NodeBeat – Created with libpd + openFrameworks
Since I didn't announce NodeBeat (http://NodeBeat.com
) when it first came out, I think now is the appropriate time since we just released a major version update for NodeBeat HD (iPhone version to follow). The new NodeBeat HD has a lot of new features including a drum generator node and drag/drop interface for music creation.
NodeBeat is an experimental node-based audio sequencer and generative music application. It's a cross between a toy and a music creator.
It's programmed in c++/obj-c using openFrameworks and uses libpd for audio via Dan Wilcox's (http://noisepages.com/members/danomatika/
) ofxPD addon (https://github.com/danomatika/ofxPd
In terms of libPD, the audio is fairly simple. It can switch between sine, triangle, sawtooth, and square oscillators, with adjustable ADR. We also use a delay line so people can control the echo. We're able to record to wav file using PD's [writesf~] object, but we compress the audio for e-mailing using native obj-c code (I can share that somewhere if interested). It would be great to find a non-GPL licensed object for PD that does audio compression; does anyone know of one?
If you have any questions, feel free to ask. Take a look at the website to get a sense of the application. There's even a free desktop version with minimal features. The video will be updated soon to showoff the new overhaul.
Thanks everyone for contributing to libPD, it's really helped making audio applications relatively painless. :)
