Hello! I am using csound "Csound version 5.09" provided by the rpm for openSuSE. I will give here a minimal example in order to demonstrate a problem that I encountered. Have a look at the file at the end of this message. It creates 4 random notes. Having set "seed 0" I get once a result, that I consider interesting. Csound gives in the output info Seeding from current time 1061022902 So next time I set "seed 1061022902" in order to keep this trajectory. But I get a different one as Csound outputs Seeding with 1061022912 What am I understanding incorrectly? How could I set the seed at the desired value (the one that gave me a satisfactory result when seed was set to 0)? Thanks for any help Alexandros ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; -d -o seed.wav sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 instr 1 seed 0 igrain = 1 start: timout 0, igrain, continue reinit start continue: irand unirand 12 inote = floor(irand) kenv linseg 0, igrain/2, 1, igrain/2, 0 a1 oscil kenv*20000, cpsoct(8+inote/12), 1 out a1 endin f1 0 8192 10 1 i1 0 4 e
