I along with my fellow maintainers Alexander Torres Porres and Matt Barber have been working on updating Cyclone, the Max/MSP compat library for a year, and have just reached the point of an alpha release. Zipped builds can be found here: https://github.com/porres/pd-cyclone/releases/tag/cyclone0.3-alpha.1 and bug reports can be filed on the Issues tab of that repo. I've also uploaded it to be downloadable via Pd's built-in library manager Deken so you can search for "cyclone" and download the v0.3alpha1 build appropriate for your platform. There's a few objects that are more in-construction than others such as the GUI-related externals and have also not been ported to Purr Data quite yet.

That's great! Is there any 64 bit Windows build? I'm using Purr Data.
thanks!

@alfonso.santimone Hello, i'm not sure if that are actually any Pd libraries that are specifically 64-bit builds for Windows? if you take a look at the Pd library manager Deken and search for any of the major libraries they all list Windows-i386-32 as the build platform, so just give that build a shot on your machine and let me know if that isn't working for you. We are working on making it available with Purr Data, but it should be usable with it as of now, besides GUI and canvas-oriented objects such as [comment], [mousestate], [scope~], etc as well as anything that involves a pop-up text editor window such as [coll], [capture], etc. All of those objects basically have hard-coded Tcl code while Purr Data runs on nw.js/HTML5 (yes, even the pop-up text editor windows rely on a bunch of Tcl code, we're thinking of maybe trying to harness Pd's [text] windows somehow).
