That's nice, thanks. I was indeed hoping that we could have a simple C external that did not rely on flex! I thought Purr was using the original one.

I also see now this uses a modification of pdlbbuilder? Anyway, that also makes things much easier! 

Now, I did try to use and build this, I got the complaint I needed fluidsynth.h, since I'm on a mac, I did "brew install fluidsynth", hit "make" again, and it built it!!!! So excited about this that I am replying to the email before testing it :) 

Now, Esteban is also excited here and willing to compile this for Windows and Linux, what's  the step for those?

And I assume the external works fine for people who don't have fluidsynth installed like I did with "brew install fluidsynth" right?

Cheers
