Hi list,
I was wondering if one of you could help me with a patch I'm working on:
The patch (see attachment) attempts to implement a phase oscillation instrument with feedback. The output of a phasor~ (the carrier) is added to the output of an osc~ (the modulator) and the combined result is fed into a cos~ object.
This works perfectly.
However, when I try to feed the output of the cos~ object, multiplied by some value between 0 and 1, back into the chain somewhere and turn on audio processing, PD immediately segfaults ("Consistency check failed: signal_free").
So I guess I can't do this. Can anyone explain which obvious mistake I'm making here?

you have to have at least one sample delay when you do direct feedback with signals. my pd version doesn't segfault, just no sound is comeing.

Indeed, inserting a 1 ms delay seemed to do the trick. Thanks!
