Ambient PVC is a generative music system designed to accompany performances on a ney style PVC flute.

Run main.pd to get started. Ambient PVC uses the [plugin~] object from PD-extended and the plate2x2 LADSPA plugin from CAPS. If you don't have either of these it shouldn't affect anything beyond the quality of reverberation used in the patch.
If you want to build your own flute you can use fluteCalc.lua to figure out where to put the holes. Tweak the variables in the file to match your requirements.
