[PD] Pd on Android

[Pierre Massat]

Thank you all for your replies.

I m not sure if the poor latency will be much of an issue for me. The reason
why i wanted to go for Android is because it seems to be more open than the
rest and i thought it'd be easier for me to develop small apps that i could
share with some relatives (not necessarily based on Pd).

Now regarding my use of Pd in Android. I don't need to do anything fancy,
all i'd like to develop for now is a small 2 or 4-track recorder, to help me
work on my new songs in a more flexible way than with my old cassette
recorder. So how should i go about it? Can i use ScenePlayer with a patch
that does just that? Or should i develop my own native app in android using
libpd (which is still very obscure to me at the moment)?

Cheers!

Pierre
