Axe-Fx III Firmware 19.00 Beta 1

[AlGrenadine]

Only compared a few models. My initial impression is that the amps sound slightly smoother / less grainy / less grit.

CPU usage is about the same. But I'm only using one amp model in a crowded preset, so any gains in the amp modeling's CPU usage may not be reflected in the total CPU usage.

Not sure it's positive to have less grit/grain...

Thank you!
What does that bold bit mean?
How can we save presets with a footswitch?

Yes. A common request was for a way to save presets with a footswitch. Rather than add an entirely new Function to the Utility category, you can use the good old Amp Level and Save function and just set the level change to "0dB". The need for this feature became enhanced when converting Axe-Fx III presets for the FM9, and there was no reason to not back-port such a simple option to Axe-Fx III and FM3.

Another observation: non-MV amps cranked seem to fluctuate in volume - don't know if it's more accurate according to the newer modeling?

[Bug] Playing a big chord using the FAS Brootalz makes the audio cut out (only fixed by reboot)

Can't reproduce. Special settings?

It is when it is in the name of accuracy. I've seen the traces comparing tube amps to CNFB modeling, zoomed wayyyy in where this matters. It's one of those things where you look at it and ask, "Wait, are there two lines there or one?"

I meant: in a good way. But just a personal initial observation.

no, I also tried re-selecting from the amp selection list - same result

 

[RockYoWorld]

I also recorded before/after the firmware updates. Sounds the same to me

Sure, i'll have to make my own observation tomorrow

Axe-Fx III Firmware Release Notes​

19.00

Version 19.00 firmware represents the first use of the Chase Nonlinear Feedback (CNFB) technique for the solution of nonlinear ODEs. The power amp algorithm has been completely rewritten using the CNFB method. This provides improved accuracy, especially in the clipping and power supply sag behavior vs. frequency.

Added y-axis labels to RTA.

Added Time Shape parameter to Megatap Delay. The EXP/LOG setting is the default and behaves as before allowing time shapes between exponential and logarithmic (including linear). The SIGMOID setting is a four-quadrant shape that allows time shapes between sigmoid and inverse sigmoid. The COSINE and SINE settings select sine wave shapes with the Time Alpha parameter controlling the number of periods from 1 to 8.

FC: Amp Level Save now has an option for 0 dB to allow saving a preset via a footswitch.

Fixed signal level into power amp a bit too high in 6160 models.

Thanks Cliff & FASCo!

Ah I wasn't aware of that available footswitch action, no wonder enhancing it didn't register

Curious to hear the CNFB influence on tube rectifier circuits. Thanks for the kaisen.

 

[la szum]

Wow! Just wow!

 

[Leise]

Bug?
I have some artefacts in every prestet wjen i palmmute an ton rings out.
I use very low noisgate settings.
I went back to 18.03 and the problem was gone.

But sounds great only this issu in palmmutes.

Saved me a few percent CPU on my stereo amp, kitchen sink preset

But would the CPU meter even register efficiency improvements to amps blocks? I thought they ran on their own core, and the CPU meter showed the other core that effects run on. Or has that changed at some point?

Wow, kitchen sink well filled ! Maybe do the dishes ? ;-) Thanks for the comparison, not sure it only comes from the amp block maybe though

Muchas gracias...

The leftmost bar in the RTA is yellow-brown instead of blue. By design?

Turn the wheel there to select which frequency gets the marked by the coulor.

Axe FX III freezes and have to reboot when I switch to a preset with a 5153 amp block, audio goes dead after a click. Also there's all this noise happening when I switch to a preset with the JC-120 amp block.
