Max 4 Live Devices
These are just a handful of Max 4 Live devices i've made. Download them for free, use them, alter them, whatever your heart desires.
I'm planning on writing some jitter based M4L devices, although there are some already great ones for 32 bit Ableton Live that you can find at http://vizzable.zeal.co/ (I am in no way associated with them, I just like their products). Other future Devices may include some Csound For live devices, but probably not since just getting csound~ to work might make your hair turn gray and wind up throwing your laptop out the window.
As long as you have Ableton Live 9 or 8 I believe, you should be able to use these devices with Max 7, or Max 6 (full or runtime). If you have any questions or issues, feel free to get in touch here.
