polyhonic sequencer

hey all,

spent alot of time searching for a polyphonic sequencer for max but couldnt find one, so i figured i'd throw this up just incase anyone else was interested.

its basically just a simple step sequencer but it allows polyphonic lines.

i've included some notes inside the main patch which should hopefully make everything clear.
i've also uploaded an example patch and the "innards" of the machine just incase

hope someone else finds this useful too
