This is a collection of various tools, tricks, techniques for using the magic trackpad in controlling various objects in the Max/MSP environment, including sliders, multisliders, matrices, waveforms, even potentially using the trackpad as the monome arc!
This toolbox uses the external [fingerpinger] by Michael and Max Egger
(which is included) and a basic requirement is a post-2008 intel macbook with a multitouch trackpad, or a Magic Trackpad and compatible software (e.g. Mac OSX Snow Leopard or later).
Feel free to share, and get in touch if you end up using this in some exciting project, it's great to hear how others are finding ways to use the trackpad with Max/MSP!
