Hi List, I'm wondering why I keep repeatedly getting "Segmentation Violation" thrown by Csound when running the ReznikScanPiece.csd file from the OLPC wiki? It happens when running to .wav or in real-time. Is there something about this orchestra?? I was going to supply the "voice.wav" in this email using csb64enc but then it would be too large... for the supporting files (ie. scan matrices & audio files) see http://wiki.laptop.org/go/Csound:Csound_Editor Thanks for your help, -David Csound flags used during segmentation violation are: -odac -d -m0 -b2048 -B4096 -+rtaudio=mme ; real time -oReznikScanPiece.wav -W -K -R -d ; offline Csound version 5.08 (double samples) libsndfile-1.0.17 System info: Host Name: PRECISION690 OS Name: Microsoftr Windows VistaT Ultimate OS Version: 6.0.6000 N/A Build 6000 OS Manufacturer: Microsoft Corporation OS Configuration: Standalone Workstation OS Build Type: Multiprocessor Free System Manufacturer: Dell Inc.
