About the source code. ---------------------- Should compile using Visual Studio .Net 2003. Test example on how to use it located in "src/samples/bsTestPlayer". It might look a little funny, but was made that way when we wanted to enable other people to use it, without sharing the source... Main synth code is located in "src/isSynth/" Mixer and sequencer effect handling located in "src/isPlayer" GUI code is located directly under "src/" If you want to change, or add, effects isPlayer.cpp and gtk_format.cpp is probably what you want, as a start... Parts of GUI based on a package called "MSDI" - which is a MFC extension library found at codeproject.com, basically a MDI app with only one document. The rest of the code is "(c) Gnilk, Steffo, Zyrax" for their respective parts. // Gnilk
