PipeSplit: 
Can be also controlled by CC27. Shifts the register breaks of a flute 
by +/- 1 semitone. Crossing a register break when playing a real flute 
requires a rapid change of both the pipe length and the overtone. This 
leads  to  a  characteristic  “knock”  when  playing  legato,  particularly 
audible when playing a trill. (More on the physics of the real instrument 
at  https://audiomodeling.com/technology/swam-w  ).  Setting  the 
PipeSplit  to  “Auto”  eliminates  this  unwanted  side  effect;  if  the  trill 
crosses this register break, the split point will be automatically shifted 
+/- 1 semitone to remain outside the trill range. 
Default register breaks (i.e. when PipeSplit = 0) are
:
Flute: D4 / Eb4, D5 / Eb5, A5 / Bb5 
Piccolo: D4 / Eb4, D5 / Eb5 A6 / Bb6 ** 
Alto Flute: Bb3 / B3, Bb4 / B4, F5 / Gb5  
Bass Flute: Eb4 / E4, Eb5 / E5, Bb5 / B5 * 
  * By default, the Bass Flute is transposed one octave above its original pitch in order 
to fit a 5-octave keyboard 
  ** By default, the Piccolo is transposed one octave below its original pitch in order to 
fit a 5-octave keyboard 
Harm.Struct: 
Spectral characteristics of the instrument (balance between odd and 
even  harmonics).  In  contrast  to  the  other  SWAM  instruments,  the 
Harm.Struct  parameter  is  placed  under  the  Key  Noise  parameter, 
replacing the Dyn.Harm parameter.
