FOOT CONTROLLER BEHAVIOURS/GESTURES
Create pd patch that gives you 'behaviours' per switch. Ill be happy to share mine but Im just cleaning them up atm.
eg I have 4 standard behaviours that dont take too much time to master

1. Action A: A quick click (less than 500ms) Always the primary action
2. Action B: Long click ie 1 click down and pedal up after 500ms. I use this eg always as a negative ramp down for things like lowering volume but if its just held down and released in a natural way, it is the secondary action of the switch
3. Action C: 3 Click ie 1 quick down, up and then hold down. I use this for a positive ramp eg as volume up
   4 Actiion D: Double click, Always a cancel
   These are all mapped to note/ctrl outs that match the 'Selected Track Control' below

PLUGIN
Use PD VST to create a plugin version of your patch. This is loaded into Live as a control track. Live manages the connection of your floor board etc into the actual track so you dont wrestle with the io. I always use track 1 for click (forget Live metronome, this is much more flexible and can have feel/swing etc) so I dedicate track 2 to control.
Use LoopMIDI to create a virtual midi cable that will go from this track and be fed into the remote script.

REMOTE SCRIPT: 'Selected Track Control'
Download latest from http://stc.wiffbi.com/
Install to live and make sure your notes/control conform.
Enable this as a control surface in live and connect midi in from the plugin. Think about giving the guy a donation...massive amount of work and he deserves it!

I use it to control 8 tracks x 8 scenes and is controlled by 3 switches

1. Scene control up and down (A = down, B = up)
2. Track control same as scene
3. Rec/Fire/Undo Volume up and down (A = fire/rec, B = Volume Down, C = Volume Up, D (Dbl Click) = Undo

The scenes and tracks wrap so there isnt too much foot tapping

There is quite a bit more to it of course...its and maybe no one else needs this but it would have saved me a couple of weeks of time so Im happy to help anyone wanting to achieve gigging without a massive floor rig and an easy way to map and remember.

HTH someone
