Subject[Csnd] how to turn off flanger, moogladder echos
This produces some interesting sounds,
but sometimes I would really like them to quiet down awhile:
---
asig poscil 1, p4, gicosy
af = sqrt((1 + asig)/8)
a1 flanger aLeft, af * 0.05, kfb
a2 flanger a1/2 + aRight, af * 0.02, kfb
ares moogladder a1, kfr, kfb
ares2 moogladder a2, 3 * kfr/2 , kfb
outs ares2 + aLeft , ares + aRight
----
How to find values of kfr & kfb for damping out the wranging noises?

Would it be really silly to suggest a minimal volume fade out?

That's not at all silly -- but I'm trying to control things with two foot pedals and a midi keyboard.

The sound is running and changing on its own in an always-on instrument, long after the signal from the original note has turned off. I like that feature, but not forever...

So what is the main problem? That you get abrupt changes of the filter
frequency, while the note is still holding or that you get weird effects
when the note is somehow muted for a moment?

If it's harsh changes, have you tried port/portk. If it is weird effects
on muting, you could try some kind of port or control signal lowpass
filtering on the overall volume.

The intended effect -- and the problem, when it goes on too long -- is continuing weird sounds when the incoming audio (aLeft and aRight) goes to zero.

I was hoping that zeroing the feedback in the flangers would cause a shutoff, but feeding some of the first flanger's output into the second may have kept that from mattering... or something in the moogladders (which are doing some lowpass filtering; maybe I haven't set the frequency kfr low enough... ?

Thanks for efforts to help -- but my mistake; the problem was probably not in the twisted code I posted.

aLeft and aRight were coming in from a channel which I wasn't clearing.

Csound: A Sound and Music Computing System sayeth: "The bus signal can feed other instruments as required. Once all destinations have read the bus, we need to clear it. This is very important, because as the signals are summed into it, the bus will accumulate and grow each k-cycle, if left uncleared."

Oops.

Putting the outlettas too early in a previous instrument.
They needed to go after these lines (& now the sounds end when they should):

...
if lastcycle() == 1 then
aenv = 0                ;  zeros out "OutL" & "OutR" at the end of notes
rerun:
itom = i(ktom)
        reinit rerun
                            ; (Logs this note when we know the length)
S_event sprintf "i %d %.2f %.2f %d %d\n", 21, itim, itom, p4, p5
if (itom ==0) goto noprint
fprints "score.sco", S_event
noprint:
endif
outleta "OutL",  a1 * aenv
outleta "OutR", a2 * aenv
endin
