untrapped stderr output: "connecting to port 30322"
untrapped stderr output: "python-connected: 0"

Pd died!

Methods defined here:
- Alive(self)
- Check whether the Pd subprocess is still alive.
- CheckStart(self, msg)
- Connect(self, addr)
- Dead(self)
- Error(self, error)
- Override this to catch anything sent by Pd to stderr (e.g. [print] objects).
- Exit(self)
- Kill the Pd process right now.
- PdDied(self)
- Override this to catch the Pd subprocess exiting.
- PdMessage(self, data)
- Override this method to receive messages from Pd.
- PdStarted(self)
- Override this to catch the definitive start of Pd.
- Send(self, msg)
- Send an array of data to Pd.
It will arrive at the [python-interface] object as a space delimited list.
p.Send(["my", "test", "yay"])
- Update(self)
- __init__(self, port=30321, nogui=True, open='python-interface-help.pd', cmd=None, path=['patches'], extra=None, stderr=True)
- port - what port to connect to [netreceive] on.
nogui - boolean: whether to start Pd with or without a gui. Defaults to nogui=True
open - string: full path to a .pd file to open on startup.
cmd - message to send to Pd on startup.
path - an array of paths to add to Pd startup path.
extra - a string containing extra command line arguments to pass to Pd.
