You NEED to install and configure the QuNeo library on Quarks.


A QuNeo's Sampler melodic and expressive with different scales.

  Usage :
Horizontal pad => second for heptatonic scale.
Vertical pad => third for heptatonic scale.
For change the configuration, see variable padsDegree.

pad X => frequency of the vibrato.
pad Y => amplitude of the vibrato.

circles[0] => change the scale.


If you have a problem with the 15 pad, see http://new-supercollider-mailing-lists-forums-use-these.2681727.n2.nabble.com/QuNeo-Quark-tp7598479p7603927.html
