Roqba is a realtime music machine (composer, synthesizer and player)

see the documentation

You'll need Pure Data for the sound-production. Some objects rely on external libraries of Pure Data. Please see the documentation for details.

install puredata with the following extension libraries (example for a debian based linux)

    apt-get install pd-unauthorized pd-motex pd-zexy pd-cyclone pd-ext13 pd-list-abs pd-pan pd-creb

puredata creates the sounds, run it with

    pd pd/roqba.pd

or without a GUI:

    pd -noadc -nodac -nogui -stderr pd/roqba.pd

open a python shell (I recommend IPython) in this folder.

to start the app

    from roqba import main  
    main.main()  

to pause

    main.director.pause()  

to resume

    main.director.unpause()  

to stop

    main.director.stop()  

adjust speed by

    main.director.speed = <speed>  # length of the shortest note-length in seconds.

start the GUI

    python roqba/ui/main.py

follow the log-messages with

    tail -f log.txt

follow a graphical (scrolling) representation on the notes played by

    tail -f scrolling.txt
