Max/MSP Patch to Arduino

Hi All
I've been a programmer for a while but am brand new to Arduino and want to see how much it can expand my live music.

I've programmed (almost finished) a complex MIDI sequencer, sample playback and effects patch. It pulls MIDI files and samples from an SD card. This was designed to be used live but I want to avoid using a computer if possible. I've got two plans to bring the patch to life hardware wise. Ideally I'd like to build a standalone unit which holds the SD card and does all the processing. Is it possible to convert Max patches into code for the Arduino to do this?

Failing that my alternative plan is to create a dedicated tablet to run the patch and do the audio processing and make an Arduino controller for the LEDs and Buttons. So any suggestions as to moving the patch onto something hardware based would be amazing.
