Package arrived today. Thanks Ian. First impression of the sine pie is the audio equivalent of putting on glasses that you didn’t even know you needed. Cymbals are more detailed, vocals more nuanced, the bass and overall pace both have more drive. A big thumbs up and an even bigger smile.
Thanks DDDAC, that's a correct answer.
SinePi works for all clock input, both sine and square, both AC and DC. Amplitude range from 0.5V to 5V Vpp.
That makes the application pretty fixable.

Ian
Thanks stephen1212b for the update. I'm really glad that you like my SinePi. It was carefully designed and that was what I was looking for.
Enjoy the music.

Ian
Ian could you please confirm the block signal flow of the sine pi?
Is the relay pre, post squaring circuit or both?
Does the clock active pin 1 from clock position 1 activate the relay? I am hoping to find a way to manually select between two clocks of the same time base just for testing and comparison purposes.
I am temporarily driving a twisted pear chronus which wants the 44.1 k time base in position 1 and the 48 k time base in position 2. Everything working well with just one clock connected but I wanted to verify operation before connecting second time base, also wondering where in the signal path is the resister r2 that is removed to allow one sine and one square clock? Would removing this resister result in the squared sine outputting to one position and the local clock outputting to the second position?

Relay is before the squarer. The relay is driven by Pin1 of XO2 socket. So, only one frequency is select at a time.
"Would removing this resister result in the squared sine outputting to one position and the local clock outputting to the second position?"
Yes, In this case, sine output will go to XO2 socket, XO1 socket will be the local XO.
SinePi was designed to work with FifoPi or McDualXO logic, so I can not guarantee it works for other applications.

Thanks, Ian /DDDAC /Folks.
If there is an output option from the Oscillator vendor, is any preferrable output that best matches with SinePi (since SinePi is designed for Sine-to-square and is acceptable for both types of output).
Output option: Sine /Square
Amplitude around: 1.x
@ calebwong
If you have the options to chose, I would suggest use the XO with the sine output if you have a SinePi in your system.
The reason could be that for any XOs square output, they must have a built-in sine to square converter, but the performance may not as good as the SinePi, unless otherwise.

It seems likely that with a first generation WTMC with the built in squarer, it would be possible to remove the squarer IC and pass the sine wave directly to the output and on to SinePi. Might be something I try in the future for the 48k multiples.
