I use regurlarly ableton analog, NI Massive and FAW Circle, whith which I can produice more or less any sound i like, but I can get, at all, how synthesis works and how to make a sound with it.

Do a Google search and you can find many references on Frequency Modulation (FM) synthesis and how to use it, compared to subtractive synthesis, additive synthesis, and other types.

Crude analog frequency modulation synthesis was a feature of some early analog subtractive synthesizers. However, a powerful form of FM synthesis in a digital implementation became extremely popular in the early 1980s with the release of the Yamaha DX7 family of synthesizers. There was a lot published on FM synthesis around that time.

It should be noted that the Minimoog is a subtractive synthesizer, as are the vast majority of analog and VA synths. I'm also not sure you have the routing options necessary to achieve any sort of FM on the Mini. Maybe the modular? – Tim Lehner Mar 19 at 12:42

Thank you for correcting my "typo". I meant to say "subtractive". But the Minimoog could indeed do frequency modulation synthesis on oscillator 3. Here is proof in a video. youtu.be/CzpgTOAF-qU – Wheat Williams Mar 19 at 15:29
@WheatWilliams: The digital FM synthesis used in the DX series was very different from analog FM synthesis. Among other things, the internal sampling rates were insufficient to prevent significant aliasing of some frequency components in the generated signals, and such aliasing ends up playing a significant role in the sound of many patches. Were one to construct an analog equivalent of what the DX is 'supposed' to be doing, its sound would be very different from that of the DX. [note: my experience is with my DX21, but I expect the DX7 is similar in that regard]. – supercat Mar 19 at 15:59
Of course you are right, supercat. I said that the FM synthesis on the Minimoog was crude and the FM synthesis on the DX7 was very sophisticated, and that one was analog and one was digital. I'm well aware that early Yamaha FM synthesizers were essentially 10 or 12 bit and very noisy. I had a TX81Z back then. I said nothing to make anybody think that the Minimoog and the DX7 would be equivalent or that they could make similar sounds. I just said that they were both examples of FM synthesis, which is perfectly true. – Wheat Williams Mar 19 at 21:54
@WheatWilliams: My point isn't that the Yamaha does FM synthesis better, but rather that because of digital aliasing effects it is totally unlike anything in the analog world, crude or otherwise. Incidentally, I wonder if the people who designed the DX7 ever played any arcade machines designed by Eugene Jarvis or featuring his sound board (Defender, e.g. debuted in 1979). The Jarvis sound board uses a 6800 microprocessor to generate waveforms by periodically adding various registers to other registers in a fashion conceptually similar to the Yamaha DX series. – supercat Mar 20 at 16:38
