I like to think i am pretty savvy when it comes to PD, but alas, I still have much to learn it would seem, as I cannot for the life of me solve an issue with a patch of mine that has been driving me mad for quitge some time now. When I open the patch, all midi runs fine. Everything is low latency and very usable... but the more I play around in the patch and play keys and alter settings, things get slower and slower... until finally after a while there is too much latency in the midi system to even use my patch properly. The problem is solved when I shut down PD and restart the patch, but then rears it's ugly head once againm after some time. The patch is prety complex andf has a lot fo stuff going on, but it is a midi only program. The audio engine is off, so that is not likely the cause. Im thinking it has something to do with the console stacking up, or various objects which store data stacking up and bogging down. I would like to build in some way to clear things up soo the latency never piles on too much, but I cannot figure out which object is causing it or why! Does anyone know of any onjects that are known to cause this problem so as to point me in the right direction? I can post the patch if anyone cares to see it, but I warn you that it is pretty huge and would have layers and layers of patching to dig through. Maybe there is some way to globally clear all the midi data buffers or something? any help would be immensly appreciated, as the patch otherwise works well and It's something I use in almost every session!
