Hello All,
i'm working with pvs opcodes and i have a instrument that using pvsfreeze
freeze the input sound for a long time.
Input sounds are brief guitar note that are detected triggering a new 
instrument
with a long duration that use pvsanal and pvs freeze.
Now i thought that is not necessary that pvsanal is working for so long 
time so i
would like to separate the analize phase from the freeze.
So a input note trigger a brief analize instrument and then this trigger
a long duration freeze instrument.
I have tried with array in this way:

; global array of fsig array
gkFArr[] init 100


; create array for bin data
kArr[] init ifftsize+2

; export data to array
kflag pvs2array kArr, fsig

; put fsig array in global array. ifn is the number of the input note 
from 1.
kk init ifn
gkFArr[kk] = kArr

this give me:

Unable to find opcode entry for '=' with matching argument types:
Found: k = k[]

what i'm doing wrong?

Are there other way to obtain what i aould like?

Thanks,
ciao,
francesco.

Ypu are atyempting to assign a k-rate array to a k-rate variable which is 
not avaiable even if you coud explain what you wany it to do/

Perhaps you just want gkFArr[] = kArr ?

Thanks,

simply i would need to pass fsig from a instrument

to another and using many instances of these instrument

i thought i need a global array with index instance number

and containing fsig array. Like:

gkarray [instance_number] [fsig]

But i'm open to other solutions ...


Thanks,

ciao,

francesco.

Global f variable?

Thanks,

i will try to explain better what i'm trying to do.

instr 1

listen for a input note. when there is a note will start instr 2.note_number

instr 2.note_number

use pvsanal to create fsig then trigger instr 3.note_number

instr 3.note_number

use fsig for freezing that single sound


I separate analysis from freezing because analysis duration is less then 
2 seconds while freeze last for many seconds (maybe minutes).

Every note_number instance has his own fsig (one for input note).

So i would need many global f variable and i do not know how many in 
advance.

So i thought about array but i do not understand how to use it,

and if it's possible for my needs.

Thanks,

ciao,

francesco.

Lookat the opcodes
  pvsftr — Reads amplitude and/or frequency data from function tables.
  pvsftw — Writes amplitude and/or frequency data to function tables.

and possbly pvs2tab

No tried it but these seem to do what you want, going via functin tables. 
pvs2tab writes a k array which coud be a two dimensional array.  Not found 
the array to fsig opcde yet but surely something must exist.

tab2pvs is the missing link
