Hi,

I'm trying to make a flexible harmonizer, and for this, I want to analyse a
sound in one instrument, and make a resynthesis in other instruments
controlled by midi keys, eventually with adding other effects. 

The algorithm I use works very well inside a single instrument, even with
multiple transpositions, but because I don't know how much instances of the
resynthesis  I need, I have to find a way to send the analysis signal to
other instruments.

I tried to do it with outletf and inletf, but csound crash when I add
pvsynth in a receiving instrument.

Here is a simple example: (I use diskin here for easy testing, but it works
also with inch)

connect "source", "source_outlet", "dest", "dest_inlet"
alwayson "dest"

giFFTsize = 512
giHopsize = giFFTsize / 16
giWindow  = 1

instr source
  asigIn diskin p4, 1, 0, 1 ;soundfile given in p4

  asigIn tone asigIn, 4000 ;lowpass-filter
  gkInCps, gkInRms pitchamdf asigIn, 100, 500, 200 ;pitch tracking

  fSig pvsanal asigIn, giFFTsize, giHopsize, giFFTsize, giWindow
  
  /* ;this part works from here:
  kKey = 60
  fTransp pvscale fSig, cpsmidinn(kKey) / gkInCps, 1
  aSig pvsynth fTransp
  outs aSig, aSig
  */
  
  outletf "source_outlet", fSig
endin

instr dest
  fSig inletf "dest_inlet"
  
  kKey = 60 ;will be a parameter
  fTransp pvscale fSig, cpsmidinn(kKey) / gkInCps, 1
  aSig pvsynth fTransp ; <- crash when adding this line
  outs aSig, aSig
endin

Any ideas ?

Best,
Bernard

Do global variables do what you want?

Yes, it works ! Thank you very much !
I didn't know that we can have global f-variables.
Great!

yes it is here: https://csound.com/docs/manual/OrchKvar.html

what is not good on this manual page is that arrays are not described 
properly; but global f-sigs are there.

Initialisation is missing too, but I found it:pvsinit
(necessary when the receiving instr is declared before the other, f.e. midi
instr 1,2,3..)
