Freeze Overdub/layer?
Quite a few reverb plugins have freeze feature. Someone asked recently whether there is anything on iOS that lets you layer/overdub freezes … apparently there is a strymon pedal that lets you add freezes layers.

Comments
The pedal in question is Strymon BigSky. I think the mode is maybe called Infinite Sustain.
For this use-case, the person is really looking for a single plugin that can essentially overdub freeze layers.
Lots of reverbs can do a static freeze but none that I have seen allow you to add to a freeze.
Do you have it? Someone said elsewhere that the freeze can be played over but not added to. Perhaps they were mistaken.
Once you have that freeze, can you layer another freeze on top of it, and then again, etc
Any chance you could do a short demo of infinite layering one note at a time to build a frozen 3 note chord than play something over that?
What the person who asked about this wants to do is freeze a note he plays on violin then add another frozen note and so on until he has built up a chord over which he can solo over
@offbrands : thanks for the examples!
Nice demo @offbrands and your descirption is spot on, i.e. it basically doesn't apply decay to whatever is in the delay line buffers when freeze is on.
For a nice ambient effect, I'd usually run a delay or another reverb after SploshBox when using freeze mode as when freeze is on, you only get the dry signal.
I am the one who is looking to layer multiple notes on my cello and freeze them.

Using the tail freeze function and then playing new notes to freeze again isn’t ideal, because the previously recorded frozen notes fade as I add new ones.
I found a solution with Cascade:
Record the chords with the infinite loop (♾️), then “print” them with the freeze function (❄️). Then stop Infinite.
So I can play on top, add notes if I want, or make a new Pad later on.😎
Here a quick demo.
The 2nd channel of the reveb when using the Freeze function is not set properly but it can give you an idea.
