Max + M4L for crow (monome/whimsical raps)
After downloading the entire crow-max-and-m4l repo, extract the zip file and you should get two unique folders: crow_max and crow_m4l.
Open Max > Options > File Preferences > highlight User Library > the rightmost icon in the bottom bar should illuminate. Clicking this icon will open the User Library folder, where you can drop the crow_max folder.
If you are performing an update of an existing crow_max installation, you can simply allow the system to replace the existing files. If you have previous crow files in your User Library (or anywhere along your Max search path), please delete them and start fresh with crow_max.
Restart Max and you should be able to instantiate the crow abstraction as a regular object!
