+-- This example MIDIMonstaer Lua script spreads one input channel onto multiple output
+-- channels using a polynomial function evaluated at multiple points. This effect can
+-- be visualized e.g. with martrix (https://github.com/cbdevnet/martrix).
+
+-- This is just a demonstration of global variables
+foo = 0
+
+-- The polynomial to evaluate
+function polynomial(offset, x)
+	return math.exp(-20 * (x - offset) ^ 2)
+end
+
+-- Handler function for the input channel
+function input(value)
+	foo = foo + 1
+	print("input at ", value, foo)
+
+	for chan=0,10 do
+		output("out" .. chan, polynomial(value, (1 / 10) * chan))
