The #1 rule is: Be respectful of others, of the site, and of the community as a whole.
2. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^], or to discussion your programming problem in depth use the programming forums[^]. We encourage technical discussion, but this is a general discussion forum, not a programming Q&A forum. Posts will be moved or deleted if they fit better elsewhere.
3. No sys-admin, networking, "how do I setup XYZ" questions. For those use the SysAdmin[^] or Hardware and Devices[^] forums.
4. No politics (including enviro-politics[^]), no sex, no religion. This is a community for software development. There are plenty of other sites that are far more appropriate for these discussions.

(nobody actually said that. probably ever)
Looping MIDI performances creates a number of interesting challenges. For starters, you have to count the number of times note offs and note ons happen so that the note offs you've captured in a loop do not cut the notes you're actively playing short.
Secondly, you have to insert note offs for any note that's currently being held down when the loop is finalized *but* you avoid sending the actual note offs, you just insert them at the end of the loop for the next time around.
Finally, you have to quantize the loop lengths so you don't have to have the timing of a 12-year old gamer to actually play the thing.
And and there's gotchas, like not capturing MIDI reset messages, or pitch bend messages.
All that is ignoring the user interface, where you have to set up which midi signals you use to indicate the start and stop of a loop, and how to navigate multiple loops. It gets hairy fast.
It's an interesting challenge though - one I solved ages ago purely in software as a VST plugin but I've long since lost that code.

She's been having issues with low blood pressure causing fainting, and last night she started having chest pain. Took her to the hospital around 2:30 PM, and went home an hour or so later to let the dog out. I got a call from her a bit ago, and she's been admitted for monitoring overnight due to damage on her heart and elevated cardiac enzymes (at 58, normal is < 10). The doctor is going to do a cardiac catheterization in the morning, and go from there.

I recently bought a new 14TB disk drive to put in my new 4-disk enclosure (no raid or anything special, just a simple enclosure to save power strips) connected to my file server via 6gb eSATA.
I liked the way it performed so went back to buy another one only to find it was out of stock but they offered a "renewed" version of the same disk for $10 less. I decided against this as disk life seemed important and I don't care how much they polished the case, the disk itself had obviously done some amount of spinning before it was "renewed".
Anyone got any definite knowledge or even vague opinions about this?
- I would love to change the world, but they won’t give me the source code.

Use the renewed one as a backup / for backups of the new one (or vise versa).

$10 off on a $300 dollar HDD to get a used drive? I'll give it a miss.

HDDs are assembled in a clean room (How it's made - Western Digital Hard Disk Drives - YouTube), because even dust particles can cause damage to the platters or R/W heads. There is no guarantee that the "renewal" work was performed to the same standard.
Note that some HDD manufacturers will sell refurbished drives. These are typically repaired drives that have been tested by the manufacturer to meet the same standards as new drives, and are typically sold at a significant discount. Going to Western Digital's website, a MyCloud Home 8TB lists for US $299, while a refurbished device lists for US $199.
Personally, given the relatively low price/TB of new HDDs, I would not risk my data on a drive that has already failed once.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

^ This.
Why else does anyone return a drive?
It's a ticking timebomb. I would not use a drive for anything important. That includes using it as a backup drive, as someone above suggested. Why would you back up anything on a drive you'd have less trust in than a drive for your "live" data??
Unless it's purely as an additional backup set.

Sadly, my old NAS fried a disk port, and that fried a disk, or a disk fried itself and that fried the disk port - but since Seagate made all the disks and the NAS itself, it's a moot point which did which.
Certainly the disk from port 2 is dead, and if I plug anything into port 2 the whole NAS locks up solid. And somehow, that destroyed the whole volume at the same time so all my info is toast. Never mind, I have the important stuff on offline archives, but I've lost all the JPG, MP3, and MP4 I loaded on from phones, CD's and DVDs over the years.
So, I've replaced the disk with an identical one to keep them the same, and bought a new NAS - QNAP TS453 this time. It's currently building the RAID volume which'll be a while longer as 16TB of disks is a time consuming process even at 6Gb/sec.
But test writes even while it's doing that show it's about 4 times faster write speed than the Seagate, and that should improve once the volume is complete.
And it supports SMB3 so Windows likes it!
But it can do other things: LDX and Docker containers ... including SQL Server as supplied in Developer Edition 2019 by Microsoft. 
That could be well worth putting on ... anyone got experience loading a docker SQL/Linux combo? (I know, I know - linux is the devil's OS but I don't have to touch it once it's running and it'll export it from my dev PC).

I have a 9 year old Synology NAS with 4TB of mirrored drives. In the last couple years, I've moved most stuff to the cloud and archived the remainder to external USB drives. When the NAS dies - I'll unplug it and forget it. Life is too short to manage home networks.

FTFY.

Yep. 8Mb/s upload vs 200+MB/s write speed? Not a contest.
Even with the Seagate, I got 35MB/s writes.

To each their own. I analyzed my usage and decided the cloud was a better choice.
Just curious… what kind of big data files are you transferring so frequently that makes local network storage so important.

The cynic in me wants to say "well there's your problem right there".
Maybe it's just my bad luck, but all the Seagate drives I've ever owned are dead. I tend to only buy WD, and of all WD drives that are no longer in service, it's because their low capacity doesn't make them worth using anymore, not because they died. They got retired still going strong.
I was even given an old system from work a good while back. 4 Seagate drives...2 were dead, and another one couldn't even complete a format request. My bias is entirely based on my own experience. YMMV.

My experience matches yours. Seagate drives fail when they're 18 months old or the data on them becomes critical to your job, whichever comes first. We have a couple RAID arrays originally built using Seagate drives but are now populated with Western Digital.

What RAID configuration were you using?

RAID 5. I suspect a major glitch overwrote whatever the box was using for volume management and trashed it across the all four disks.
RAID 5 has been good to me up to now - I've had HDD's go down on me before and 24 hours later I'm back with a replacement bought, hot-swapped, and rebuilt without any data loss or even access interruption.

I have not. The last NAS I had was gas petrol powered.

Is there any tool out there that can take two MP3 files, and compare the audio portion of it (only) to determine whether it's the same content or not? That is, if you have the same file that has been copied and then had its ID3 tags or embedded images modified - is there something that could tell me they are still, essentially, "the same"...?
Anything using hashes on the file as a whole is obviously not a contender.
(Way) more complex scenario: How about comparing two files, but also ignoring the encoding bit rate? That is, if it's the same track, but one's been encoded at 128kbps vs another at 320kbps - then I'd want to get rid of the lower-bitrate version...I believe something like MusicBrainz could do that sort of thing - as I understand it, it "listens" to the audio regardless of encoding and tries to identify what it is...but it's not exactly suited for my purposes (comparing files in bulk). But I have to think because this exists, it is technically possible...so what could be used automate this and organize the results in a way that makes sense?

Same "content"? Do a voice to text of the files; then compare the text. Probably need to run the import at normal speed, or less.

You might like this if you have some mp3's on your PC you like to play (or like to play along with).
It's an MS sample app for UWP Audio Creation. You can just run it from VS.
The first example lets you load a sound file and alter the speed; faster or slower.

Wait, no. No audio processor can go that low.
