Dyna Cab issues?

Hey friends, just updated my FM9 with latest, and created some Dyna Cab powered presets that sounded awesome at home.
Off to the gig, and when I engaged the two presets with dyna cabs, they sounded... farty. IDK how to describe it, fuzzy, cutting in and out, just not good.
I switched over to other presets I have, my go-to, and another newer one, they sounded great. Those have regular legacy IRs on them.
So, am I having an issue with CPU in the dyna-cabbed presets, was it too hot? (yeah it was pretty warm out), was the sound guy screwing me?
Just wondering how everyone's experience has been using dyna cabs live. I have 80 and 10k lo/hi cuts on all my cabs.
 
You’ve described multiple issues here...

“Farty” usually means too much low end. “Fuzzy” usually means too much high end or distortion. “Cutting in and out” usually describes a connector or cabling issue. “Just not good” gives nothing to go on, so I can’t use it here.

My first thought is that you dialed in your tone at moderate levels, and Fletcher-Munson grabbed you by the short hairs when you turned up to gig levels. The fix there is to dial in your tones at volume, preferably in the full mix.

As for cutting in and out, double-check all your cables and connections. Is it a CPU problem? Have a look at how much CPU you’re using, and that will tell you pretty quickly.

Thanks Rex for your notes to help me troubleshoot. Yeah I mentioned I have hi/lo cuts because I also would be concerned about too much low/high end. Also I told the sound guy even though I had lo/hi cuts, he could do his own, and he did. I thought it may have been my wireless, and I replaced batteries and re scanned. Same issue. Only the dynacab presets experienced this. I will be running my own sound this weekend and I'm going to give it another shot, also I will open fm9 edit and check the cpu usage. I've never come close to cpu limit on this unit and I have a handful of blocks on there. Mostly want to know if anyone's heard this. I might be able to pull some audio from friends in the audience.
 
Go beyond the high and low cuts. Actually dial that guy in at gig volume, and then apply the cuts.

While you have your rig at home, see if you can make the issues happen again. And definitely post a clip if you can.

Totally understand about 'gig level' preset making, but I've had great success creating at home and using live, with legacy IRs. My go-to, and the other preset I made at the same time have legacy cab type and sounded really good.
I also use the preset level tool to make sure they all are in the same range. I will dive deeper into the dyna cab menu. Possible user error there since I'm new to that. I don't have time today to set up and blast it out but will definitely report on tomorrow. I have more control of the PA and can see what's going on with levels and RTA. Thanks!
Also maybe I just screwed up the amp settings in the dynacab powered presets and the amps themselves are misconfigured... totally possible :D
 
I like your 80hz low cut, I think that is a good default number to start with.
Ever since becoming a Fractal nut, I was afraid to go below the 6-8K High cut because of what I saw all the experts doing.
Then one day someone posted that he cuts his high end to about 3500hz. I couldn't believe it!
I tried his suggestion and have not looked back! My treble is just right. Each IR will be different. So...
Many times I do the low cut in the Amp Block Input EQ. I really like how this tames the lows right from the beginning.

3500? Interesting.
This weekend I was looking at the Celestion response curve on their site, so I'm looking at 75 to around 5k. Usually I do 10k, I will try to go lower. Just for fun :)

I played this weekend and I didn't experience as bad a tone as in my show last week on the dynacabbed presets.
To recap.... I had two presets with dynacabs that didn't sound great; an AC20, and a Princeton. The AC20 sounded great over the weekend. Almost too chimey, actually! Gonna get some hi cut in there on the amp. The Princeton is the issue. I heard the low end growl, but, it didn't fart as much, LOL. I could still not use it comfortably.
I'm beginning to think the Princeton was not configured properly, and combined with a not-so-great monitor that the sound crew had last week, it just kind of sucked.
I am going to start from scratch on my Princeton preset and spend more time in the dyna cab menu. I'll pull the gain down and bass, and generally look at the wiki for recommended settings.
Additionally, any video I heard from the audience, actually sounded ok. I really should bring my own FRFR speaker when I am using house/city sound crew, just in case this happens again. Thank you for your thoughts on this.

Keep us posted!
 
It's interesting how different experiences can be. I upgraded last week and dialed in dyna-cabs on my base preset scene and, holy smokes, it sounds amazing. I just need the time to dial in more DCs for my remaining presets and scenes.
 
I got my FM9 (had the FM3 many times and even a first rev FM9) and built my preset and thought it sounded great.
I didn't know how to setup dyncab, figured it out and my mind is blown... I mean, it literally sounds exactly how I experience playing through a regular cab. And I can compare directly because I do BOTH for testing.
Pretty amazing!
 
I just got my FM9 and can’t seem to find the Dyna cabs. In a preset when I click on the speaker I get Factory 1,Factory 2, Legacy, Scratchpad and User. No option to select Dynacab. I’m on version 5 firmware for the FM 9 and version 1.02.04 for the editor. Do I need to download the file? When I boot up I get the message “Loading Dynacab” and “Decompressing Dynacab”. I’d really like to try them out.

I've usually been a cut at hi-cut 7500-8K person, but thats to retain the top end sparkle and usually a starting point. Most live presets I do go as low as 5k. If it sounds good, it is good.

For what it's worth, when I installed the Dyna Cabs onto my Axe-III, FM9 and FM3 the first sound that I had on all three was fizzy like the cab block was bypassed or no IR was loaded. I was not impressed and moved the mic positions around to try and improve it and all it did was get darker. So I switched back to my legacy cabs and continued on with what I was doing just thinking that the Dyna Cab hype was not for me.

Then on another day I powered up again and tried the Dyna Cabs just for the hell of it and everything sounded amazing and I have been using them ever since.

The only thing that I can figure is that the is some SW/HW bug or interaction that has to be cleared by a power cycle of toggling the cab block on/off or something like that.

Everything since has sounded amazing and the Dyna Cab modeling is a noticable improvement for the cab block.
