Hello, 

In online manuals, the CSound book, etc... I see mosty constructions like
this: 

;;;;; Official TOOT09 Global Reverb ;;;;;; 

          instr 9 
idur      =         p3 
iamp      =         p4 
iskiptime =         p5 
iattack   =         p6 
irelease  =         p7 
ibalance  =         p8                       ; 1 = left, .5 = center, 0 =
right 
irvbgain  =         p9 

kamp      linen     iamp, iattack, idur, irelease 
asig      soundin   "hellorcb.aif", iskiptime 
arampsig  =         kamp * asig 
          outs      arampsig * ibalance, arampsig * (1 - ibalance) 
garvbsig  =         garvbsig + arampsig * irvbgain 
          endin 


          instr 99 
irvbtime  =         p4 
asig      reverb    garvbsig,  irvbtime      ; put global sig into reverb 
          outs      asig, asig 
garvbsig  =         0                        ; then clear it 
          endin 

Now I don't understand this. If I wanted global stereo reverb: 

  - why would I send only the mono signal to garvbsig? I would expect two
global variables for left and right. 
  - why is instr 99 a "dual mono" instrument but it is still called a stereo
instrument? 
  - why does the CSound book mentions on page 58: "Note that the dry signal
is still sent out directly, using the out opcode."? What is wrong with
leaving that part out of instr 9? 

Greetings, 
-d- 
P.S. : this is my first post, I hope I don't break any rules :)

possibly for ease of use and only hyaving a mono soundfile. You can of
course have two reverb inputs.

It is stereo, it output two channels, which are supposed to be used as
left and right, which makes it stereo. Well the input in this case is
mono, but you can rewrite that.

And put it where? Nowhere at all? Possible? Putting it into the reverb
instrument gives you less control over dry/wet mixing.
