MIDI Control of an EKS Patch in PD

As detailed in the Faust intro [15], we create an 8-voiced MIDI synthesizer for pd as follows:

  faust -xml -a puredata.cpp -o eks_pd.cpp eks.dsp
  g++ -DPD -Wall -g -shared -Dmydsp=eks -o eks~.pd_linux eks_pd.cpp
  faust2pd -s eks.dsp.xml

The last line produces eks_pd.pd which can be loaded into pd. In addition to the basic three MIDI-control parameters (gate, freq, and gain), we have the following additional parameters that are brought out as sliders in pd:

• Brightness
• Decay time ($t_{60}$)
• Dynamic level
• Pick position
• Pick angle (or direction)

Finally, there are some simply computed parameters associated purely with panning the output sound into the stereo field:

• Panning angle
• Spatial width

See Fig.9 and Fig.10 for details.
