The opcode Seed effects the results of Linrand, but not of Birnd, and I find this a little strange. My desire was an orchestra whose performance could be repeatable or effected completely by the one Seed value. FYI I am filling ftables with the output of Linrand, then drawing numbers from the tables for various purposes. This is satisfactory, however I have no bipolar form of Linrand, as Birnd is uneffected by Seed. The wonderful generators of Gen21 appear to be unseedable. Would it be desireable to alter Birnd to operate like Linrand, and to be effected by Seed ? I doubt this would not be backward compatible or break existing pieces. Alternatively an option could be added to Linrand to coerce a bipolar output. It would be interesting to hear the thoughts of others. http://www.csounds.com/manual/html/seed.html http://www.csounds.com/manual/html/linrand.html http://www.csounds.com/manual/html/birnd.html Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"
