synthesizer modeling

2002-10-27 by spaceanimals

I understand that the AN1X uses physical modeling for most of its 
synth functions. What synth did they use for the model? I got a 
chance to hear Reason, a software synth. The filters on it sound very 
realistic, as do the AN1X but different.

When they talk of "physical modeling," they mean it in a different sense: mathematical modeling.  Everything that happens in nature -- movement, sound, electron flow -- follows basic laws of physics, and can be described (or very nearly so) by a mathematical formula, plus a set of initial conditions; i.e., the way the item was held, pushed,etc. when the event started.

When I was in engineering college we studied what makes a guitar string vibrate.  Using fairly complex math, you can accurately predict how a real string vibrates on a guitar, even predicting things like the sound's increase in high harmonics as one presses closer to the bridge.  This process is called 'mathematical modeling,' and is often used to study events that happen in nature, but are difficult to witness.

Once the mathematical model for a guitar string, a saxophone reed, or an analog circuit is known, all that is required to simulate that instrument is a computer with enough processing power to solve the math in real time -- or a set of digital logic that is tuned to solving a few specific mathematical problems at high speed.  The first example is what computer programs like Native Instruments' Pro-52 and B-4 use; the second example is what dedicated physical modeling synths are.  In fact, analog synths are easier to model than acoustic instruments like pianos and clarinets, because their waveforms are fairly simple and repeatable.

This is not to say that the AN1x wasn't modeled (in the sense of "copied") after some of the classic analog synthesizers of the 70's and 80's.  It seems to be a mix of Moog, ARP, and Roland features, with maybe a little Sequential Circuits thrown in.  The basic architecture is very Jupiter-line, IMHO.

I like Bruce's take on the sounds but it would be really fun to hear from
someone who actually designed the synth.  I was crying for years on the Midi
Guitar list trying to find a bi-lingual engineer type who could translate
some Japanese... and one gentleman finally popped up.  I'll ask him if he
can find the 411 from Yammamahahaha themselves.

I had the review from Keyboard back in '97 and they didn't mention anything
I recall about the design parameters - for that matter, none of the VA
synths discussed had any info on the modeling parameters.

I allways thought they used the prophet as a 'template' for the an1x...never heard a real prophet so I couldn't really tell you if it sounds anyting alike.

RE: [AN1x] synthesizer modeling

2002-10-28 by Chada, Jaish

I always thought the AN1x filter algorithms were modelled after the Prophet
5. Didn't Yamaha buy Sequential off Korg? It just rings a bell from the
Prophet VS and Yamaha's Vector synth line...like the SY22 from a couple of
years, prior?

RE: [AN1x] synthesizer modeling

2002-10-28 by Chada, Jaish

From my previous post, I think Ed (bastiaan) is right. The Nord Lead DID
have a lot of Prophet 5 patches, and Clavia were one of (or THE) first to
produce a VIRTUAL Analogue synth. SO, since most companies jumped on to
start a trend, it makes sense that Yamaha, rather than outright copying the
Nord Lead, would have said, "Hey we know Sequential's Secrets and can do a
better job of a Prophet 5 emulation or any other analogue for that matter"
and produced the AN1x. Well, that's my conspiracy theory.

AFAIK does the AN1x models the Prophet 5, just like the NordLead 1/2 
does. That explains that they sound so nice together...;)

Re: [AN1x] synthesizer modeling

2002-10-30 by Mark Pipher

It's definitely fact, not theory. Take a read through this page from
Yamaha's XGfactory website, regarding the PLG150AN card:

http://www.xgfactory.com/html/plg/p150anx.htm

Here are a few quotes that sum it up for everyone and put this to rest:

"PLG150-ANX - The closest thing to a Sequential Circuits Prophet 5 you will
ever hear from modeling synthesis is now available as a PLG board for your
SW1000XG."

"There was always something about the Prophet 5 that made it sound
wonderful. Maybe it was the filters, maybe the oscillators, and maybe the
overall design. Whatever it was, it inspired Yamaha to develop the
PLG150ANX, based around our acclaimed AN1x synth technology, but revoiced
and re-tweaked to give you as close as we can get to the original sound of
what many people call the best analogue synth ever made."

Settled? :)

Re: [AN1x] synthesizer modeling

2002-10-30 by Jerry Aiyathurai

This is interesting reading. I guess there's two questions. To what 
degree was Yamaha modelling the Prophet 5? How well does the AN model 
emulate the Prophet?

I had read this article before and reasoned that the addition of 
oscillator cross-mod to the AN plugin card was to give it more 
prophet-like features. Still, audio rate modulation of the filter and 
pulsewidth are not available on any of the AN models. Nor is the 
ability to use noise as a modulation source (I think). These are 
Prophet trademarks and one would think that a faithful model would 
attempt such features.

If Yamaha modelled the Prophet, they did an incomplete job. However, 
if the AN model is merely Prophet influenced, it's a pretty complete 
synthesizer.

Cheers,

Jerry
