 + What is QMIDICurves ?
 
 QMIDICurves is a simple Jack application that lets you change in real time midi velocity.
 The usual application is for changing the velocity curve of your MIDI keyboard.
 
 How to use QMIDICurves ?
 
 Just launch QMIDICurves. A dialog box appears that lets you choose between four curve configurations:
 
 - Flat: output velocity is always set to value 64
 - Linear: output velocity equals input velocity
 - Concave: X² curve
 - Convex: logarithm curve
 
 If the configuration above does not correspond to your need, you can create your own. For this, you need to create a curve file.
 
 Curve file format is:
  
  index_1=value_1
  index_2=value_2
  ..
  index_n=value_n
 
  where index_i is the input velocity value in range [0..127] and value_i is the corresponding output velocity in range [0..127]
 
  A linear interpolation is done between index_i and index_i+1. Indexes for which interpolation cannot be computed are set to 0.
 
  Consider the following example file:
 
  0=0
  64=20
  127=127
 
  Values will be interpolated between index 0 and index 64 and between index 64 and index 127.
 
  Consider now the following example file:
 
  0=0
  65=20
 
  Values will be interpolated between index 0 and index 65. Values between index 66 and 127 will be set to 0.
  
  Enjoy !
