i guess how the random modes will act, as real random should never produce the same sound at each play ??!
Interestingly enough, this isn't actually true. Real random is the exact opposite: not only should it be capable of producing the same sound, it should be capable of producing the same sound a hundred times in row if you gave it enough chances to do that.
What you're referring to is a "humane" notion of random: it's actually less
random. Think about it like this: say you have a sequence of 5 numbers and you had to guess the next number based on the previous sequence. The previous sequence could be something like 52981. Now, your odds of guessing the next number are 1 to 9 if we assume that the next number could be anything between 1-9 (as it would be if it was truly random). But, if we would limit the randomness so that the sequence would never follow up with a number it had just used, you would know that the next number couldn't be 1 in this sequence: your odds are now 1 to 8, which are better than 1 to 9.
But there's more to this. You see, say you were designing a system that plays back a playlist of songs. Say, you do it for a client. The client would ask "I want it to play them randomly". So you do that. But then the client comes back and says: "Hey, it played the song twice in a row! I don't want that!" and then you have to make it less random: it can't play no longer the same song twice in a row. But even after this, the customer comes back: "Hey, it played one song, then another, but then already played the song before previous song again! I don't want that"
This goes on all the way until you essentially design a system which works something like this: it can't play any of the past 10 songs it has played again (until they are no longer in that pool). But more importantly: it will also go through each song of the playlist before it starts a new cycle. And in fact, the past "10 songs" rule will mostly apply only when the cycle begins anew, as in, it has gone through the whole playlist. The amount of randomness, only to make it please humans, is nearly insignificant in this system.
Of course, I wouldn't know what random means in context of oscillator cycles. As in, how its set up in particular. Humane notion of random probably doesn't matter as much there given how short the cycles are to begin with
