I have error when try to execute this csd. It says "input arg 'ifreqb' used before defined, line 17:"

Whats wrong? Thanks.

yes you can use init in the body of the instrument. this sets variables
during the initialization.
you can have a look here, if you want further explanations:

well, in this case you don't need any init, but you must read both
values in one score line:


0dbfs = 4
instr 1
ifreqa = cpsoct(p4)
ifreqb = cpsoct(p5)
kfreqm line ifreqa,p3,ifreqb
aout oscili 1,kfreqm,1
out aout
endin


f 1 0 16384 9 1 1 90
i1 0 4 8.0 8.7



at least this is the easiest way to do it, i think.

hello, 

if I get you right, you want to have a glissando from the frequency of the previous note to the new one?

then I sugest you should use one global variable to store the value of the old frequency.  Like:








sr = 44100
kr = 4410
ksmps = 10
nchnls = 1
0dbfs = 4


giOldfreq init 20 ; 0 is probably not a good choice for frequency


instr 1

ifreqa        =       giOldfreq
ifreqb         =        cpsoct (p4)
kfreqm                line ifreqa,p3,ifreqb

giOldfreq=ifreqb ; now when line parameters are initialized, you can store the current value so next time it will be the "old" value

kdeclick linen 0dbfs, 0.01,p3,0.01

aout                oscil 1,kfreqm,1
                        out aout*kdeclick
endin




f 1 0 16384 9 1 1 90


i1 0 2 8.0
i1 + 2 8.7
i1 + 2 9.7
i1 + 2 3.0
