Hi Marcus Marcus Flanagan hat gesagt: // Marcus Flanagan wrote:
I'm trying to build a PD system that recognises the key that I'm playing in with my keyboard. I've looked at the arrays and textfile objects...but they seem hard to follow.
Can someone take the time to explain how I would get PD to read in a set of notes that are in a key(the 8 notes in the major scale for example)...and
then I can check if the notes I'm playing correspond to the notes in the file read in...and hopefully then I can use some of the backing progressions that I have.
This might be a harmonics course problem ;)
I didn't build something like that yet, but I highly recommend Peter Elsea's Tutorials at http://www.sfu.ca/sca/Manuals/247/Max/Max.html
Beware: They are on Max not on PD, but they still include valid information for PD as well: the concepts are the same. But there are some things to consider, for example I don't know of a PD object "coll". qlist and textfile aren't really replacements. A common idiom in PD is to use linked arrays instead, where one array holds the number-names or indices of other arrays, that in turn hold a chord or a scale.
Esp. "Max & Pitch" http://www.sfu.ca/sca/Manuals/247/Max/ElseaMaxTuts/Max&Pitch.html and "Max & Chords" http://www.sfu.ca/sca/Manuals/247/Max/ElseaMaxTuts/Max&Chords.html deal with the things you want to achive.
But as said they are in Max and don't give ready-to-use solutions for our PD problems, but great stuff to think about.
bye,
