Long ago, in the infancy of the DX7, I rented one for a week ahead of a recording, having only very basic experience of a 2 oscillator analogue instrument. I remember it was a huge adventure working on sounds by ear, understanding very little of the synthesis by algorithm. The studio engineer was astounded that I'd managed to find what I wanted. In ten minutes you have taught me how to understand the basic requirements of using fm algorithms creatively. Amazing and touching to see a DX7 in use after almost 40 years😱

He's not wrong. This is the best video on this topic.

Also watching to better understand the sound capabilities of the Yamaha YM2612 inside the Megadrive! FM synth is interesting and both simple and complicated. I'm amazed by those who can create almost all kind of sounds with FM.

I'm trying to learn how Kurzweil does their FM Synthesis (it's more organic, but also, more problematic because of that.) All the basics keep pointing back to Yamaha and the DX7. Kudos for using the oscilloscope! I hope you keep doing some more basic breakdowns as to how the operators work with each other. The Kurzweil lacks the ability to have feedback oscillators, but something tells me that this isn't a dealbreaker.

Spectacular. I know nothing about FM synthesis, this video explained things from scratch clearly and quickly.

Thanks for the video. My synthesis teacher showed me this and linked it in his blog. I'm currently learning about FM synthesis. I think it's become quite popular in dance music again these days. But I think not that many people have the time or the patience to program something like a DX7. Most people don't stray far beyond the realm of a simple FM bass tone so it's nice to see your videos.

It's a shame you don't have access to a time machine. You could have made yourself a small fortune through your FM/DX knowledge and skills in the 80's. Unless....you've spent the last 30 years understanding how FM works? I owned a DX100 and literally half my small town tried to get their head around it without much success and plenty of head scratching, swearing and mumbling. I steered well clear of anything FM until I bought a Digitone last year. Which I'm still a long way from mastering, but your videos are the clearest explanations I've found so far.

I'm still trying to fully understand FM synthesis and programming the DX7, so I might be getting something wrong here. Is the statement around 1:40 correct, saying the modulators increase or decrease the sine wave's output level? I thought modulators modulate the frequency or phase of another operator, not its amplitude.

@madFame

Жыл бұрын

Every operator produces a sine wave and has an adjustable output level. The effect of Output level is determined by the function of the operator. If an operator is a modulator, increasing its output level affects the strength or amount that it modulates the next operator its connected to (modulation). If an operator is a carrier, changing its output level affects the volume of the sound that's produced (amplitude).

Or wait. Maybe I could mod mine with a tiny oscilloscope like in the monologue?? I love it though.

I notice when I look at the DX-7 algorithms that there is a minimum of two operators, I guess there is no such thing as a 6 op stack? Or a 5 op stack with a carrier on the side?

@madFame

6 жыл бұрын

Hi there. technically there can be any combination of algorithms but the ones we see on many FM synths have been auditioned by the engineers and designers as the most useful algorithms for a wide variety of possibilities. In most cases the ideal number of operators is 3 or 4 as this allows maximum tonal variety. Any more than that only produces distortion and noise which can be achieved with 2 ops and a feedback loop anyway.

This is an excellent video thank you. I just decided to put my head into FM and so after getting Komplete 13 I decided to give FM8 a spin. My question is on the DX7 algorithm no. 4 I noticed 4 and 6 are joined in a feedback loop. Does this mean 4,5 and 6 are joined in that loop or just 4 and 6.

In FM synthesis, the modulators output level determines how much its waveform (sine) distorts and modulates the operator below it. It doesn't affect a parameter, it changes the waveform shape of the operator below it. In this case a sine wave is distorted to another complex waveform. This is true if a modulator is connected to another modulator or carrier in an algorithm.

@paul_arutyunov In FM synthesis, frequency modulation is achieved by increasing a modulators output level into another operator (carrier). Changing the frequency settings (Coarse and Fine) will change the spectral range but it's effects won't be present if the output level is less than 50. The active output level range (in a DX synth) generally occurs between 50 and 99.

@Oskar Terlecki - Really good question! If you really love FM sounds and want a classic synth for a good second-hand price, then I would say yes, get a DX7. My videos will help you learn how to program it too. However, the DX7 won't do a lot of the classic subtractive synth sounds like you get from Moog, Oberheim, Sequential Circuits, etc. So if you want those sounds then don't get a DX7. My first synth was a Korg MS2000. I think this is the best beginner synth ever. If you want a mix of Subtractive, Samples, AND FM synthesis then definitely get a Yamaha MODX.

I can! :) Ok, so an operator is like a control box that has several functions. The main function is producing a sine wave. From here it has other functions to control that sine wave, such as output level, frequency, envelope etc. If you look at the "algorithm type" diagram in my video at 3:07 all of those boxes are operators. The orange operators are Carriers, the blue operators are Modulators. An operator can only be one of these at any one time and this is determined by the algorithm you select. A heavily simplified explanation of this is: Operators in the Carrier position affect volume changes in the sound you're making. Operators in the Modulator position affect the frequency of the waveform shape you're programming.

I just watched your video, it's pretty well done! Looking forward to see all of them. Just here your explanation is not quite exact - operators in modulator job affect frequency, and can be used for vibrato (low frequency modulation), but when modulating frequency enters audio range, it affects timbre.

Great video! The one thing I regret not seeing in videos is the math behind , I believe it could bring some more sense to those algorithms . I had a go at making a software fm synth with a Dspic controller, I ended up with a very simplified form for the algo at 1:53 : Out(t)=AdsrGain1*sin(2*PI*f1*t+AdsrGain2/ModGain*sin(2*PI*f2*t)) Assuming no phase shift between carrier and modulator, sine waves only, and *no feedback*. Anybody else have a go? Thanks for your tutorial :)

Thanks for watching! Music, sound and their relationship with mathematics is a fascinating subject. Although my videos demonstrate musical applications of FM synthesis using the DX7, it would be beneficial if someone made a video/series explaining the mathematical nature of FM. Someone should do a full series with John Chowning and David Bristow! Which reminds me, they both wrote a book together called FM Theory & Applications - By Musicians for Musicians. It has some explanation of the mathematical side of FM, although it is simplified. Definitely worth reading if you haven't already.

Is the sy77 superior to the dx7

Yes, it's much more capable.

oh yes..in so many ways.realistic acoustic sounds + pure FM with so much more complex algos and routing and feedback options and you can even change shape of feedback and resonance like analog + effects if you need and 8 individual outs.

Where did you suddenly get the sawtooth from? This synth has no pulse nor sawtooth oscillators.

Yeah I agree, although it took me a while to figure out the DX7, once it all fell into place I understood how massive it's potential was. I was surprised how easy the FM synthesis method actually was once I had just a couple of basics sorted out and I gladly let go of wanting it to sound like a subtractive synth too. Hopefully these videos help other users get up and running sooner than it took me. Thanks for watching!
