editUSB keyboard not recognised by boot CD? Would PS/2 be different?
editI made a bootable USB disk version of "Hiren's Boot CD" and it is recognised by the BIOS and appears in the list of drives. The problem is that it doesn't respond to my USB keyboard. I'm wondering whether it's reasonable to think that it would respond to a PS/2 keyboard instead. The BIOS responds to my USB keyboard so I figure there's no reason that the "boot CD" shouldn't either? If the BIOS doesn't need any drivers to talk to the keyboard then neither should the boot CD, right? In which case I'd have to conclude that the boot CD hangs after loading. --145.255.246.8 (talk) 00:23, 4 September 2017 (UTC)
- There's a fair chance a PS/2 keyboard would work, but if I were you I'd make sure to turn on any legacy USB keyboard etc options in the BIOS before worrying about that. You shouldn't assume the keyboard working in BIOS will mean it will work on other OSes. If it's actually EFI not BIOS, your assumption about a lack of drivers isn't even necessarily correct.

- If you have enabled any legacy USB support etc in the BIOS, see [1] for some more suggestions. Based on that, I'd try a cold boot and also disconnecting any unneeded peripherals if enabling legacy USB isn't enough. Nil Einne (talk) 14:16, 4 September 2017 (UTC)
- To add to the above excellent advice, if you are going to be mucking about with systems that have PS/2 ports, it might be worthwhile to just keep a PS/2 keyboard on hand. $17.75 on Amazon.[2] a PS/2 mouse will cost you another $6.25.[3] I was fixing an old Dell a while back, and found that it worked great with a USB mouse and keyboard, no drivers needed, in Linux and Windows, but I could not change the BIOS settings without a PS/2 keyboard. --Guy Macon (talk) 21:20, 4 September 2017 (UTC)

- Note: The 5 volts needs to be present on the jack, anyway if PS/2 or USB. When using USB, the internal USB bridge and USB hub need to be supported by the operating system. Do not use and USB3.x for HID devices like mouse and keyboard when USB2.x or lower are present. Some M/Bs have a combined PS/2 and two USB jacks in one printed connector. Use this ports first. Check BIOS for "USB legacy support" option. Toggle this setting. A dual mode HID comes with an passive USB-PS/2 adapter. Just 4 wires an a shield connection installed. See articles. There is no specification, how to adapt the CLK and DATA from PS/2 to USB D+ and D-. Same chip designers most likely use identical adapters, no matter if green or violet. --Hans Haase (有问题吗) 12:59, 5 September 2017 (UTC)
Video info update during sharing
editWhen one renames one's own YouTube video, there appears to be some delay in its info update when sharing through Facebook. While on YT itself the info updates almost instantly, I waited for about one day and when clicked to share through Facebook, the popup sharing window still displays the old title and description. What to do and how long does it take? 212.180.235.46 (talk) 07:13, 4 September 2017 (UTC)
- Edit the message on facebook, and if that doesn't work remove it and post it again. I don't think FB is going to check if the name of a YT video has changed. (((The Quixotic Potato))) (talk) 07:41, 4 September 2017 (UTC)
- Turns out it's just in the preview of the popup sharing window and after sharing, the updated title is shown correctly. 212.180.235.46 (talk) 09:42, 4 September 2017 (UTC)
I'm looking for a comprehensive database of digitized Mellotron samples, especially from the M300 series. I've checked out a lot of sites but it seems that they're always in some weird proprietary format (and in any case, the listings are generally very sparse). Can't seem to locate much of anything in a standard container (wav, mp3, webm, etc). 73.232.241.1 (talk) 11:24, 4 September 2017 (UTC)
- Not really free but definitely good if you can ignore the noise of someone singing. Blooteuth (talk) 13:38, 5 September 2017 (UTC)
- Yeah, I love those old videos! What I'm really wanting to do though is write a program that allows you to play/record songs using samples taken from an actual machine. 73.232.241.1 (talk) 20:47, 5 September 2017 (UTC)
- Good luck with your worthy project. The Mellotron's reported polyphonic aftertouch will be a challenge. Blooteuth (talk) 22:09, 5 September 2017 (UTC)
- Yeah I was thinking about that. No straightforward way to emulate it with a computer keyboard (too bad they don't detect pressure). I was wondering if some clever combination/interpretation of key presses might do the trick, but so far haven't come up with any good ideas for that just yet... 73.232.241.1 (talk) 22:33, 5 September 2017 (UTC)

- What's this? Or am I missing something? --jpgordon𝄢𝄆 𝄐𝄇 22:11, 5 September 2017 (UTC)
- God love you man, thanks so much! That's exactly what I was looking for. 73.232.241.1 (talk) 22:33, 5 September 2017 (UTC)
- Happy to help. That was just the first Google result searching for "mellotron samples". --jpgordon𝄢𝄆 𝄐𝄇 23:49, 5 September 2017 (UTC)
- I don't generally like to use Google (just on principle) but I have to admit that I may be getting the short end of the stick in search results because of that. I might need to reconsider my choice there...73.232.241.1 (talk) 23:57, 5 September 2017 (UTC)
- Well I can't say what it was before this question, but it's also currently the first search term for Bing and DuckGoGo. Nil Einne (talk) 15:31, 6 September 2017 (UTC)
