diving into the audio territory of pure data... initially i wanted to build a waveform display for ofelia, the result is kind of a sampler "instrument".
the patch needs the ofelia library. the sample play mechanism is based on the sample-looper patch from continuum https://github.com/residuum/Puredata-abstractions
you can control the sample with the keyboard, if the ofelia window is in focus:
space = load sample
p = play / retrigger sample
l = loop mode / one shot mode
i = pause
s= stop

@Jona Great work! I tried it and it work very well.
I think you need to explain how to load and play samples using the keys.
Or maybe you can add a button to load sample and a toggle to play/stop the sample.
I personally think it would be nice if there's an audio export feature as well.

@cuinjune thanks. i updated the description, i have to admit the one inside the patch is not very obvious.
i also thought about buttons in addition to the keyboard control, but i think for now its fine. yes, an export function for creating samples from longer wav. files could be nice, perhaps including the current speed and pitch settings? lets see.

i added the beat mangle mechanism from this patch: http://blog.loomer.co.uk/2009/10/beat-mangling-with-pure-data.html
