You mean Particle Chamber ;-) Probably this discussion is better had on 
the PD list at this point, but I'll answer this one here and we can move 
over if it gets any deeper.

What the first messages is literally saying is that objects which handle 
simple numbers don't like to receive audio signals in PD. The second one 
is saying that an object's inlet is expecting some other kind of message 
than the floating point number it is receiving.

This means that there was probably an error making an object somewhere, 
because I probably wouldn't make such a silly error in programming ;-) I 
suspect a missing external or nameclash problem. Does the patch still 
make sound?

Here's a few things to do:

1) Delete the reverb section using [freeverb~], save the patch as a copy 
and try opening that one. The [freeverb~] object was easy to find for 
all platforms when I wrote Particle Chamber a year and a half ago, but 
now it's kind of droppped out of sight. The reverb section is "optional" 
anyway. This alone migh fix both errors. I'm removing the [freeverb~] 
dependency from Particle Chamber for future releases, or else I will 
include binaries of the object for all platforms.

2) Look in the PD terminal and see if you find a message anywhere that 
says "could not create object". That means you are missing an external 
library somewhere. You can post me off-list with the name of the object 
and I can probably tell you what's missing.

3) You can use "Find" in the PD menu to find the last error, and it 
should open up whatever subpatch the last object which caused and error 
is in and highlight the object in blue. Let me know which object it is 
and we can fix this.

4) Check your externals. Most of the OSX installers out there include a 
large selection of PD externals, so they should be installed (unless you 
compiled from source, etc etc). In PD, you have to use a startup file 
which was called ".pdrc" in PD <=0.37 and is called ".pdsettings" in PD 
>=0.38. The "loadlib" flag tells PD which externals to load. Here is my 
".pdsettings" file, located in my home directory (don't copy it 
directly, as I'm using differents paths and audio API!):

audioapi: 5
audioindev1: 0
audiooutdev1: 0
audiobuf: 50

midiindev1: 2

Good luck!
