instrument modeling

---

GinSing can be configured to work like a musical instrument when placed in poly mode. Up to six voices can be played simultaneously. When entering voice mode, the DCOs. mixers, and envelope generators are configured to create identical voices mapped directly to the outout. A default envelope is applied to all voices as well to provide a more musical character. The software interface allows you to address all voices simultaneously or individually if you wish to customize each voice. Modulation is limited in this configiration, but you can model simple instrument characteristics and can use the built-in note table to generate precise musical tones, chords, and harmonies.

GinSing note selection frequencies are defined to provide a tempered Concert A 440 musical scale. You can also specify your own frequencies to each voice if needed, and bend between frequencies (or notes) for portamento and other more synth-like effects. Using only the setNote() and trigger() commands you can create a simple song:

#define NumNotes 10
GSNote bass[NumNotes] = {C_3,E_3,D_3,F_3,E_3,G_3,E_3,F_3,D_3,E_3};
GSNote lead[NumNotes] = {C_6,D_6,E_6,F_6,G_6,G_6,F_6,E_6,D_6,C_6};
GSNote treb[NumNotes] = {G_5,E_5,F_5,D_5,E_5,C_5,E_5,D_5,F_5,E_5};

for ( int loopCnt = 0; loopCnt < 8; loopCnt++ )
{
  for ( int noteIdx = 0; noteIdx < NumNotes; noteIdx++ ) 
  { 
     setNote ( 0 , bass [ noteIdx ] ); trigger ( 0 );
     setNote ( 1 , treb [ noteIdx ] ); trigger ( 1 );
     setNote ( 2 , lead [ noteIdx ] ); trigger ( 2 );
     delay ( 250 );
  }
}
