[PD] stereo vibrato-delay

[Frank Barknecht]

I have a simple looking problem building a vibrato delay. The attached
patch should add a vibrato to both channels of a stereo signal. But only
the right channel gets vibrato, the left stays unchanged. This must be a
stupid mistake on my side, but I just don't see it.

Does anyone know, what I am doing wrong?
