Cool, Ian. I figured it was the case.
It's a nice build. I like the idea of the multiplier switch. I assume you used the "Next multiplier" input. Does it somehow automatically switch back to the original tempo, or do you have to cycle through?
Also, I don't remember what Taylor specs for the cap that goes across the output side of the opamp (330p maybe?). Upping that reduces ticking, but also softens the waveshapes. I think I ended up at 1n in my build, and 1n5 was the upper limit of usefulness.
If you ever want to make a non-tap version, I have a some VCLFO9D (precursor to the Taplfo), and an etchable and easy to build single-sided board that you could use. It's exactly like the Taplfo, but no tap.
