Hi, I am exploring the new  experimental syntax in csound6 :


a1 =
poscil(p4*randi(1,1,0),p5+(poscil(5000,100,2))*line(0,p3,1)+lfo(4,2,0),p6)


it's amazing, it works with all the opcodes? in the future there could be
radical changes on this new syntax?

I try with pluck but does not work : 

a1 = pluck(p4+lfo(.5,1),p5+lfo(4,2,0),p5,0,1)  ; work

a1 pluck p4,p5+lfo(4,2,0),p5,0,1 ; work

a1 pluck p4,p5+randomi(1,4,8),p5,0,1 ; error

what is wrong?I also noticed error using the spaces

I'm developing a simple library for Pwgl, to make orchestras, score,
algorithmic composition, etc., this new syntax would help me a lot for my
project!

Best

Giorgio

Hi, thank you, i have read the manual but I still do not understand what is
wrong

for example :

a1 = pluck(p4*jitter(.1,2,6),p5+lfo(4,2,0),p5,0,1)


works perfectly, if I replace jitter with randi or randomi or randomh give
error,  I am wrong or is it a bug? thank



Giorgio

Hello Giorgio,
i guess it has to do with this (developers correct me):

The main limitation is that only opcodes with single outputs (or no outputs)
are allowed. In addition, opcodes with multiple optional outputs will not be
parsed successfully in this form. An alternative to allow for these is to
wrap them in user-defined opcodes, or just to intermix standard Csound
syntax with this new style.

To resolve opcode ambiguities, we have introduced type annotations, in the
form of op:type(exprlist). For instance the code:

   a1 = oscili(oscili:k(p4,p5), 440)

will choose a control-rate opcode to modulate the amplitude of the audio
carrier, rather than an audio rate one. There will be cases where the type
annotation will be required, when the input arguments cannot be used to
determine the correct type of opcode to be applied.

Because , in the case of randi, for instance, the default is randi:a (audio rate), and
pluck does not take audio rate amplitude (‘a’ arg type):

 error:  error: opcode 'pluck' for expression with arg types akpcc not found, line 14 

In this case, it is mandatory that you select the randi version you want with a 
type descriptor

 a1 = pluck(p4*randi:k(.1,2,6),p5+lfo(4,2,0),p5,0,1)

and that will work. If you read that page I linked, it’s explained there.

Hi Francesco, jitter, randomi, randomh, randi are all opcodes with single
outputs, if  try with :

lfo, vibr, jitter, random

work perfectly, why don't work with randomi, randomh , randi ? an other
example :

instr 1

a1 rand  p4

a2 tone a1,(jitter(1,3,1)*1000)

out a2

endin


work! but if replace with :


a2 tone a1,(randomi(1,3,1)*1000)

error in performance

I think there is some ambiguities here:

"opcodes with single outputs (or no outputs) are allowed"

maybe, at least for me, this should be type of outputs, because i could
understand 
numbers of outputs, i.e. mono or stereo.
But i am really a basic user.

Ciao,
francesco.

Hi Girogio. Try this:

a2 tone a1,(randomi:k(1,3,1)*1000)

You need to use type annotation as randomi can be both a and k rate
but the second parameter of tone is k-rate.

Apologies, I meant to write Giorgio!

Hi Rory! thanks, now work, this new syntax is very useful for a my Lisp
project for csound and Pwgl :
