What is COSM Technology & what's the difference between playing an amp w/ COSM, in contrast to one without it?

I've done a search and I got nothin
I think its just the name for a modeling technology. Roland Cubes use it and I think some multi effects units use it too.
yeah, its Roland's/Boss's digital modelling technology for various things (the amp models on the cubes, the effect and amp models in the Boss GT line, their electronic drum sets too, in Roland's synthesizers....)
Straight from Roland -

Once a musical instrument generates sound vibrations, it reaches the human ear through various mediating objects, each of which significantly affects the sound. The material and configuration of the instrument, the electric/electronic/magnetic amplifying system, the air and the reverberation of the room all affect the final sound. Sound modeling, the latest DSP technology, "virtually" reconstructs these objects. Roland's breakthrough Composite Object Sound Modeling (COSM) uses the advantages of multiple modeling methods and succeeds in accurately emulating existing sounds, as well as producing sounds that have never before been created.

My Korg Toneworks AX3000G has REMS and ESS modeling technology. Whats the difference between COSM and REMS?

Korg is a different company, they have thier own fancy acronyms for their own stuff
Its corporate stuff, they will twist it however they want but basically they're saying that their product have 50+ different amp sounds or processors, and that it blends with the environment and whatnot. Not to say that they're all the same, different sounds are expected from different companies making them, but its actually almost has the same term, this and that technology...

It's corporate branding, yes, but there are differences in the approach each company takes at trying to recreate sounds. There are subtle differences in each approach. The Line 6 approach in the HD500X is different from the Digitech RP5000, which is different from the Zoom G5 approach or the Korg approach or the Roland approach. The processors in these units (pre Sharc-loaded Helix or Sonic Amps Amplifire units), from what I can ascertain, are proprietary, so each company uses different input to recreate sound. I bet the more research and development that goes into creating that processor, the higher the cost per unit. I haven't heard them all, but I know that some amps in the HD500X sound better to my ear than the GT-100, and vice versa. Why that is is down to personal taste and how these companies designed their architecture to recreate sound.
