Hi All,

I think one bug I found in wguide2 is that I think the following code:

    p->xdel1cod = (XINARG1) ? 1 : 0;
    p->xdel2cod = (XINARG2) ? 1 : 0;

should have been:

    p->xdel1cod = (XINARG2) ? 1 : 0;
    p->xdel2cod = (XINARG3) ? 1 : 0;

Also:

if (p->xdel2cod != p->xdel2cod)

should have been checking:

if (p->xdel1cod != p->xdel2cod)

The test was passing regardless, then because the check later in the
code was only looking at xdel1cod, which was always a-rate since it
was looking at the first arg, the wrong branch of code in the wguide2
function was always being used, the one assuming the frequency values
for the delay lines were coming in as an a-rate vector.  So, that lead
to reading from unknown memory, hence the bad values on different
ksmps and why things sounded correct on ksmps=1 (didn't increment the
pointer past the scalar value).

This fixes up this aspect of the opcode and has been checked in.

Jean Piche noted to me that that feedback values are limited to low
values, such that values above .25 or so cause the opcode to go
unstable.  From my own testing, it seems that the combined values of
the feedbacks can not be above .5 in total.  Could someone check out
the flowgraph diagram in the manual for wguide2 and verify that that
is what the limit should be? I've played with the opcode only a little
feeding in a number of different values and it seems to be working for
values as long as I keep to the .5 total rule.  If this is correct
behavior, then I think the manual could use an update on this.

If others could test this fix out, that'd be great.

Thanks!
steven
