can anyone please refer me to some free online resources for these types of synthesis? - i have my head wrapped around subtractive synthesis decently and am looking for new stuff . . .

thx!

i translated it, and the article has nothing to do with FM, Additive, or other forms of synthesis. to be sure, it mentions that such synths are available on pulsar. as i was asking about articles pertaining to using these types of synthesis on pulsar, it follows that i know there are such synths available. . .

and subhuman - what the hell is an "american git"? pardon my ignorance as you are probably laughing at me right now - atleast i can still entertain . . .

so at any rate still looking for good articles - as the "FM One is about senseless to me as far as creating patches goes . . . :sad:

american git is like uhh, i dunno you and me i guess :grin:

anyway, here try this, its pretty good. <a href=http://www.sospubs.co.uk/sos/1997_artic ... html>SLAVE TO THE ALGORITHM
</a> ... And then these two: <a href=http://www.sospubs.co.uk/sos/apr00/arti ... TRODUCTION TO FREQUENCY MODULATION</a>, and <a href=http://www.sospubs.co.uk/sos/may00/arti ... h.htm>MORE on FREQUENCY MODULATION</a>.

If yah need more, ask. Also have a few books around that are rather good...

thx - that should be good for now :grin: - i will read up; i am awaiting the release of the PX-whatever (defex's forthcoming FM-freebie) to do the FM thing. i will muck around in the FM1 a bit though. i thought you were calling me an american git(uarist) which i would object to. i abhore those things (guitars) by and large (exceptions do prove the rule though). :wink:

It's called the Neutron PXR5 and it's pretty cool. Some of the sounds reminded me of the CZ101, I think it's going to be a ringer of a synth. For FM the FM One may be more "complete." Interesting also to know that Yamaha "FM" is in actuality "AM" from what I've been reading...

yeah - i forgot the name - defex told me it is meaningless so i guess it really isn't that important (i asked what it meant when i was beta-testing the synth). i guess the interface is new and some features will be different in v1 - we will see . . .

i had a CZ1000 for awhile, but i sold it cuz i am a newbreed, bred on the the 17" display, and not the three line LCD. when I had a bright light to see the damn thing, and a bit of patience, the Casio could come up with some phat sounds. That was phase-distortion synthesis, which is sorta-like FM, but not the same. Anyways, I sold that old dog when I got the pulsar . . .

Hmm, I am mistaken, its not AM in the Yamaha DX stuff, its PM! Phase Modulation. Check out this <a href=http://www.funet.fi/pub/sci/audio/misc/pm-intro>Article About Yamaha FM</a> and notice the date.

There's a page up about the YM2151+ modular patch on my Modular synth page, which has a short explanation and a few links. The two SOS articles mentioned above are excellent, and this month's SOS has the first in a 2 part 'retro' feature on Yamaha's implementation of FM. Very interesting, but you'll have to buy the magazine as the article won't be online for a few months yet.

For more links to sites where you can find out about synths and synthesis, come over to:

You also asked about Additive synthesis.
The first couple of articles in the synth secrets series from SOS explain this quite nicely.
I can recommend the entire series as an excellent introduction to various synth concepts.

Come to <a href="http:\www.modularsynth.co.uk">www.modularsynth.co.uk</a> - go to the links page and find all the articles referenced at the bottom of the page.

Thx, Ben! great links section, which I had not yet checked out. You continue to be a wonderful asset to the Pulsar Community and I sincerely appreciate your contributions, and find http://www.modularsynth.co.uk to be a great place to hang out (and i have not forgot about the lo-fi drum synth audio sample i promised - it will happen "this month").

The Sound on Sound articles are great. Pricey mag here in the U$A, bet it sure beats Electronic Musician! :razz:

Cheers to the UK! :lol:

Yamaha's fm is something called phase fm, where you modify the phase of the carrier rather than the frequency. It produces a more musical fm sound than pure fm where you modify the frequency which tends to produce more sidebands and subsequently harder to control harmonics. Imagine the carrier is a sine wave and then take the modulator and slide the carrier backwards and forwards based on the modulators amplitude. With classic fm you would be modifying the wavelength instead but with yamaha fm the wavelength remains the same but moves backwards and forwards in time/phase.

AM on the other hand is the same thing a ring modulator does and so is kindof part of the subtractive synthesis vocab (though that's open to debate).
