Override sustain pedal on a per-pitch basis with velocity = 1 note events

edited October 2024 in Scripting Workshop

I have this very simple script working fine below but it's only able to send note-offs for all note events. I want to be able to only send note-offs to note events of the same pitch as the note event with velocity = 1, the instant that note is played. 

on init

declare polyphonic $v
declare polyphonic $notenumber

end on

on note

$v := get_event_par($EVENT_ID,$EVENT_PAR_VELOCITY)
$notenumber := get_event_par($EVENT_ID,$EVENT_NOTE)

if($v = 1)
   note_off($ALL_EVENTS)   

end if

end on

The $notenumber part of the script isn't doing anything but I want it to. Somehow I need to filter $ALL_EVENTS to only include note events of the same pitch as the velocity = 1 note.

Seems like it should be really simple and I'm just missing something basic. Thanks in advance!

    if the velocity = 1 why do you need to kill these events?

    one tool you are missing is the function get_event_ids ()

    with it you can scan through the active events, check their EVENT_PAR_NOTE and EVENT_PAR_VELOCITY, if they match to your specifications, you can kill them.

    Is this for MalletKAT?

    Thanks for your reply. I would use a velocity of 0, but in Logic Pro, the lowest you can drag the velocity down to is 1. So I'm giving up the ability to use velocity 1 notes and instead using them to mute sounding notes. I'll experiment with the get_event_ids () function. Thanks again.

    I should also clarify, i don't want to kill notes with a velocity of 1. I want to use notes with a velocity of 1 to trigger note-offs for all singing notes with that same pitch. Imagine a complicated vibraphone passage with the sustain pedal active. And just one or two notes sound bad with the next chord. All I want to do is sequence mutes for those notes only and leave the sustain pedal active. Hope that makes sense.

    Sort of. I'm sequencing MIDI for vibraphone in Logic, and then importing it into Sibelius. I just want to use an X notehead on Sibelius to act as mallet mutes that will override the status of the sustain pedal.

    Do you know of a script that already does something similar?

    Something like this? (EDIT, sorry this is a mute, my mistake, change the fade_out to a note_off...)


    on init
    declare $count
    declare %array[512]
end on

on note
if ($EVENT_VELOCITY < 2 )
    get_event_ids(%array)
    $count := 0
    while($count < 512 and %array[$count] # 0)
        if( get_event_par(%array[$count], $EVENT_PAR_NOTE) = $EVENT_NOTE )
            fade_out(%array[$count], 300000, 1)
        end if
        inc($count)
    end while
end if
end on

    Even the fade-out works great!!!!!

    Please message me directly so I can pay you.

    While you're here, I did try replacing 

    fade_out(%array[$count], 300000, 1)

    with

    note_off(%array[$count])

    and it won't work. But in case you're busy the fadeout works fine for now, I'll just shorten it a bit. :)

    Been trying to figure this out for 3-4 days straight so will happily send you some thank you cash if you message me.

    Haha... you don't have to pay me, it's just something I did for MalletKat a while back.

    Not sure why note_off isn't working for you, maybe some other part of the script is affecting the release?

    Hmm, it could be several things. I'll experiment and come back if I figure it out. This gets me 99% there though, so thanks so much for your knowledge!

    Thanks for a very instructive thread.

    The principal problem is overriding the sustain pedal which I don't think can be done (note_off obviously won't release the note if the pedal is down). Fade_out is a brilliant workaround.

    That makes sense.

    So far, the fade_out is working fine. There's literally not a single bug or issue with this script and it's clean and tiny.

    If someone really needs the note_off() function though, one could change the sustain pedal with the 'on controller' callback before the 'on note' callback. Make it so note_off($ALL_EVENTS) will replace C64,0, and ignore note-offs for all note events before the if($EVENT_VELOCITY < 2). I'm not good enough yet to figure out the proper order of things but I imagine it could be done.

    Ah - remember cc64=0 doesn't release all notes, only those which have had a note-off.

    If you need the note_off to work while the sustain pedal is down, I'd say you're going to need to write your own sustain pedal routine, and SET_CONDITION(NO_SYS_SCRIPT_PEDAL)

    That makes sense. Still making sense of this stuff. Thank you!

    Will give that a try! Thanks very much!
