Thanks for your reply vince 
the LEDs are set up like so:
35 34 33 32 31 30
24 25 26 27 28 29
23 22 21 20 19 18
12 13 14 15 16 17
11 10 9 8 7 6
0 1 2 3 4 5
With the code that i uploaded turning the lowest and leftmost LED on and off .
I have removed one column for the game as the sequencer element will have control parameters placed in these 6 empty slots, and the aim is to create an interactive music tool, so this is one of the sacrifices I had to make.
I would ideally like to have 4 buttons to move the LED up, left, right, and down, and one button to confirm the players choice, and switch to player 2. in this way it is fairly different from original connect 4 again as the counters do not all drop to the bottom, and can be placed anywhere regardless of the fact that there are no counters underneath them in a column, I would prefer this as it means that when the sequencer element of it is in use, it can be utilised a lot more effectively.
Thanks again for your reply, Andrew
