Thank you everyone for the suggestions and interactions. I wound up going with the solution above. It works perfectly.

I'll post the composition when it is done. I'm doing some things with microsound and prime numbers.

Yeah, a square wave would work.

However, the automation thing works better for my purposes.

I would use two sends to route the signal to two buses. Then, put a tremolo effect on each of the bus’s effect bin.  Use a Tremolo that allows for a very specific modulation wave (In your case, 50% duty cycle a square wave set at 1/128th). 

Meldaproduction’s MtremoloMB comes to mind.  MtremoloMB’s  modulation source be any waveform you like.  This modulator can also be synced to tempo.

I had thought of this basic idea but I did not have a way to do it. Thanks!

That will not work for the purpose of cutting into a sine wave. Thanks anyhow.

Sorry, I should have been more specific. I want to select alternating 128th notes all at the same time and move them to another track. I already understand the snap grid unless there is some functionality there that I missed that is relevant.

I am doing an audio project where I'm cutting into sine waves and splitting them between stereo tracks for the purposes of a type of granular synthesis.

I want to know if there is a way to select alternating 128th notes in an audio track. Otherwise I'll be doing this for days and possibly weeks on end selecting them by hand.
