capturing differences: mic placement (we donāt know where in the factory IRs), mic pre, etc.
Edit: My argument is not whether DynaCabs will replace IRs. There will always be room for both. Hard to capture every speaker you might want in DynaCab format due to time to capture and storage requirements for them. TwoNotes, for example, created a custom format that does this too. They still support legacy IR formats and people still use them. My argument is that 20ms not being enough is ridiculous.
a longer IR length is not always best for everyone in every circumstance - Fractal has also said: "FWIW, I almost always reduce IR length on my personal presets. Usually 512 or 1024. I like the lack of reflections".Whether that difference ultimately translates to a recording is hard to tell, but my philosophy is always record the best signal available.
Enough for what? Live, sure. Recording? Not sure. When I listen on HD600s it's night and day. Whether that difference ultimately translates to a recording is hard to tell, but my philosophy is always record the best signal available.
I'll quote Cliff: "The problem with conventional IRs is that they are too short to capture the detail in the low frequencies. There are those that maintain 20 ms is the maximum length you need to fully replicate the speaker. This would be about 1000 samples at 48 kHz. I disagree with this as I have many IRs here that exhibit significant energy beyond 20 ms. I believe the room has some influence as the low-frequency modes of the room will impact the resulting sound. The amount of this impact depends on the room, the mics, distance, etc., etc. Or perhaps certain speakers have particularly high Qs in the low frequencies. Regardless, it is my opinion that you need IRs much longer than 20 ms to fully capture the "mic'd amp in the studio" sound. My tests show that IRs of 8000 samples are required to fully capture the low-frequency detail. Unfortunately to process an 8K IR in real-time require copious processing power... Fortunately I have developed "Ultra-Res" cabinet modeling. Ultra-Res cabinet modeling provides the frequency detail of a very long IR with little or no added processing power requirements."
