I had a Sony portable CD player (E33 maybe?) like that: for any given total number of tracks it would always use the same shuffle order. I noticed when I was playing through a CD series whose songs were parceled out twelve to each disc; every disc I played in shuffle mode picked up its tracks in the same sequence as every othe twelve-track disc. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
Re: MD: Shuffle on G750
well, 1,3,7,15,31 is (2^n)-1, though the rest of the pattern seems irregular. any ideas? Sounds something like a shift-register (with XOR taps) pseudo-random generator. They always generate the same sequence, which never contains zero. (Zero would cause the sequence to get "stuck".) The maximum length of the sequence (given proper tap selection) is 2^n - 1, where "n" is the length in bits of the shift register. The key to using this type of sequence is to have a long sequence (16 or even 32 bits) and to use a function of some variable, like time/date or length of a key-press, to determine the starting position. When properly designed, this type of sequence generator always produces a sequence 2^n -1 long, which would probably not corespond to the number of tracks on the disc, so it could be used to "shuffle" the order in an array that contained a number of unique elements corresponding to the number of tracks. With proper precautions, this type of "shuffle" could generate many unique non-repeating sequences, regardless of the number of tracks. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

Re: MD: Shuffle on G750
I think it's pretty amazing that you picked up on that sequence...
