    Hi everyone, i'm trying to send a polyphonic (11 voices) midi note out to a midi automated flute. Each note of the flute is the result of a unique combination of closed and open holes, so i have to refresh the status of every 11 holes for each note.

    The abstraction i'm using works relatively fine (sometimes but rarely, pd freezes when i use it) but when i use it with DSP on, and pd as a dsp insert for other instruments i use, it crackles at each note played.

    I had the same problem with a sorting abstraction. Using a better made one using lists solved the problem. So i hope it can be done better.

    Here is the abstraction i currently use: noteoutflute.pd

    I multiplied triggers to be sure everything is done in the correct order, however i suspect that so many bangs is causing audio crackles.

    I tried to connect all the note out messages to the same noteout object but it doesn't work at all (???)

    Should I try with a list, an array, and/or midi out object instead of noteout? I'm kinda lost.

    Thanks for reading this too long of a post!

    @whale-av I decided to erase every .reg file out of frustration, and pd vanilla 64 bit works again, taking 0 to 2% of cpu ! metro object sounds precise enough to my ears so i won't try to mess with -nosleep and such. If I come across the right .reg file to erase, so pd doesn't forget every preference, i will up this post with the info. Thanks again!

    Hi everyone, first post here, this forum and great community already helped me a lot, thanks !!

    I'm stuck with this problem:

    when i launch puredata, it uses 25% of cpu, which corresponds to one full cpu core (!!!)

    I tried with or without -rt, -nosleep, -sleepgrain <1>, blocksize <64>, it doesn't change anything (i use these tags to increase precision in timers, delays and metros)

    I tried reinstalling it, i tried it in 32 bits, i tried it in different priority modes with windows task manager.

    i tried with pd-extended and no problem! 0 to 2% cpu usage with dsp off, even with fat midi patches...

    ...but the metro object in it is erratic (skips some beats !), contrary to vanilla's, so i'm currently stuck with a cooking-egg hot and howling fan laptop.

    Anyone encountered this problem?
    any help would be much appreciated!!
