Introduction

A screenshot of pd-bee patch

Startup​

Initial values of the patch are:

  • masterBass: 1 (value from 0 - 2)
  • masterMid: 1 (value from 0 - 2)
  • masterLow: 1 (value from 0 - 2)
  • useEq: 1 (value 0 or 1)
  • volume: 1 (value 0 - 100)
  • fileLoop: 1 (value 0 or 1)

Dependencies​

  • foonLib: a library written by aifoon to start playing files
  • ggee: ggee is a library by Guenter Geiger with five sections: control, experimental, filters, gui, and signal.
  • readanysf~: a patch to read a wav file
  • osc: a collection of Pd objectclasses for OSC-messages. These objects only convert between Pd-messages and OSC-messages (binary format), so you will need a separate set of objects that implement the transport (OSI-Layer 4), for instance [udpsend]/[udpreceive] for sending OSC over UDP. Written by Martin Peach.
  • iemnet: this is a fork of martin peach's "net" library, that allows low-level interaction with networks on OSI-layer 5 (transport layer).

OSC Actions​

You can send an OSC message over UDP to the bee, to port 9001. This is the protocol

  • /masterBass [0-2]: sets the lower frequencies
  • /masterHigh [0-2]: sets the higher frequencies
  • /masterMid [0-2]: sets the mid frequencies
  • /volume [0-100]: sets the volume
  • /fileLoop [0 or 1]: sets the file loop
  • /useEq [0 or 1]: sets equalizing
  • /start [name of the file].wav: start a file with the given path (files ore stored on in /home/pi/pd-bee/files/[filename].wav)
  • /stop: stop the file playing

Stream and trigger​

  • Any incoming stream is send to the left and the right channel of the speaker.
  • For triggering, the left and right channel are splitted to the left and right channel of the file itself
