Fractal says the AM-4 has the same amp and cab models as the Axe FX-3. Plus a "curated" set of effects and drives from the product line. The VP-4 already covers most of the drives and effects found in the Axe FX-3. But it has no amp or cab modeling.

Having looked at the owner's manual, it looks like the AM-4 paired with a VP-4 will be a real power house. The two units connect digitally via S/PDIF and MIDI to act in multiple ways as if they were one unit.

AM-4 is exactly the same size and form factor as the VP-4 effects modeler. In fact, they look exactly the same from the top, with the same screen, knobs and buttons. The AM-4 has more back panel I/O than the VP-4. The limited analog I/O on VP-4 was a serious limitation when connecting VP-4 in a 4CM setup. There was no way to do a mono path in front of your amp and stereo effects after it in a WDW configuration.

Combing both however will solve this problem. Plus you double the blocks, switches and knobs and both units work together.

Ron, if I am interpreting the AM-4 description correctly, the AM-4 and VP-4 use the same block architecture and the editors can work for both units. So since you are working on full support of the VP-4 already, could you potentially get full support working on the AM-4 as well?
 
This is the first I've heard of this product, but if it appears to be the same hardware, then I would guess that it has the same MIDI firmware as well. That would make it relatively easy. I'm still waiting on some clarifications from Fractal on the VP4, I'll ask them about this new one when I talk to them next.
 
Just for the record, I saw a post from Leon Todd who is an official Fractal reviewer, where he says that the AM-4 actually has a somewhat more powerful DSP than VP-4 so it can run the amp / cab blocks. That said, the MIDI implementation is likely to be similar, if not identical. Hope this is any easy port for RJM!
 
It's not going to be for a few weeks, at least. And, it'll probably be basic support, like we have for the VP4. There are still some things we need to work out with Fractal regarding communication.
