Hi Dr. B, I'm not sure about what is necessary to make this a backup for MIDI input and suspect it's not as easy as it sounds due to the way csound loads up external plugins and the order in which everything is being done. It might require adding the keyboard into the core library but might be a way around that using global signals and storing a reference to the midi pointer there (so csound loads, the FLTK module inits and adds a function pointer to the global space, csound tries to open the given midi device, then if fails, looks to see if that function pointer for the fltk keyboard exists and use that if available). I'm really concerned about the CPU spike though as well as solidifying the keyboard first; the part to make it a default backup is a lot to think about right now so will look at that next. steven On 10/27/06, Dr. Richard Boulanger wrote: > I agree that it would be wonderful to play the keyboard from the > ascii keyboard as well. > > -dB > > Also, while you are at it.
