	hi, is it possible for somebody to give me an example of writing a score in Lua inside a csd with bin= lua ? i'saw some exemple in python but will be very happy to find some in Lua. thanks stf

	It also is possible to use the Lua opcodes, if you have LuaJIT installed on your machine, to write your score directly as Lua code embedded in the Csound orchestra header. See examples/opcode_demos/lua_scoregen.csd for an example.

	Thanks for your help John, i understand the way we can use bin=.. sytem (i already use it with ngen from Michael Khun) but what i'm searching for is a short typical loop / print script as we found in python for generationg line of score but in lua (because i know nothing to Lua and i 'm not a programmer in mind and my always best way for learning a programming language is to do music with it ;) stf 2013/3/13 Stephane Boussuge <stfboussuge@gmail.com> Thanks Michael, but i searching for the example folder but it's not here in the new csound .dmg (mac OSX) 5.18 or even 5.19.... could you give me a point to find it ? thanks stf 2013/3/13 Michael Gogins <michael.gogins@gmail.com> It also is possible to use the Lua opcodes, if you have LuaJIT installed on your machine, to write your score directly as Lua code embedded in the Csound orchestra header.

	And, this example has such a loop as you are looking for: local c = .93849 local y = 0.5 local y1 = 0.5 local interval = 0.125 local duration = 0.5 local insno = 1 local scoretime = 0.5 for i = 1, 200 do scoretime = scoretime + interval y1 = c * y * (1 - y) * 4 y = y1 local key = math.floor(36 + y * 60) local velocity = 80 -- Format each iteration of the logistic equation as a Csound score event and schedule it. local message = string.format('i %d %9.4f %9.4f %9.4f %9.4f', insno, scoretime, duration, key, velocity) print(message) csoundApi.csoundInputMessage(csound, message) end Just remove the final line of this loop (the csoundAPI call) and you should be fine.

	I have done it both ways too, but as a programmer who used programming languages before I found Csound I rather like the templating (or %s formatting even) of those languages so all I need to do is %s %s %s And with string building it's especially powerful, like bringing together a team of people to accomplish some extraordinary feat.
