-- Example 2 - Compilation with Csound without CSD

-- In this example, we move from using an external CSD file to

-- embedding our Csound ORC and SCO code within our Python project.

-- Besides allowing encapsulating the code within the same file,

-- using the CompileOrc() and CompileSco() API calls is useful when

-- the SCO or ORC are generated, or perhaps coming from another

-- source, such as from a database or network.

require "luaCsnd6"

-- Defining our Csound ORC code within a multiline String

orc = [[

sr=44100

ksmps=32

nchnls=2

0dbfs=1

instr 1

aout vco2 0.5, 440

outs aout, aout

endin

]]

-- Defining our Csound SCO code

sco = "i1 0 1"

local c = luaCsnd6.Csound()

c:SetOption("-odac") -- Using SetOption() to configure Csound

-- Note: use only one commandline flag at a time

c:CompileOrc(orc) -- Compile the Csound Orchestra string

c:ReadScore(sco) -- Compile the Csound SCO String

c:Start() -- When compiling from strings, this call is necessary before doing any performing

c:Perform() -- Run Csound to completion

c:Stop()
