I know it, because I am the greatest authority on this and every subject.
Thank you.

Seriously though...it's really good.


For the highest quality string sound, Kaivo is better... but obviously not nearly as flexible and it does not have the fantastic morphing of Sculpture.

I'll have to check that out. I'll check the demo I just dl'ed out after work today.
I have the AAS String studio v2 and it's excellent.

String Studio is one of my favorites... It is also quite flexible

There is something beautifully natural sounding about Kaivo. It is a pleasure to play. Somehow little note bends sound more 'right'. I think they are using a more sophisticated modeling (it shows in the CPU use).

You can make various pad type sounds using the granulator, but I have so far not found that particularly compelling... but the string sounds and some percussive sounds are superb.

Arturia just did a great job modeling Hohner Clavinet.

All of the piano stuff is pretty cool if we stopped being snobby about perfection, I just wish theyd thrown In a few non piano parameters to tweak so we could take it further away from the boring piano sound.
I personally dislike the sound of piano generally, real or otherwise

Sounds good enough for a clavinet, but I think most of the e-piano sounds need a little tweaking. I know the clav is different to the e-pianos, but they could all do with some small improvements - even if it is at the cost of more CPU resources.

On the other hand, there really is no such thing as a 100% perfectly physically modeled VI...but we are getting so tantalizingly close.

Looks promising. Oh, I see this was posted earlier. Sorry...

"Derailer is a physical modelling system with two basic elements. One is a metal bar that you can strike or bow. The other is a nonlinear mass/spring connection. This allows you to join two bars together so that vibrations from one create sympathetic resonance in the other. By connecting multiple bars you can create new instruments that have their own unique sound.

"There are 37 strike bars, 5 resonators, and up to 81 connections to play with. The adjustable physical parameters and nonlinearity of the connections produce a wide range of tonal variation that reacts to striking velocity or bowing pressure. Derailer uses finite-difference time-domain numerical modelling."

AudioModeling Technologies (Sample / Physical Modeling)

SWT - Synchronous Waves Triggering:
- Saxophones on Kontakt (SaxBrothers)

SWAM - Synchronous Waves Acoustic Modeling
- SWAM v1: Reeds
- SWAM v2: Flutes
- SWAM S: Bowed Strings

The technology used in our instruments is indeed a combination of different techniques.
I started in 2007 with a technology called SWT - Synchronous Waves Triggering (a MultiVector Samples ReSynthesis) which was my first attempt to model samples in realtime. These instruments (SaxBrothers) were developed on Native Instrument Kontakt platform. Kontakt (that is a very good platform and basically an advanced sampler perfect for sample libraries) is non the best tool for this Synthesis technique, so I decided to make a proprietary engine. In 2009 I met Emanuele Parravicini and together begun the development of the SWAM engine.
SWAM, Synchronous Waves Acoustic Modeling (or now we prefer Synchronous Waves Audio Modeling) adds concepts of Physical Modeling to the MultiVector Sample technique. We made different versions of the engine, each one more suitable for a specific family of instruments.
Each version has different balance between Sample and Physical Modeling.
Reeds, that use engine version 1, is basically a Multivector Sample engine with some Physical Modeled Resonance elements and Behavioral modeling techniques.
Flutes use version 2 with a bigger component of physical modeling tecnique than sampling and in our opinion represent the best example of mixing between both techniques because we have sampled the lower dynamics on the first octave only and all other notes and dynamics are obtained by modeling this limited sampled material, through the obtainment of Overtones.
Lastly, Bowed Strings (our recent product) are made mainly with Physical Modeling approach. We decided to 100% model Bowed Strings by WaveGuide Synthesis (a Physical Modeling method conceived by Prof. Julius O.Smith) because it was very difficult obtain the BowPressure parameter (Very important expression control) with others SWAM techniques.

Thanks a lot for the enlightment, much appreciated !

...can you perhaps, (without betraying some proprietary top secrets 8) ) , explain this concept of multivector sample technique ?

I'm finding Chromaphone to be much more capable than first appears, got a really lovely woody upright bass with it last night, plus a sort of koto/banjo ish sound with a scraped release. It's far more than just a percussion synth.

Chromaphone is lovely sounding and pretty flexible. I do wish it had more modulation options... but that's the I want to push things to the limits part of me :)

It's (from my limited understanding) basically phase-aligned samples that can be crossfaded in multiple dimensions (not just from A to B, but from somewhere between A and B you can then crossfade to C, and then all that to D, or something like that).

Roland also coins the term ' behavioral modelling technology ' for their supernatural acoustic engine , integra range etc.
All I can say is that in some supernatural acoustic instruments , the BMT it's just a fancy word for advanced layering of samples and midi triggering of said sample layers .


Not saying you're lying , I am just cautious when this kindof terminology is used .
