Meeting In The Air Southern Gospel on Piano

  


Meeting In The Air MIDI File

     This marks the 2nd new Southern Gospel song posted since re-starting this blog.  Meeting In The Air is an old old favorite.  I loved to sing this in church when I was a kid.  It's one of the songs I can clearly remember from church, from Uncle Freil playing, and from playing it myself.

    The song's original copyright was in 1925, and is currently under the Public Domain.  It was written by Mae Taylor Roberts.  According to Hymnary, the copyright notice originally contained this offer:  "This song may be had in sheet music at 25 cents a copy. Order from Mrs. Mae T. Roberts, 1554, East Washington, Pasadena, California."  Since that was nearly a century ago, I sincerely doubt she's still honoring her offer.
    I've looked for more information or songs from Mae Taylor Roberts, but couldn't find anything beyond the small amount Hymnary has.  If you'd like the lyrics, Hymnary offers 3 verses plus chorus.  I've seen it in the past with 4 verses, but usually consider Hymnary to be the most reliable source of hymn information.

    Speaking of verses, I took the road less traveled this time.  Most of the time, I'll do two or three verses with a chorus between each. This time around, I had an example to follow.  I recently found several decades-old videos of my uncle Freil playing.  This was one of the songs, so I had the rare opportunity to compare my version to his.  For his version of the song, he simply played the verses three times.  Didn't play the chorus at all.  It never occurred to me that could be an option; plus, I liked that a lot, so I'm following his lead and just playing three verses.  

    Also, not surprising at all... his way of playing Meeting in the Air is much better than mine.  I tend to play a very direct melody line.  Freil had a subtler approach.  He wound in and around the melody line, in ways that would never have occurred to me, lending his variations a much more sophisticated feel.

    With some effort (okay, a lot of effort), I listened to his version of Meeting in the Air over and over, working on learning how he did it.  Unless you're very familiar with Friel's style, you probably won't hear the difference.  But for those of us who knew him, it's there.  The first and last verses are my style.  The middle verse is as close to how he played the song as I can get.  The difference blurs a bit, because over time, fiddling with the arrangement, some of  his style blended with mine.  That's fabulous, because I'd love to be able to play more like Freil.

    Regardless, I'm happy with the arrangement.  I can tell what's mine and what's Freil's, and love the fact that even after all these years, I'm still learning from him.  

    The video itself is a whole other story.  I have a new (outdated, but new to me) cell phone, and struggled with the settings.  It has problems with the audio.  It sounds like it's playing underwater, with strangely distorted sounds, and halfway through the video the audio stops entirely.  My final attempt was with the lower resolution setting turned on.  It was the best version I'd played, out of several hours of trying to fix the video.  By that point my hands ached, and I was getting tired to the point of starting to play worse, rather than better.  So I took that final effort as 'best effort' and called it done.  The playing is fair enough, but the lower resolution makes the video itself disappointing.
    I'd like to fix the audio issue, or at least figure out what's going on.  But... the video plays with perfect timing, and I never use the original audio anyway.  I always use Ableton to record while playing, export it as a Wav file, and overlay the Wav on top of the original video's audio track.  It's cleaner than the original audio, with none of the ambient noise, barking dogs, etc.  So, the odd audio isn't an issue in this particular situation.  At least, not for making these piano videos.

        I've been working on this for a couple of months (or longer).  It would have been easy enough to do a simple arrangement in the key of C.  That's always been my wheelhouse.  But for these videos, I try to change up the keys a little, and offer greater variation in each verse.  With age and covid affecting my memory, it takes longer to get comfortable with an arrangement I like, and my ability to play it perfectly is based more on good luck, no matter how much I practice.  So, please pardon any errors.  The style is there, clearly enough that other pianists can take inspiration from the style and arrangement.  Aside from the actual video of me playing the piano... there's also a "how-to" video using Midiano (see sidebar link to Midiano) to play the song at normal speed, and half speed.  

    In addition to the how-to, the Midi file for Meeting In The Air is available on this page for download.  You can download the file, go to Midiano and play it, which comes with a variety of options that will help in learning to play the song.  You don't have to use Midiano, any Midi player is fine, but I don't know of any free player that can do everything that Midiano does.  Actually, I don't know of any better midi player at all, paid or free. 

     If you read sheet music, a pdf file is also available for download.  All the downloads are available for free, on this page.  (At some point I'll consider adding appropriate affiliate ads, maybe a "buy me a coffee" link, but as of this moment, haven't looked into them yet.)    But even then, there's no obligation, no charge to download.   Get the files, enjoy them, but if you share them, please credit me for the arrangement.  :^)

VLC Media Player for Transferring VHS to MP4

 


    I mentioned OBS in a previous blog, as a great free option for capturing video.  I'll have add a caveat.  It's great, when it works.  When it as working, it was perfect.  The first time I ever used it, it felt like a godsend.  Now, I have another videotape to capture.  Booted OBS, it still captures video great, but no audio.  I hadn't changed anything about it.  Settings were still the same, hardware still the same.  I'm using AV2HDMI, by the way.  Sneered at by professional VHS restorers, but they consider a minimal set-up investment to start at $1,000, and freely recommend much more expensive equipment if you're serious.

    Those guys are exactly that - professionals who make a living salvaging old videos at the best quality humanly available.  I had to wait weeks to afford the $35 I needed for the AV2HDMI unit plus an HDMI to USB cable.  Would love to have the pro stuff.  I used to do weddings/industrial video production, so once upon a time I had most of the gear they mention but that was decades ago. Back in the first great days of video production using an Amiga 4000 and NewTek's Video Toaster.  Revolutionary days back then.

    Back to modern times...after several days of research, studying, trying to learn, following multiple guides and suggestions, it started looking like it wasn't a hardware issue, but a compatibility issue.  OBS's main strength is as streaming software.  Seems like video capture is kind of a side effect, and doesn't work equally for everybody.

    Given the number of other people online making the same complaint about OBS - no audio - and the lack of any consistently successful solutions, I had to give up.  I did try Virtualdub, but really had my doubts.  While the software will run in Windows 10, it's specs list Windows 98, ME, NT4, 2000, XP, Vista, and 7.  While that's a huge spectrum of continued support, it's age and lack of mentioning Windows 10 put me off.  Gave it a try, the quality was fair, but most disappointingly the only output format was AVI.  Some modern media players don't even recognize AVI, others struggle to play the audio in an AVI.  For the record, 5kplayer was great at playing AVI files. 

    The biggest problem with AVI was that I could only record a few minutes and then it auto-stops.  Some very minimal searching on google, and I found that AVI files were originally limited to 2GB, and using some tricks with pointers, can go to 4GB.  I'm not certain that's the problem here, but it's a limitation that MP4 doesn't have, so that disqualified VirtualDub for me.

    There were a few paid options, but I didn't look into them.  I've already invested my limit.  :^)
Then I remembered that VLC Media Player has a rather obscure video capture system.  It didn't work for my previous capture card, so I'd forgotten about it until yesterday.  Didn't even have to update, it was immediately compatible with AV2HDMI.  There were still some bumps in the road, but at least it worked with the hardware, and grabbed clean video.

    First problem?  Defaults to AVI.  The initial guides I found all lead to saving the file on the default format.  Plus, the guides were a bit outdated, so I had to blunder around blindly on the parts that weren't accurate any more.

Eventually, I found this page - How to record screen with VLC 
If you want to see the process that worked for me, it's on my next post - step by step images, and an example of the video:  VLC Media Player Transfer to VHS

The article offered instructions for multiple techniques.  The most useful part for me was the section on recording a video.  You have to read between the lines a little.  But following the steps, the article got me exactly where I needed to be. 

    The best part, when you get to "Convert/Save", and the option to create the file name, you can choose MP4 format simply by TYPING .MP4 AT THE END OF YOUR FILENAME!!  That seems too little, too simple, it feels like there should be a button to select or a preference somewhere.  VLC actually offers a lot of format options to save in, and it's very simple once you know how to get to it.

I just did a test video, running for over an hour, and the quality was great, the audio was perfect, and it recorded the entire hour-plus.  Finally, a reliable way to get video from VHS tape to my computer!!

Used Laptop for the Hammer-88: USB Problems

     Just an update based on a simple fix for a long-standing problem.  Going way back, I originally had one very good desktop to do everything.  It's 6 or 7 years old now, and still good, but no longer great.  Over the years, some things started conflicting with others.  The usual victim was system audio.  

    This caused the biggest problem with Ableton Live Lite and M-Audio's Hammer-88 keyboard.  Sometimes the audio drivers would quit working randomly.  The  most consistent and annoying villain was when Microsoft did a Windows "update/upgrade."  EVERY SINGLE TIME.  I only know a couple of swear words, but I've used them many many times at Windows updates.

(Warning - Upcoming Rant)
    The problem could sometimes be fixed easily (usually the random occurences.)  Other times (looking at YOU, Microsoft...) it could take days or weeks to get the audio to working reliably.  Sometimes it took so long, another update would come out just days later and we'd start all over again.
    Helpful Hint:  This website provides a link to a trouble-shooter that could fix most of the audio problems in moments:
https://support.microsoft.com/en-us/windows/fix-sound-or-audio-problems-in-windows-73025246-b61c-40fb-671a-2535c7cd56c8
    Yes, I'm aware it's a microsoft link.  That doesn't make me like them any better, since it was nearly always their OS updates that triggered the problem.  Just the same, this is the first thing I try when the audio stops working.  Click the link on the page and allow the app to test for problems.
    The weird thing is, it always reports "no problem found", and starts suggesting random things to try... but actually fixes the issue, at least most of the time.  So I click the "Open Get Help" button, let it do it's thing, then close the window after it reports failure.  And that's usually all it takes.
    Other times, it's as simple as checking "Sounds", going to the PlayBack Tab, and finding that the update has totally played havoc with speaker output assignments.  For some reason, it would reassign a new random output as the default.  Sometimes it would go to a legitimate speaker, like the one built-in to the monitor.  Other times it would choose options that had no output at all.  Re-setting the correct speakers as the default option will typically fix the audio, but sometimes it has to be reassigned as the default with every reboot.  Eventually it sticks, until the next system update.
    The worst ones... the mystery issues with no reliable fix... were the worst. This is part of the reason I quit playing.  It was so consistent, there were so many times I just wanted to 'play the piano' but couldn't, I gave up for a while.
(Rant Over)

A Dedicated Laptop
    In a final attempt to solve the problem, Monique found a used laptop on an Amazon lightning sale.  It's an older HP EliteBook.  Old enough it was originally sold with Windows 7 installed.  It's running Windows 10 now, but that's pushing things.  I don't install extraneous software.  Primarily Ableton, plus CCleaner and Irfanview.  And my favorite browser, Vivaldi. 
    Ableton 10 Live Lite - dedicated to the Hammer 88.
    CCleaner for it's utility toolkit and easy system cleaning. 
    Irfanview for the times I need a screenshot. 
    Vivaldi mainly because I used to use Google Drive to swap files.
    Our working space is tight, so the keyboard is on a wall-mounted shelving system, right beside the door.  It's easy to bump the keyboard while walking past it, and I thought maybe too many impacts caused the issue.


The Ultimate Fix: A USB Hub
    Eventually I realized the problem was the USB port the keyboard was attached to.  The laptop only has 3 USB ports, one to an external audio driver (the Air/Hub, by M-Audio), one to the keyboard, and one for the mouse. Not enough to go around with one having intermittent problems.  We had a 7-port powered hub.  I tried it, but for some reason when the laptop is powered down the hub still provides power to the Hammer 88 and to the mouse.  I didn't want the keyboard to be powered up non-stop all day long.  Seems like that would wear the electronics out faster.
    For about $15.00, we found a great USB hub on Amazon, by Sabrent.  It's powered, has 4 ports, and each port has a dedicated on/off switch, with a light so you know which ones are on.
    Now the keyboard and mouse are connected through the hub.  I also keep a USB memory stick on one port, for trading files between computers.  And the fourth port, just because it was available, provides power to a VCR-to-Computer converter.  Only the ports in use are powered up.  And when the laptop is turned off, I turn off the hub ports as well.  
    Now it works great.  I can play the keyboard reliably, at any time.  And turn the peripherals on/off as needed.  It's amazing when things function like you need them to!!

    With this setup it worked most of the time, but frustratingly there were still days it didn't.  Sometimes on a reboot, the laptop would not communicate with the keyboard.  Occasionally reconnecting the cable between them, but not always.  I started worrying that after all these years of not getting to use it, maybe the keyboard was aging, connections failing, who knows.
