sumgai you are in great shape man! Spot on 0,1,2 file descriptors.
in bash (Linux/BSD/Unix) the way to discard stderr while redirecting stderr is
% ./write_test 2>&1 1>/dev/null
Zorin OS?? is that a paid version of Ubuntu?

Zorin OS?? is that a paid version of Ubuntu? Derivative of Ubuntu 20.4LTS, yes. Paid, no. Actually, there is a paid version, called "Pro". I'm using "Core", one of the free versions, and I don't see any reason to upgrade from that. I'd been using Ubuntu since 14.04, because that's what Dell said would run on my laptop. After upgrading to each successive LTS version, I literally stumbled on a website where someone said that Zorin 16 was the bee's knees. I took a chance, and haven't looked back since. zorin.com - try it, you'll like it! HTH sumgai

I went to Linux Mint when Windows 7 went EOL. I never much liked anything Microsoft did after Windows 7, but since I still wanted to use the Internet without reverting back to the old Dodge City days I did the same thing and switched.
Actually, I dual booted the machine. I still have Windows 7 with a disabled network adapter...and all my software that works still intact. As long as you have a free partition or hard drive, I believe any Linux distro will allow booting as long as Windows is installed first...but I digress..
SG- What is the device support like in Zorin?

When I said “class D watts are different from analog”, it was maybe a bit lazy. First of course class D amps are technically analog, so I guess probably more like as opposed to more traditional class A or class A/B. But also it’s kind of that same thing we’ve had for years where you have to know exactly what the manufacturer (or marketing department) means by “watt”. Is that peak-to-peak or RMS? Is it like total available “surge” power that it can supply every once in a while without exploding, or is it maximum continuous average that it can handle before thermal protection kicks in? Perhaps more importantly, the question is exactly how much distortion was allowed in the calculation. We’ve known for years that the wattage rating on a car stereo amplifier probably has higher THD tolerance than say a hi-fi amplifier, but that consumer stereo equipment is still probably a bit looser in its spec than a reference amp for studio use, and from what I’ve seen and read, it seems like most of the people selling class D amp allow for quite a bit more distortion than other amps. But kind of almost conversely, I think that actual tube amps are specified kind of low. That is, their ratings are often quoted at a level of THD that very few guitarists actually shoot for. Most of what we like about tube amps is the distortion. Even a relatively clean sound often actually has a lot more rounding of peaks than we’d ever accept in a hi-fi or PA. If we start talking about actual crunch, overdrive, and especially when we talk about high gain metal type sounds, we end up way past that lowish THD spec pretty quick. The RMS average of a sine wave with a given peak level (a proxy for a signal that just barely reaches our limit) is half the square root of 2 times the RMS of a square wave with the same peaks (which is about as distorted as you can get*), which means the square wave’s average is ~1.4 times that of the sine. BUT the saturation curve gets noticeably curvy (THD goes beyond spec) somewhere around 6db down from the actual limit. So, that dimed 100W Marshall or Mesa or 5150 could well be pushing over 200w RMS of raging brutal metal madness into the speakers... Or something like that. *Yes, we're aware that real amps can't actually give us square waves, but it doesn't much change the basic point.
Great info, but does the ear perceive any average , or only momentary sensing ? Also you imply that distorted sounds are more of the square type?

SG- What is the device support like in Zorin? I honestly can't say, as all I'm using is one 4-year-old laptop, so my personal experience is limited. But as luck would have it, Zorin is derived from Ubuntu, and Ubuntu comes from the Debian school of how to make Linux sit up and dance, no matter what hardware is on the table. From that, I'd have to say that the device support should be top-notch. (All the usual disclaimers, etc, etc.) HTH sumgai

From my experience, open source is open source. Based on what I paid for it I can't b h, but it can be a slog to get apps and devices to play nice. I also have to say I miss the GUI's. I remember command line back in the old DOS days, but I can't say I enjoyed learning it all over again with Linux. That's why I left the old Windows 7 intact, just network kneecapped. Most of my old Windows stuff isn't available in Linux, and my M-Audio LT1010 is still a mystery to Linux... I imagine I could spend more time on Google and fix this...but the dual boot works without burning the few brain cells I have left to resolve the issues... If all you're doing is e-mail and browsing I would bet any Linux distro will work. The more specialized you want the configuration figure on fixing it by yourself. HTC1

Guys, I'm handicapped just now, trying to work with two cataract-removed eyeballs. Sure, they put in new lenses, but they don't cure my (mild) astigmatism, so I'm not focusing very well at all. Let me put your questions on the back burner for a few days, then I should be able to work without having to zoom the screen to 300%.... and it's still fuzzy. sumgai

The problem I have is the computer has two sound cards. I use the 1010LT for input when recording, and I have an X-Fi Titanium for playback and listening to music. The 1010LT goes to a small Phonic mixer, two amps and the stereo amp, where the X-Fi only goes to the stereo. Windows would require a bit of tweaking to start with, but once configured it's only been a matter of selecting which adapter in the app or OS and go...for years. Linux has been a bit more of a battle. I'll take a closer look at the link in your post. Still recovering from the last time I tried to get it to work... Either way, there is no Linux version of the M-Audio control panel, and that was critical in getting the MIDI to work without chewing through your ankles in the process. After 2 years with Linux I can't say I hate it. It's a lot like the old DOS or NT days. Install a device or app and cross your fingers on startup that it will work. Linux Mint has been extremely stable. It has some quirks, but if you don't ask it to go out of the open source realm it's great. It strikes me as a cross between XP and Vista...it does what it does very well, until you ask it to do something it's never done before or utilize a device not contained within the 3x5 card listing of supported devices...

so what's better in Zorin vs plain kubuntu or ubuntu studio? First off, the whole reason to go to Linux was because Intel and Microsoft teamed up to force everyone to upgrade their hardware, should they need to run newer versions of software. Vast swaths of such were written to run only on the latest version of Windows, and that OS was written to run only the latest hardware. Grrrr! There outta be a law against that kind of thing! And of course, that had to include drivers. Under Win7, my old laptop had a veritable deluge of touchpad options. On the new laptop, with the 8th gen CPU, Win7 isn't supposed to be used. In fact, it's not supposed to be even able to run at all. But thanks to the internet, I got most things working, with only a couple of exceptions. But when I discovered that a valid touchpad driver was not forthcoming from any manufacturer, that tore it up and tied it off - time to move. Ubuntu restored my touchpad usability. When I boot up in Linux, I have full control. When I create a VM in VirtualBox, I can either allow VBox to pass 'mouse' control to Windows, or I can keep it under the control of Ubuntu, and configure that to pass only what I want to go to the VM. Voila, erratic cursor movement while typing is a thing of the past. Now, I'm not against doing a little typing, I'm still pretty proficient at it. But the Ubuntu GUI was, and still is, an absolute train wreck. I could say the same several other Linux variants, but of course, I've not tried them all, so.... Along comes Zorin, and Good Gawd Almighty, this is what Linus Torvalds should've done in the first place!!!!! Finally, someone just sat down and figured out that Linux for the average user was never gonna take off, unless it looked and felt like Windows - any version of Windows, all the way back to NT 4.0.... and to quote Captain Picard, he/they "made it so". Don't get me wrong, it's still Linux, so it isn't real Windows, but when you do things like ask for Task Manager, a very near clone comes right up. Network configuration? Not quite identical to Windows 7 (or Vista), but close enough that you don't need to hit F1 for help. I call that a Good Thing. I find that I can do Files/Folders/Disk Management about as easily on either Linux or within the Vbox instance of Win7. In fact, I have Win10 mounted only because of a client that insists on using Office 2019, and that's one of those "requires Win10" bugs "features" that we all so dearly love. (FWIW, I'm waiting for the Green Earth crowd to go on the warpath about planned obsolescence, and all the forced recycling of perfectly good gear just to "keep up with the Joneses.") Security? Glad you asked - on my rig, Win10 has no outside access, period. It barks, cries, whines, pisses and moans every time I fire it up, but no one has yet shown me the law that says I have to let MS monitor all of my activity, etc. It's bad enough with Win7, but there I managed to firewall that OS down pretty tightly. Which is another reason I went with Linux in the first place. Firewalling something is a veritable PITA, but I can fine-tune it to do what I want. In short, Windows anything (firewall, Defender, what-have-you) is a waste of time. It may be easy, but not very many people stop to think "Is this too easy? Am I missing something here?", and Lo & Behold, MS wrote so many exceptions to your desired blockages that you might as well have not bothered in the first place. (Disassemble inet.dll, and look at the list of addresses that Windows will access, regardless of your firewall (and any 3rd party firewall you might install), or the HOSTS file. Stated simply, you can't win, you can't break even, and you can't quit.... until you move on to Linux. Oh, and of course, you can replace the desktop with your choice of environment. I just happen to like the way Win7 looks and feels. At that, I could still go back to WinXP without skipping a heartbeat. The usual screwball implementations of KDE and/or Gnome.... not a chance. tl;dr: Security first, then usability second. I already had viable security with Ubuntu, I only moved to Zorin for the properly developed look-and-feel of a Windows desktop. HTH sumgai

hahah at 17 I had never seen a computer in my village, so at Univ, I thought that SunOS was the "normal" operating system. Since then I always went for anything that looked like BSD Unix, I tried to avoid SysV or Linux for years , but I cannot pretend I can survive only on FreeBSD anymore. So linux it is... (with the good and bad).
About Windows, I have no clue, barely have touched anything MSoft, ever, but I do know that since recently MSoft is strong advocate of Linux/PostgreSQL (on their Azure offerings) which was a surprise. Many top hackers were employed by MSoft, a big surprise.

Katana sounds very nice! How does it compare to the Catalyst? I assume Line6 put those out specifically to compete with the Katana?

Oh yeah, this thread did derail itself, and without any help from gumbo - imagine that! As rroc just brought it back on track, I'll file an update in a separate thread in a moment. I won't move any of the above posts, in my new thread, I'll simply link back here. sumgai

rroc, Don't worry, it happens all the time in here (in The NutzHouse). As to the comparison, I'm unqualified to help you on that score. Perhaps pyrroz, or another member, can give you the low-down on that front. HTH sumgai

Hi , I returned this amp. It is nice if you want to play clean along youtube backing tracks. The end. The software sucks, the amp is so much worse than me-25. This brown amp sounds bad.
