Help/Code review with processing midi.
I'm pretty stuck and working in circles on this little project. It's my first week with Max in a few years also so I'm hoping to get some help before I lose hope.
My project is for essentially playing a melody via drum triggers. I plan to have a MIDI drum track that uses the M4L MIDI Sender effect to send notes as triggers to another "melodic" track.
On the melodic track, my custom midi effect parses and stores the MIDI notes being played and then triggers them when the Sender's trigger notes are played. I have it somewhat working where it records the pitch and duration of notes being played and then plays those when triggered BUT I have not figured out how to handle incoming triggers when the latest melodic note is still playing. At that point the duration is unknown... so I want to trigger the note-on and then trigger the note-off when the duration is resolved minus the amount that the note has already been playing. (I think).
Anyway, it's a lot of storing information and then sending that information on to be processed at the right times and I cannot seem to grok what objects to use for this kind of processing.
Maybe someone with more experience has some pointers or insight? Any help would be appreciated.
As first check repeat modes of makenote.
that can be used to control retriggering or extending notes of same pitch
which come in before previous ones gets turned off.
Your note length measuring is wrong.
Note length is only known when it ends.
But you store note length of previous note into zl.reg.
you can see it here:
first note played got stored as 54 93 with length zero !
timer measured 1207. 857789 but zl.reg has zero length
I think the whole construct is not going to work...
maybe you can read a bit in this somewhat long thread dealing with similar thing.
P.S. you can easilly fix note length detection.
but actually it is a matter of your concept - what to do when new note On
replaces previous one ?
ignore it till it ends and you know it's length ?
and either ignore trigger input, or maybe play previous note ?
Or trigger new pitch and velocity using previous note's length ?
???
you can use this or borax to get true length of notes
Thanks! That thread is such a good reference for me to learn from. I feel like I know what I want to do with everything but I haven't quite managed to figure out how to apply it so seeing these examples is great. Thanks again.
Plus part of me thinks I should just be using CC messages or Live automation to set note length since the entire melodic information is predetermined to begin with.
I would say most important thing is to
define relation beteween trigger impulses from drum pad and notes
which get targeted.
In fact triggers can play notes no matter
If live is playing or not, and which tempo it has, just like any synth.
