Fairly self explanatory up to 'p timedlatch' which cuts off the signal for a short period when it's been hit to prevent double bangs coming through... Then as the 'incdec' object increases it opens a different path through the gate and the second bang from 't b b' (trigger bang bang) sends a bang through the corresponding number of the gate. Difficult to explain but not that complicated!The next screen shot shows how the FCB is routed through MAX to Ableton Live.

The FCB is programmed to send '127' out on notes 22, 23, 24 etc, these messages go either straight through to another control message into Live or they trigger a different control value... This method is still a bit messy at the moment...
