[PD] Pitchshift frequency bins to specific frequencies

[Ronni Montoya]

Hi, i been trying csound6~ but it doesnt work on my computer i get this message:

/Users/ronni/Downloads/Spectralwarp/dependencies/csound6~.pd_darwin:
dlopen(/Users/ronni/Downloads/Spectralwarp/dependencies/csound6~.pd_darwin,
10): Library not loaded:
CsoundLib64.framework/Versions/6.0/CsoundLib64
  Referenced from:
/Users/ronni/Downloads/Spectralwarp/dependencies/csound6~.pd_darwin
  Reason: image not found


Is there any special way of installing csound6~?

Im on macosx 10.8.5


cheers


R.
