[PD] Midi notes.....analysis?

[Olaf Matthes]

Hi Rory,

I don't know the 'perfect' solution for your problem but had a similar
one some month ago. I tried to make some sort of score following to
enable pd to find / detect certain parts in a musical score (analysed by
a pitch-to-midi converter). If it's that what you want to do, have a
look at the patch attached.
Incoming 'notes' get stored into an array and the patch sort of compares
the last three values from a certain position on with values that are
given. You would then need to detect somehow the beginning of a chord in
this array. My musical score was just monophonic, with chords even the
order of notes might change from time to time. A way around this would
be to sort values before analysis.
I just have to distinguish between 6 different 'clue points', otherwise
the patch would have been very overcrowded. One major problem in using
this patch is the accuracy of the pitch to midi converter and/or the
performing musician. Any failure in detection confuses this stupid
patch....

Maybe there is someone who knows how to make a more 'intelligent' score
follower or tune analyser.


Olaf


PS: With your 'device out of range'-problem try starting pd with
'-midiindev 1' flag. This uses the first midi in device installed on
your system.
