Hello All,

1 -
i'm trying Csound6 builded yesterday but i'm not getting audio 
when using API in Lua (using csound in terminal is ok). I guess something is
wrong 
here, but i don't know what.
Anyway the output seems ok (except for amp 0!):

SECTION 1:
Parsing successful!
inactive allocs returned to freespace
end of score.		   overall amps:      0.0
	   overall samples out of range:        0
0 errors in performance
Elapsed time at end of performance: real: 10.198s, CPU: 0.570s
1906 256 sample blks of 64-bit floats written to dac

My system: Ubuntustudio 13.04 64 bit.

2 -
how can i setting the number of channels in csoundSetOptions?
Because using the example like above i have only mono output.

Thanks All,
ciao,
francesco.

The example is the same posted by Mr. Lazzarini some time ago:

require "luaCsnd6"

local cs = luaCsnd6.csoundCreate(None)
luaCsnd6.csoundSetOption(cs, "-+rtaudio=jack")
luaCsnd6.csoundSetOption(cs, "-k 48000")
luaCsnd6.csoundSetOption(cs, "-r 48000")
luaCsnd6.csoundSetOption(cs, "-dodac")
luaCsnd6.csoundStart(cs)
local perf = luaCsnd6.CsoundPerformanceThread(cs)
perf:Play()

luaCsnd6.csoundCompileOrc(cs, [[
instr 1
k1 linseg 0, p3*0.1, 1, p3*0.7, 1, p3*0.2, 0
a2 oscili k1*p4, p5, -1
schedule 1, 0, 2, 10000, 330
outs a2, a2
endin]])
