I have made a multi-stage allpass filter in mxj~ by modifying the phaser.class in the mxj~ examples. I would like to port this to a C module but I am unsure how best to rewrite the code (It uses classes). Is there a simple way that I can use C++ in a max module? Does anyone have a template for doing this? I can't use flext since I need to make a UB version.

I think it would be easier to rewrite the code in plain-vanilla C 

rather than try to port flext to XCode/Mach-O/UB (although I don't 

consider the latter a massively impossible task, either). Or you 

could write your own C++ wrapper if you're determined enough (that's 

probably the hardest of the three options).

Porting Java to C is not hard. You will want a complete sample MSP 

object to use as a starting point, but the MSP SDK gives you all you

Actually, flext seems to compile and run ok under Mac/Intel. The only 

thing is that i haven't had time to update the build system, so you 

would have to make your own xcode project (for a statically linked 

build it's easy: just link in all flext .cpp files, and define

Oops, i forgot... this is only valid for the cvs version, not the 

flext cvs can be fetched from anonymous@pure-

Oops, i forgot... this is only valid for the cvs version, not the  
packaged one on my website.
flext cvs can be fetched from anonymous@pure-

thanks for your replies. In the end i found it was very simple just to port it to C.
