SmartString

Basic Idea:

Based on the plukmain project in C++, or the Example Karplus.ck and/or Mandolin.ck programs, modify the code to do more intelligent things based on the scorefile input, and to do more intelligent things based on the nature of the optional soundfile input. Examples below. You might have better ideas (of course), but make sure you do some real work to improve the instrument, and don't just break it in funny ways (break it in profound and meaningful ways).

• Implement smooth interpolation of the string lengths and amplitudes, using a variety of functions, with a time constant too. An example line of the new score file might look like

  time	pitch	amp	func	ptime
  3.0	440.0	1.0	3rd	0.10

  
  specifying use of a cubic spline to get to
  the right pitch and amplitude in 0.1 seconds
• Use the current average amplitude of the source (excitation) file to control modulation of the string length.
• Try to deduce the pitch of the source and change string length based on that. It might be most musically interesting to have the length be drawn from a table of allowable pitches.

Whatever you decide to do, you must write it up like a mini independent work project.
