I found this comment from someone working to make a Twin Peaks with a v3 chip:
If anyone is building this with the new TapLFO 3D chip there's some minor changes that needs to be made.
"1.Remove Crystal and the two 22p caps next to it.
2.Remove 10k on Pin 4
3.Remove 10k on Pin 8
And since the new chip has 16 waveforms (2x8), you can put an SPST switch on pin 3 to ground to alternate between the two sets."
This based on a vero version of the circuit, but a couple comments suggest successful builds with it - http://tagboardeffects.blogspot.com/2015/10/twin-peaks-tap-tempo-tremolo.html
