these vids are amazing, thank you so much 🙏🏽

Thank you! I'm learning a lot with these videos. I don't have a DX7, so I use Dexed to practice. I've learned to program Dexed by reading the user's manual of the DX7...

Hey Elijah, my pleasure! Thanks for watching, I hope my channel makes FM easy for you!

Thank you for a fantastic channel! Do you know if you can control the filter (op2) with the breath controller and the modulation wheel for the LFO separately?

I remember that Bo article as well and felt similarly, but at the time did not think to hook up an oscilloscope, despite my grandfather having several (he had an electronics repair shop). Finding articles like that was such a rush then.

Yeah the Bo Tomlin article and Howard Massey’s Complete DX7 we’re very insightful but the oscilloscope is what changed the game for me. I went from understanding 10% to 90% within a few days. I’m so glad I tried it. I decided to have a look my DX on the scope before putting it up for sale and that’s when I realised how it all worked. This channel would not have existed without that day!

@@madFame It's unfortunate you're "retiring" from doing these tutorials. As I've mentioned before, your clarity in explanation and notation in the DX series videos connects so well with your audience. It's something I struggle to do in my own tutorials in trying to break down the more esoteric and complex FM applications. I know I probably lose a lot of people halfway through, so again I want to compliment you for these !

Hello and thank you for all your explanations concerning the programming of this magnificent synthesizer which is quite complicated to master. Can you tell me if it is possible to simulate a high pass filter with the DX7. I can't. THANKS

Great straightforward video. I am still confused as to how the operator feedback works though? Is there phase delay, some sort of sample averaging to prevent infinite feedback? What does this mean mathematically in terms of harmonics?

@ilyamordvinkin3237

4 жыл бұрын

i'll try to explain but not quite in mathematical terms. for me the fm operator is the function, let it be a sine function. fm operator has an internal phase angle generator, a kind of a diagonal line f(x)=kx. when this line passes through a sine function this will produce, accordingly, a sine wave on output. operator also has input, when you push another operator's signal through it that means you sum this signal with internal phase angle of the operator, that affects the phase angle and this is why signal is changing. when operator is in feedback that means you sum what's inside the operator with something going from the same operator's output at the same time. so, answering to your question: look at the sine wave, it has maximum point, 0 point and minimum point. in 100% feedback you will get a complex wave with max, 0 and min points. what i think is that when sine gets max point the phase angle will rise up to +infinite, when 0 - 0 accordingly, and when minimum - -infinite. P.S. you can also produce a pure white noise with operator. just set multiplier to 0.0 and shift angle to 90° (or 25% in some synths), so it will produce just value, not even a wave, and set feedback to 100%, so you will get the white noise

Thank you! Yes, this series is on-going, and will cover all of the basics including, frequency, envelopes, and other things FM. I'm currently tied up with my next Synth Quest episode which is a mini documentary on the origin of FM and the DX series. It's been a beast to research and edit but I'm almost there. After that, I'll be doing the next episode of FM Explained.

Thx for this! How do these simple patches containing only one modulator and one carrier relate to the more complex algorithms? Do you always come back to these subtractive synth appproximations?

@madFame

3 жыл бұрын

Great question! Complex FM waveforms are quite unusual to most users, so listening to changes in familiar waveforms, like saw and square, helps our ears to track what's happening to the sound. I don't use these waveforms all of the time though, I generally use them when I'm wanting to build a sound quickly. Also, this C+M stack is present in almost every algorithm on any FM system. The MF SAW and MF SQUARE recipes are good for testing the sound and edit process of each FM synth you encounter. Not all FM synths are exactly the same, so whenever I'm on a new FM synth, I program these patches to get my bearings.

What are the numbers next to the boxes, 1.00, 2.00 etc?

But how do you model resonance? That's a key component of what makes subtractive synths interesting.

@madFame

4 жыл бұрын

Excellent question. I've tried to capture the effect of resonance using FM many times but so far haven't found an FM behaviour that emulates it - at least not on the DX7. From what I've learned about waveform behaviour in FM it seems impossible to me. I'd love for someone to prove me wrong though!

@AeDevices

I tried to use a carrier/modulator stack with at least double the value of coarse freq set for the saw stack, while setting the modulator envelope levels in a kind of opposite behaviour. With the right amount of detune you can get a sound that reminds the resonance. Wouldn't say realistic, but definitely a step into the right path for me. I just started to think of resonance as a gritty whistle.

@felixtwomlow4315

​@@madFame I've found that you can get a kind of resonant filter type sound by setting a carrier to a constant frequency (I tend to use 1.000Hz so that the carrier isn't audible without modulation), set the modulator to 1.00 and then adjust the modulator level to get a kind of resonant filter sound. I couldn't say exactly why this works, if I had to guess i'd say that perhaps the dissonance between the carrier and modulator produces a thin band of frequencies that rises in pitch as the modulator output level increases? I basically just copied this method from the FMilters patch on the DX7IID and it seems to work well enough. That said the resonant-esque sound you get from it isn't super pronounced, there are probably ways to enhance it quite substantially with more modulators, different output levels or maybe the inclusion of a feedback loop, I just haven't tried it yet. Hope this helps and you're able to get something out of it if you decide to try.

@@madFame The general, static harmonic behavior of resonant filters on complex waveforms, and especially their dynamic behaviors, are essentially 'incompatible' with FM's Index/Bessel Function behavior of harmonic structures. On an DX7, it's not going to happen -- though as you've undoubtedly found & others have noted is in some very limited or non dynamic situations you can get a 'flavor' of 'resonance'. In AFM of the SY77/99 you can fare much better in static and dynamic resonance emulation using the multiple feedback loops, non-sine waveforms, true 'zero frequency' operator mode and the key parameter of AFM -- Operator phase control. These let you 'cheat the math' to give better emulations of resonance/resonant behaviors. However, as much as AFM does a significantly better resonance emulation, it is still of only limited range and timbre, and still nothing like a classic high resonance 4-Pole ladder filter sweep. On the plus side, you can do true pulse width modulation with AFM.

Very interesting, thank you. But this doesn't really sounds as a filter but rather as a wave morphing. We can see that at the beginning. We see a sine wave mophed to a saw or a square wave.

Thanks for watching! You bring up a good point. Filters remove harmonics within a specified bandwidth. When all sidebands and harmonic frequencies are removed, then you are left with a sine wave. All filters do this, but with analog filters, there is a noticeable drop in volume as well. To emulate this in FM synthesis, you simply apply the same methods in this video to the carrier as well as the modulator.

I wonder if emulating resonant peaks are possible with FM, if so, so should be the formants. I am coming here from Dave Bristow's guide to formants: kzread.info/dash/bejne/l513sKyeg6rKp7Q.html
