such a thing as de-quantizing?

Howdy, techies - (I'm so NOT ONE!)...
QUESTION: can something digital be made to 'fake' analog?
What I mean is - can digital be made to work and be applied like a continuously-changing/automatically-adjusting to natural gradation?
Or - are the two simply incompatible?
Understand my question?

Good morning Peter!
I think we could better answer the question if you were to let us know what you are trying to do

Well... it's not music-related; but it seems to me to be similar, in theory... the difference between a drum machine and live drums - which can be variable.
I've designed a REAL-TIME calendar app. I made a paper mock up of it... then contacted a friend (former golfer buddy! you'd appreciate that) who is a web engineer.
It's based upon the lunar phases, which are constantly changing; but the app, obviously, is limited - so it seems, and is now - due to the digital calculations.
I'm due to have a Zoom Video Conference with him this evening, to discuss whether or not the app can either
1) be set to automatically re-adjust at a given start/re-set point;
2) or, be manually reset at any given time. (that would be a bit of a hassle, but better than it being WRONG.)
Thanks for the reply.

I see...
It would seem (without knowing more) that the important thing would be how to Trigger the readjustments
And what causes the Trigger to respond?
We can fake drums because we have the ability to Trigger a good number of nuanced hits
(Can't seem to Trigger "Dropped Sticks"
)
And can place those Triggers/Midi Notes anywhere in a straight timeline, as a drummer would do
If you aren't able to work on a straight timeline but instead need multiple timelines then I think you are jumping into Logarithms
Not an expert, just guessing...

Me neither... on the expert thing... but it SOUNDS like you're onto something...
"triggering the readjustments" might be the closest thing... and, I think I could make it work if it only re-aligned 12 times a year - at the 1st of each month.
More refinement than that would be 'way cooler'... but at least I'd be in the ballpark.
I could email you the link to the app - but it's out-of-sync currently, due to this digital issue. ARGH...
if I could just hit a 'reset' button.
Just like I wish my Zoom H4n had a 'make me sound like Alan Jackson' button.

I am really intrigued, because I have no clue what you guys are talking about.
How is a calendar connected to triggering MIDI drums?
What is real time?
Man, I am lost!

Okay if I "PM" you on this?
Later, though... my pizza needs to come outta the oven now - and it's about time!
My goal - is to take something that looks/seems to be complex and complicated, and - by making a single, working, graphic model (in an app);
make it such that an 8-year-old can easily understand it.

Yes - if it is not too much work to fill my gaps.

Self-made, freezer, or delivery?
It's DiGiorno, Man!... or, however it's spelt.

When you need to reset this calendar as it has drifted out of synch - how do you know what to correct it to.
i.e.
1 is there an algorithm to calculate that ?
or
2. do you just look the correct value up in a table
or
3. Is it directly observed e.g. measuring where the moon/planers/sun is directly at a certain time

It sounds to me like you're trying to track a function of planetary orbits and such - which will not be cleanly divisible by any combination of whole numbers. You will need a 'reset' of some kind to avoid the rounding errors that accrue when running an equation that approximates the real motion of the moon, sun, etc.
I have some clocks at home with very accurate quartz timing crystals. Good for weeks, months, or longer but eventually get out of sync with "real" time. The other clocks are reset each night by sync'ing with a satellite feed. That's their solution to the 'losing time' problem. How you sync up (and with what kind of database?!) will be the issue to make your lunar calendar perpetual.
Am I close to understanding the problem?

It could be as easy as the 3rd option.
We'll see.
