+-- ReturnOne by Paul Hedderly
+-- Sometimes you just want an on/off from linear pads
+-- For example I want to activate scenes in OBS from a Korg NanoPad2
+-- But I dont want to have to thump the pads to get a 1.0 output
+--
+-- You could use this as:
+--      [midi nanoP]
+--      read = nanoPAD2
+--      write = nanoPAD2
+--      [lua trackpad]
+--      script = trackpad.lua
+--      default-handler = returnone
+-- ..   
+-- 	nanoP.ch0.note{36..51} > returnone.one{1..16} -- To feed all the 16 pads to 
+--	returnone.outone1 > obs./obs/scene/1/preview
+--	returnone.outone2 > obs./obs/scene/2/preview
+-- etc
+-- The output channel will be the same as the channel you feed prepended "out"
+
+
+function returnone(v) -- Use a default function - then you can use any input channel name
+  if v>0 then output("out"..input_channel(),1) end;
+  if v==0 then output("out"..input_channel(),0) end;

+-- Trackpad input by Paul Hedderly
+-- Expects three sources X, Y and touch
+-- On the Korg Nanopad2 these would be nanoP.ch0.cc1, nanoP.ch0.cc2, nanoP.ch0.cc16
+-- so you could map and feed this script with something like:
+--	[midi nanoP]
+--	read = nanoPAD2
+--	write = nanoPAD2
+--	[lua trackpad]
+--	script = trackpad.lua
+-- ..	
+--	nanoP.ch0.cc1 > trackpad.x
+-- 	nanoP.ch0.cc2 > trackpad.y
+-- 	nanoP.ch0.cc16 > trackpad.touch
+--
+-- Each touch will generate four outputs
+-- - on[1-9] - the first point of touch (might not be very useful!)
+-- - off[1-9] - the final point of touch
+-- - swipe[1-9][1-9] - the first and last as a *simple* gesture or swipe
+-- - gesture[1-9]..[1-9] - every segment you touch in order so you can do complicated gestures
+--
+-- Each output of 1 is followed by an output of 0
+-- You would map these as
+-- 	trackpad.on3 > ...
+-- 	trackpad.off9 > ....
+-- 	trackpad.swipe17 > .... -- would catch a line from top left to bottom left but could go anywhere in between
+-- 	trackpad.gesture78965 > .... would catch a backwards capital L starting at the bottom left
