Pure Data on Rockbox
This project is part of the
Google Summer of Code 2009 project.
This is a Google Summer of Code 2009 project with the goal to make Rockbox a musical instrument. To do so, the sound processing framework Pure Data will be integrated into Rockbox in the likeness of
http://www.ipodlinux.org/wiki/PdPod .
Those who do not know what Pure Data is are advised to look at the book "Designing Sound" (
http://aspress.co.uk/ds/), both at the abridged text and at the sample chapters. Another good Pure Data tutorial can be found at
http://www.pd-tutorial.com/ .
To test the abilities of PDBox get the file
PureData.zip from
http://www.ipodlinux.org/wiki/PdPod . If
http://www.ipodlinux.org/ does not work, you might want to get this file from this page (seel below).
There is a repository with updated designs at
http://pd-anywhere.svn.sourceforge.net/viewvc/pd-anywhere/branches/reware-exhibition/ipod/PureData/ . Beware of designs
Daft_Widget.pd and
dj_scratch.pd ; they contain errors which make pdbox hang! Alternatively you might use the archive
PureData2.zip, attached below.
Project Plan
Part 1 (50%): Port PDa (Pure Data anywhere, the Pure Data fixed point fork) to Rockbox
- Port network communication: done (actually, it was replaced by a small custom message passing interface)
- Port memory allocator: done (using dbestfit library)
- Porting file-for-file, looking at missing symbols in the plug-in: done
- Port audio: done (output only)
- Port file operations: done
- Port scheduler: done
Part 2 (50%): Port PDPod GUI to Rockbox
- Sending statements to Pure Data core (pauses and un-pauses were used as an example): done
- Custom GUI: done
- Standard GUI: done
Known problems
-
GUI does not take backdrops (bitmap backgrounds) into account, leading to an unreadable text/background combination -- PeterDHoye - 04 Aug 2009 - fixed
- PD designs which are based on audio files instead of (for lack of a better term) oscillators may have difficulties while loading - fixed
- Sound input capability is lacking
