In fof2 I read
   xform -- the formant frequency, i.e. freq of the sinusoid burst
   induced by each xfund impulse. This frequency can be fixed for each
   burst or can vary continuously (see ifmode). 

I can find no reference to ifmode on that page.

Also it says
    kgliss -- sets the end pitch of each grain relative to the initial
    pitch, in octaves. Thus kgliss = 2 means that the grain ends two
    octaves above its initial pitch, while kgliss = -5/3 has the grain
    ending a perfect major sixth below. Note: There are no optional
    parameters in fof2

But iskip is an optional parameter

This from the 4.16 manual:

ifmode (optional) – formant frequency mode. If zero, each sineburst
keeps the xform frequency it was launched with. If non-zero, each is
influenced by xform continuously. The default value is 0.

Re: optional parameters, iskip would seem to have been added since 4.16
and the manual wasn't updated.  Maybe the bit about "there are no
optional parameters" is to remind people that they always will have to
add a ",1" for what might be a relatively rarely used feature (i.e kgliss)?

Yours truly,
David

Hi,
Thanks for the reports,

Done, removed references to other types.

Done, committed new graph with changed title, I'm assung the random 
distribution is the same for both opcodes.

Looking at the sources, it seems the FOFS struct is written to 
accomodate both fof and fof2 (see H/ugens7.h and opcodes/ugens7.c) and 
the ifmode parameter is used for glissando on fof2 (so fof2 doesn't have 
an ifmode parameter, so references should be removed. However the code 
on a very quick glance looks very strange in line 135, can someone have 
a look?
I'll keep the manual as it is while someone can confirm.


Cheers,
Andrés
