    Newly reworked drive models utilizing SPICE engineering concepts to improve the drives in the AXEFXIII.

    3.02

    Improved Drive block. WARNING!!! The sound of some of the drive models may have changed significantly.

    · Drive models based on op-amp and diode clipping topologies have been completely overhauled.

    · For many types there is now a “Dry Gain” control. This parameter controls the amount of “dry” signal mixed with the “wet” (distorted) signal. For a Tube Screamer-based model this will default to 100% due to the topology. For other types this will default to 0. Values up to 200% are allowed. Note that the dry data is added before any tone controls and therefore is not exactly equivalent to a mix but rather replicates the behavior of analog circuits.

    · Drive types based on op-amp and diode clipping circuits now allow control over the type and quantity of diodes in the positive and negative polarity. For example, the user can select (2) 1N34A diodes for positive signal polarity and (1) red LED for negative. Experiment with the various diode types and quantities to obtain new and unique sounds.

    · The Basic GUI page now reflects only the controls found on the actual pedal. In cases where the actual pedal does not have any tone controls a simple Tone control is included for convenience.

    Added “All” to Tuner Input Source selection. This sums all inputs.

    Fixed Tone Match block not updating correctly between preset changes if different Mode used.

    The diode selection feature is an incredible tool. @cliffc8488 knocking it right out of the park again!

    That wet/dry control for all drives sounds awesome! How can something be 200% if it’s a blend though?

    I'm super excited for the Axe-Edit update so I can really get my hands dirty with this.

    More incredible updates from Fractal Audio on their monster powerhouse pre-amp and fx processor. Kickbutt!

    What now? The drive update just came out yesterday and there’s another one today? Man that’s some major dedication right there!!

    Really interesting! I'm one who found the drive effects to be underwhelming in the Fractal. I wonder if this will trickle down to the AX8 at all?

    Drives are killer; more added, many refined ... unbeatable!

    Yup; constant improvement - ya’ll know how Cliff/FAS roll - fast and awesome. Multiple betas with the production final just dropping!

    Lots of goodness to love!

    Oh, and for those who want simplified/basic controls “just like real life amp” ... they’re there too now as an option for the amp block. No more “it’s too complex” arguments.

    Now I just need an Axe Fx 3 to actually become available somewhere. :D

    There's always been a Mix control.

    But the new Dry Level control (separate from Mix) lets you determine how much dry signal will "leak" through the virtual diodes. 200% means that you can make it two times as much as the measured amount in that virtual diode.

    The amount of regular updates and improvements are incredible. I've got to get a III later this year. It just has to be done.

    This is an incredibly impressive feature. I've looked into real-time spice emulations before and there hasn't really been a robust system available. The fact that fractal have built one in house is nothing short of crazy. Incredible engineering going on and they have my deepest respect for pushing the boundaries of what is considered possible. I might have to upgrade from my Axe II now :)

    The clean mix feature is also really cool, it's something I often add onto my DIY hardware pedals. Glad to see I could now replicate that on the Fractal.

    Cliff had this to say about the real-time simulation with respect to drives:

    It normally takes a lot of CPU power to do a real-time simulation. The amp block uses an entire dedicated DSP. To do even a simple distortion pedal would normally require huge amounts of CPU. But I stumbled upon a simple trick that reduces it dramatically.

    This algorithm applies to a particular set of circuits that incorporate diodes as a nonlinear component. SPICE modeling is particularly slow when modeling diodes due to convergence issues. However the diodes in drive pedals are used in such a way that there's a trick that can be employed to dramatically decrease the amount of CPU needed to simulate the circuit.

    The drives sound awesome now
    They really are pushing the quality across board
    The fact that in March they are shooting some far field irs to try some ideas Cliff has is super cool
    Imagine if you could blend the close micd and far field
    To get the pefect balence if amp in the room

    Already asked about this a while ago and it won't

    Ya, all these updates makes the older stuff kind of obsolete now. Better sounding amps, better drives, possible better sounding cabs. Love digital but this is the part that bites, always something new coming out that's bigger and better.

    Dude, it's the same way with tube amps and pedals. At least with this, if something new IS created, a lot of the time we get it as an update.

    If a better fuzz pedal comes out? 200+ dollars. If a superior JTM-45 clone comes out? 2000+ dollars.

    Nothing about digital is worse in that regard, really.

    Hell, if an amp builder comes out with some changes to an amp you already bought from them, a vast majority of the time you are paying for shipping and an upgrade fee of, at least a couple hundred bucks.
