Hi!
I have posted a stab at a granular synthesis abstraction at: https://www.puredata.org/Members/jb/a_grain%7E/view
It is really nothing special especially compared to the likes of Particle Chamber et al, but I thought I would make it available anyhow, just to add another example for people to try if they want. It is a one voice synth, but multiple instances are possible. I intend to add other features such as grain level resonance and grain sieving soon. It only requires PD and the expr external to run.
It is a mess as I haven't had time to tidy it up, but any comments or suggestions would be appreciated.
Enjoy!
Jamie
