Yes, the NE5517. But it's more like the 13700: not exactly a clone (see the
equiv. circuit diagrams at the sheets) but a improoved version, with
constant impedance buffers at the output (it helps to avoid changes of
output offset voltages that can cause audible "bumps" as CV varies). Yes,
the 13700 does have it too, but the Philips solution seems to be better. 

It appears that Philips tried to bring the best of both the 13600 and 13700
to their chip. The NE5517's are OK for audio, but I haven't tried a VCO or
other synth circuit with them yet.
