Midi sequencer android porting issue

chanof

Hi there, I would like to convert the following midi sequencer to android An error occurred; Failed resolution of: Ljavax/sound/midi/MidiSystem I think something wrong around MidiBus, The sketch never open it's self on my phone. There is someone who could help me?

Thanks a lot! Giammy

i suppose that your lib (themidibus) uses javaFXsound which is not supported by android. As for android, mediaplayer can read .mid files. For something like your code is doing you need another lib: i have used libpd for that with some results. This lib supposes that you install pd (vanilla).

chanof

Hi, thanks you for your help! may i ask how to use libpd? It's not on contribution manager, has you say it need pd but where, and how to recall it on the processing sketch? The best may be if you can do an example with code or maybe tell me a link? Thank you!

akenaton

@chanof=== sorry: i have done that with Eclipse && never tried with P5...when i get some time i ll give a look. But i am quite sure that it is possible.

chanof

Thank You!

Hi Akenaton, i have an issue with libpd, according to http://robertesler.com/libpd-with-processing/ it need jack audio that is not already for new os as mine: sierra. And i think i can't install audio jack on Android, so, how you configure it? it work on android without jack?

akenaton

@chanof===

seems that your link is too old see here: https://github.com/jackaudio/jack2/issues/144

(last comment from 2016, so it s possible that the last release woks with sierra)

chanof

Hi akenaton may i ask if you have experience about send midi with libpd thru the midi usb of the android device? I try libpd, and read some guide and i don't find this possibility thanks in advance
