py4pd

Python in the PureData environment.

py4pd allows write PureData Objects using Python instead of C/C++. The main goal is to allow easy IA, Scores, Graphics, and bring to Pd possibilities with array, list and others types. With Python, you can:

• Parse svg/draws as scores;
• OpenMusic functions in libraries like om_py, music21, neoscore, and others;
• Sound analisys with magenta, librosa, and pyAudioAnalaysis;

• Go to Docs (outdated for now), check Sources/py4pd folder for examples.

New Pd Object using Python

import puredata as pd
import os

class pymetro(pd.NewObject):
    name: str = "pymetro"

    def __init__(self, args):
        self.inlets = 2
        self.outlets = 1
        self.toggle = False
        if len(args) > 0:
            self.time = float(args[0])
        else:
            self.time = 1000
        self.metro = pd.new_clock(self, self.tick)
        self.args = args

    def in_2_float(self, f: float):
        self.time = f

    def in_1_float(self, f: float):
        if f:
            self.toggle = True
            self.tick()
        else:
            self.metro.unset()
            self.toggle = False

    def in_1_reload(self, args: list):
        self.reload()

    def tick(self):
        if self.toggle:
            self.metro.delay(self.time)
        self.out(0, pd.SYMBOL, "test238")

Building from Source

• To build from the source code:

cmake . -B build -DPYVERSION=3.12
cmake --build build

On windows you need Mingw64.
