Now that explains things

I lijked this video very much, but now Iâm confused. I heard a number of times that Yamaha doesnât use FM-synthesis but it uses phase-modulation. Does anybody know what is really going on?
Hereâs a good explanation of that from Jakub Ciupinski on youtube

Yes, thank you, I know this video and it perfectly illustrates the confusion. But if Yamaha indeed uses phase-modulation, why are they once again associated with John Chowning in the video above?
The one and only Alan Parsons, in good hands with Rick Beato:
Apart from being famous for the stellar sound of Dark Side Of The Moon, the Alan Parsons Project records are a study in recording perfection, and especially the earlier ones, of musical joy, innovation and creativity. Great stuff!
Iâll just leave this here at the endâŚ

This video is generally interesting, most of it is unremarkable if you have been working with synths and audio for awhile, but this specific part that really got me is where the audio that is playing is constant but I literally hear it differently depending on which side of the video I am looking at bear / fair !!!

Software development wisdom. Iâm a recent convert to test-driven development, and this guy has a lot of interesting things to say on TDD and continuous integration. Here he summarizes 40 years of experience in a single video.
Thereâs also this thing I wrote a few years ago about FM vs. PM. Demo/docs/fm.md at main ¡ squinkylabs/Demo ¡ GitHub
My guess is that even thought Yamaha used mostly PM, that itâs covered by the same patent? Itâs PM and FM are pretty much the same thing?
In any case they sound very much alike. A funny thing is that when Casio introduced their pm-synthesizers, it was found remarkable that they sounded exactly like Yamahaâs fm-synths.
Werenât the Casios phase distortion? That is different from FM.
With this discussion of PM and FM, some may be interested in the latest Mylar Melodies podcast where Alex talks to Matthew Allum. Both of them are real connoisseurs of FM synths, and know the different Yamahas, but Matthew is, of course, the creator the great Akemieâs Castle, which has ruled the roost of 4 operator Eurorack FM until recently, with RYKâs Vector Wave and Algo. Matthew is also the creator of the recent highly rated Cizzle module, Casio-based PD.

Yes, you are right. Itâs just that I donât fully understand the difference. By the way, that is a very impressive and useful set of documentation that you have there.
If you read the manual for either of the phase distortion modules in VCV, (ALM Cizzle or Warp Core) they both explain it very well. Basically, you digitise a sine wave into a set of values, and if you read those values back at a linear rate, it reproduces the original waveform. The phase distortion part refers to distorting the phase of the lookup, which produces new waveforms. Phase modulation is just changing the phase of an oscillator at audio rate, instead of the frequency which somehow ends up sounding the same. Iâve forgotten how that works, need to read Squinkyâs paper again!

yeah, that sounds right. And I will say for the 100th time that âphase distortionâ has really nothing to do with FM. Itâs âjustâ waveshaping.
