Freezing file

Hi everybody,   I'm working on different automatic composition projects, involving a lot of random use.   Is it possible to "freeze" a complete score, instead of fixing a seed for each "random generator" (rnd-order function) ?   I'd like to be in a "push button" situation, listening to a lot of versions and saving only the ones really working.   I can do that by saving the score as a pdf and exporting a midifile for each instance, but it would be wonderful
As Stephane also pointed out earlier, if you want to create a number of randomised solutions, but then later want to fix the result to one solution/seed of your choice, one way to do that is to always print the current seed, and in the end to simply replace your randomly generated seed with a seed of your choice.  (progn  (setf seed (random 1000))   (print seed) ;; replace seed below ultimately with seed generating a result you like (init-seed seed)) Best, Torsten
