Here's an example usage: in one command line: C:\Documents and Settings\Graham>chuck --loop [chuck](VM): sporking incoming shred: 1 (scale.ck)... [chuck](VM): sporking incoming shred: 2 (pop1_fm1.ck)... [chuck](VM): replacing shred 2 (pop1_fm1.ck) with 2 (pop1_fm1.ck)... <vm stops> in another one: C:\Documents and Settings\Graham\My Documents\chuck>chuck + scale.ck sessions\po p1\pop1_fm1.ck [chuck(remote)]: operation successful C:\Documents and Settings\Graham\My Documents\chuck>chuck = 2 sessions\pop1\pop1 _fm1.ck [chuck(remote)]: operation successful The sound begins to skip, and we get an error dialog: "chuck.exe has encountered a problem and needs to close. We are sorry for the inconvenience." If you debug the process in Visual Studio, you get: Unhandled exception at 0x0041117c in chuck.exe: 0xC0000005: Access violation reading location 0x00000000. Strangely, replacement works great with the Audicle. Which is a joy to use! best, Graham PS Is there a way to search the list archives? I want to make sure I'm not double posting previous issues.
