See the wish list
this is a legit list of both hardware and software items.Off the top of my head I can think of several Ax4 items. In no particular order:
(There's a thread for this list somewhere (Ax4 feature list) but I can't seem to find it.)
- Relay switching jacks to facilitate amp channel switching in 4cm scenarios.
- Separated Left/Right Input and Output blocks.
- Stereo block input option for all pitch modes (several only allow mono in the current Axefx).
- Acoustic sim block including 12 String mode.
- Feedbacker block equal or better than digitech Freqout.
- Doubler block equal or better than TC mimic.
- A Tape/Doubler block equal or better than Strymon Deco.
- Increased CPU (yes - some can max it in some scenarios (and always will)).
- Full user assignable CPU without block instance limits within available CPU.
- Allow distinct modifiers attached to a given control in each and every channel.
- Isolated virtual power amp section capability.
- Reverse MUX block that can send input to a selectable mix of multiple output paths.
- More Send/Return blocks.
- Profiling capability (have not always been a fan, but Tonex convinces me it is at least .. "handy".
- Export Tone Match to PEQ.
- 31 Band Output EQs - on/off midi switchable.
- Offline Patch Editing.
- Ios editor support.
- Separate headphone volume ctrl.
- Customizable front panel home screen.
- 2U Form factor.
- Merged Midi Out/Thru option.
- Polyphonic synth
- ...
the only improvement id like is enough processing power that i dont have to worry about resource utilization...and a 2nd pitch block.There’s been a lot of talk about what Fractal’s next gen product will be, but I don’t really understand what could be added to the AxeIV, FM3, and FM9 next-gen that isn’t already on those units now. The only thing I can think of is capturing, but that’s not really Fractal’s cup of tea. I do wish tone match was added to the FM3 and FM9, but I don’t think that will ever happen.

Even just the option to load some for a select few mics would be huge. Like I don’t need all 23 mics from the 810 ampeg pack, but loading 3-4 favorites would be nice.Enough memory to have full dynacabs on board would be great, lack of it is why i don't buy them. That A LOT of memory though.

But here's the thing - I'm pretty certain that Cliff doesn't agree with that.Yeah, I just think that the modeling itself is as good as it can possibly get.
