Hi,
I am quite new to Pure Data......What I want to do is to convert the continuous pitch output of Helmholtz~ to discrete midi note and velocity (as the output of notein). I am finding this task quite difficult, I feel like I am missing something.
Using ftom and int I get the midi note and using env~ with one mathematical expression I get the velocity scaled 1-127 but everything is a continuous stream. I want to isolate different notes. Does anybody has suggestions?

Thanks!

@Robertoo I have not tested, but inside [helmholz~-test] is a sub-patch [pd synthesis]
Here I have tried to change it for midi notes instead of an audio oscillator.
synthesis-audio_midi.pd
The left part is the original and the right part is for Midi output.
It will only send a midi note and velocity when the note changes...... using the [change] object.

But it will get more complex if you have for example a pulsing note.
Let us know what you get and what you need.
Anything is possible.
If you need to send a note off for the previous note when a new one is sent then you will need to store the previous note in an [f] object and send it again with 0 velocity as the new note is sent.

@whale-av Thanks! actually the patch I am working on is also based on pd synthesis in helmholtz. I tried tricks all day but the results are not really satisfying. My aim is to have something this fluid https://guitarextended.wordpress.com/2012/01/06/simple-monophonic-fm-synthesizer-with-pure-data/ I am tracking an electric guitar by the way.
