Dear all,

I'm having trouble changing my output file during a performance - is that
not possible?

In the following I was expecting two output files each with one sounding
note "rec0001.wav" and "rec0002.wav" - but I get both notes in one file,
"rec0000.wav".



-o dac



sr = 44100
ksmps = 32
nchnls = 2
0dbfs  = 1

gkrecord init 0
alwayson "master"
connect 2, "masterin", "master", "in"

instr 1
gkrecord init p4
endin

instr 2
asig oscil 0.5, p4, 1
outleta "masterin", asig
endin

instr master
ain inleta "in"
outs ain, ain
if (gkrecord != 0) then
Sfile sprintfk "rec%04d.wav", gkrecord
fout Sfile, 18, ain, ain
endif
endin



f 1 0 16384 10 1
i 2 0 0.5 400
i 1 1 0 1
i 2 1 0.5 500
i 1 2 0 2
i 2 2 0.5 600
e

Thanks Rory, that works!

Now I just have an issue with 'bypassing' the fout statement before a file
is supplied - in the following, if I replace "rec0.wav" with "" (empty
string) I get an 'invalid file name' error.

Is it possible to conditionally 'bypass' fout?




-o dac



sr = 44100
ksmps = 32
nchnls = 2
0dbfs  = 1

gSfile init "rec0.wav"
alwayson "master"
connect 2, "masterin", "master", "in"

instr 1
gSfile init p4
endin

instr 2
asig oscil 0.5, p4, 1
outleta "masterin", asig
endin

instr master
init:
Sfile = gSfile
ain inleta "in"
outs ain, ain
kcomp strcmpk Sfile, gSfile
if (kcomp != 0) then
  reinit init
endif
kcomp strcmpk Sfile, ""
if (kcomp != 0) then
  fout Sfile, 18, ain, ain
endif
endin



f 1 0 16384 10 1
i 2 0 0.5 400
i 1 1 0 "rec1.wav"
i 2 1 0.5 500
i 1 2 0 "rec2.wav"
i 2 2 0.5 600

I actually already have a conditional if-test around the fout code, but it
seems that it is being called even if the condition is false.. is it that
the if-calculation is only performed at k-rate and fout is somehow called
(with the empty string) before the first k-rate calculation..?

this was my thought, too.  you could perhaps start it directly from your 
instr 1 (if p4>0).
and you could use the monitor opcode in the recording instrument to get 
the main output.

if you like, post again, and we cann suggest improvements.

Good idea - that's a much 'cleaner' solution:) Thanks, Søren
