+-- ReturnOne by Paul Hedderly
+-- Sometimes you just want just an on - and from any imput but 0
+-- 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 returnjustone(v) -- Use a default function - then you can use any input channel name
+  if v>0 then output("out"..input_channel(),1) end;
