streicherMODUL3 is an algorithmic composition.
The "building blocks" of the composition are groups of tones, which are looped. Every instruments plays one individual groups.
Now these groups are transformed: they get condensed, widened, different playing techniques, etc.
Additionally the 4 strings are out of tune against each other in eight tones - so a micro-tonal network arises.
The algorithms are implemented in PD.
All instruments are controlled via curves as shown in picture 2.
