It can't be said often enough - read the manual!

I just now - today - realized that the CP-251 Sample and Hold has two different outputs. I've been running output 1 through the lag processor to get a "smoothed" sample and hold for years. I just realized that output 2 gives a "smoothed" sample and hold. Ugh!!

I'm with you. I find it most helpful to read, turn knobs, read again, and repeat. Most manuals contain too much info to take it all in at once.

The manuals for these are great and worth reading and re-reading!

You'd think there would be some kind of a hint on the panel....
...just sayin'.....

After I saw this post, I reread the CP-251 manual and found at least 1 thing new and interesting:
The Lowpass Filter cutoff on the smoothed S&H output is proportional to the LFO speed, so you can send CV to the LFO to control the smoothing Filter!
I have no idea how I will use this information, but it is interesting and something new to experiment with no less.
Another thing is the Noise output is 1.2vPP, which seems like a very low range for a Sample and Hold. I bet you could patch a better noise source into there and get different resulting output too. ...or run the noise out to a lowpass filter and back to the S&H to limit the range of noise and have CV control over that effect by controlling the filter.

This is actually pretty important, as far as I'm concerned. That means your smoothed Sample and Hold will always be smooth at every sampling rate. I tried to duplicate the smoothed sample and hold from this thing, and my version is very "not smooth" at very low sampling rate.

I guess an external LFO could be used and the internal one's rate would dictate the filtering frequency.

Oh yeah, that way you can vary how smooth the smoothed sample and hold is at different frequencies.
I also learned a couple weeks ago that you can run audio into the input of the sample and hold, clock the sample and hold with a much faster LFO, and the output will be a sample rate reducer (or nyquist aliaser) when you slow down the external LFO.

Makes sense indeed.
So much to try
