no , you didn't understand.
Whatever speed i'm playing between each note, whatever unconsistency i'll have while playing, all the arduino has to understand when recording it is :
note 1 ... this ( E )
note 2 ... this ( A )
note 3 ... this ...
i'll ask him to play E, then A then etc , at his own contant speed that i'll adjust ( 500 ms between E, A , etc or 400 between all the notes, or 300 etc ... ) that's all.
pc sequencers and other stuffs are crap, and nothing like what i want. i tried that before ... and the sewuenders from cubase 5. crrraaaaaaap !! that's a pity.
lol, fuck reason, fuck abbleton ; ) ha ha ! they didn't understand what i'm looking for, much more simple.
much much more simple ^^
