Global problem with all MIDI Synthesizers

[Yulian]

I think if you really want to use that sound you need to export a bunch of them (as you have already done), choose the one you like best, and then play it back as a sample.

I agree, this is really a proven and working method that will definitely not let you down!
Only this desire to automate everything, control each parameter and, if necessary, immediately modify it does not give rest)
Perhaps there are synthesizers in which triggering a waveform start with each note played.
But still, let the music be a priority!)

This is a superb attitude I wish more of us shared! We used to do so much with so little because we needed to find a solution, even if it involved a few more steps.

This is a good general rule I think. With any synthesiser there are so many moving parts from oscillator phase to lfos and delays and filter sweeps. Once it's rendered it's locked in, like a photo of a tree in the wind.

yeah i can replicate this with 4osc too. If you render the the track you can see slight differences in the waveform on each beat - in particular in regards to the peaks of the sine wave and how they align with the beat. However, there is an explanation - analog style synths usually have free running oscillators that are simply attenuated at the VCA stage (ie. with the ADSR envelope). if you generate an arbitrary frequency sine wave - one that doesn't sync perfectly with your tempo (eg. C1 ) - then you will get slightly different parts of the sine wave attenuated each beat.
At higher frequencies i don't think this would ever be noticeable, but think it likely is at low pitches, and short envelopes where the "error" is a bigger percentage of the envelope duration.
Different synths may have options to allow you to "restart" the oscillator on note trigger. (or as other have suggested, you could render and use in a sampler)

Thank you very much for explaining to me how it works and what is the reason for this behavior of the waveform, I did not know about it!

Maybe you could recommend some of these synths? Preferably among the free ones)) Or any, so that I can look for free analogues.
