i am making a very big project with lots of objects and ect
am i limited to how may objects and gui things that i use?

yes, of course.

each object uses a small amount of your computer's CPU resources. If you use a lot of objects, you start to fill up the capacity of your computer, or device.

think of it like this - each pd object is like one golf ball. you can carry 1 or 2, or 100 golf balls very easily.

but if you have a huge bag full of 10,000 golf balls, it gets very heavy.

(but you have a better chance of getting a hole in one

Hi, ShawnPD:
Try to use as few gui objects as possible. Hide every unnecesary thing into a subpatch. A friend of mine who is a professional programmer told me that tcl/tk interface (the one used for Pd gui) refreshes its objects in a serialised way, one by one. If you have a lot of them, each time you switch desktops back to the one containing Pd, you will experience a gap in the audio processing. That's the main bottleneck I've run into.
I'm currently working hard on getting over it. I hope in not more than a month from today I'll be posting something regarding this issue.

All the best.

as far as built in limits, i can't say for sure, but i think pd will let you add as many objects as you want, until your computer crashes.

thanks for your help now i have to start downsizing things, its staring to crash on me and i have to add 20 or 40 x 4 more things : )
man i dont like sub patches to much.

start by deleting any GUI objects that aren't absolutely necessary. especially things like toggles or number boxes that are constantly updated while the patch runs - get rid of them if you can.
