Hi All, I haven't yet looked into this too much, but I was testing some blue features today and using the Pinkston DX7 emulation instrument, the attached CSD causes csound5 (pulled from CVS today) to hang after a few seconds in to compilation. Using an older csound4 compiled on Feb 21 2005, csound renders as expected and does not hang. Not sure if this has to do with reinits or timout or reassigning p3's. Any help on this appreciated! steven
