  1. Thanks! Thanks! For what it's worth, it looks like "86 Swiss & German Folksongs for Anglo Concertina" and "75 More Irish Session Tunes for Anglo Concertina" still aren't available in Kindle format.
  2. Spotted this good-sounding playback of an old Edison cylinder of an Alexander Prince medley called Forgotten Melodies.
  3. Just saw this auction: https://www.the-saleroom.com/en-gb/auction-catalogues/gildings-auctioneers/catalogue-id-srgil10336/lot-2dfd0fc2-40d9-4904-a598-afb900e25baf?queryId=db378407cbeaecd3dc51843d32328b3d Does anyone know anything about a "TW Upcott" branded round (!) 20b Anglo?
  4. Sorry, I didn’t mean to imply that the book specifically addresses notation systems. I came to it with essentially zero musical knowledge (but a lot of math background), and it helped me understand things like why keys even exist, which then helped justify to me why you’d want a notation system that was key-oriented.
  5. Volume 1. Volume 2 is really only if you want to learn DSP algorithms.
  6. I will just add that, as a mathematically-minded person, the book "Musimathics" by Gareth Loy did a great job of explaining why a lot of things that seem arbitrary in music are the way they are (or at least fesses up on which ones really are historical accidents). I credit that feeling of arbitrariness with being the leading cause of my consistently showing zero interest in music classes as a child.
  7. I just added title extraction to the output, when present. I do dream of being able to automatically generate fingerings for complex harmonic arrangements. The model is actually able to do so, but the input is the hard part. Taking input from ABC means recreating a lot of the timing logic from abc2midi, which would be a pain. Taking input from MIDI means losing the looping structure of the score, and being stuck with whatever chord rendering abc2midi picked.
  8. Chords shouldn’t automatically kill it, but ones generated by abc2midi often contain chords too deep for the Anglo’s range. If you send me the file I can see what’s wrong with it. I can look into adding a title, but I don’t think MIDI files are guaranteed to contain one?
  9. Maybe some day, but ABC is easy for humans and hard for computers. In the mean time, you can convert your ABC to MIDI and then upload it. Let me know if you hit any problems.
  10. Gary's Christmas song book has done more than just about anything else to help me memorize the chord shapes for Cmaj, Fmaj, Gmaj on my C/G Anglo. 🤣
  11. I finally got my model running in a web-friendly location here. You can currently upload a MIDI file and get back human-readable text specifying the fingering. I could fairly easily change the output to something like JSON or whatever format would be most conducive to integration. And the button numbering scheme is ultimately arbitrary, just currently chosen for my own convenience.
  12. I just got this hooked up in a form that others can try. If you navigate to this page, you can upload a MIDI file and have my model generate a fingering for a 30b Wheatstone C/G Anglo. It currently prints a text output that lines up with Gary Coover's tablature system. While the model supports simultaneous notes, but you probably won't want to use a MIDI file with guitar chords rendered into it by abc2midi. The model will try to translate the notes exactly as abc2midi rendered them, which is unlikely to result in anything you'd actually want to play on a concertina.
  13. Would be interesting if we could get it working together with my automatic fingering generation project. I just implemented a version that can generate fingering from a MIDI sequence, and was looking into how to expose it as an HTTP API...
  14. I think I just had success on fixing it. It does appear to have been an alignment issue, but I didn't have to bend the lever! Since it's a hook-type action, the levers can actually slide forward and backward under the levels. It appears that this one had slid slightly too far in one direction, misaligning the button. I slide it a millimeter or so back the other direction, and it immediately felt MUCH better!
  15. I have a metal ended Marcus C/G anglo (hook-style action), and the left hand right-most C row button has been gradually becoming sticky over time, i.e. it does not immediately pop back when I release the button. It started out pretty minor, but has gradually worsened over time, and is now reaching the point where it interferes with playing quickly. I've taken the end off to examine it, and the button appears to function just fine with the end removed. I can see some wear & darkening on the button hole's felt, on the side towards the hand rest. My leading theory is that the button is rubbing against the side of of the hole, which creates enough friction to slow the release. Is replacing the felt on that hole the right next step? Or is there something I should be looking into with respect to the button alignment itself? Anything else I should consider?
  16. I always visualize them horizontally, even though I know it doesn’t make sense physically. The fact that I am a solid touch typist may influence this. Visualizing then as three horizontal rows makes it very analogous to touch typing.
  17. Will there be a Kindle version? 😉
  18. Harvey Tools makes a 0.001" end mill, which would get you close, though good luck getting a smooth finish on that.
  19. I ran across this performance arranged by John Kirkpatrick of the Evercreech Hornpipe. I see at least one concertina in the band! Sheet music of John's arrangement seems to be available here: https://www.efdss.org/55-resources/learning-resources/2527-efdss-resource-bank-the-evercreech-hornpipe I think the bounciness of the tune will work well on an Anglo, though I'm still deciding whether to transpose it to an easier key.
  20. I'm purely speculating as I have no experience making reeds. I suspect that there's something about the material properties that impacts this. The reed is meant to flex, and the shoe is not. Presumably the difference in materials between the shoe and the reed contributes to ensuring that this is the case, as would things like intentional grain misalignment between the two materials. A unitary reed and shoe would lose those benefits. I also suspect that, for a mass-produced item like an accordion reed, the machining required to make a unitary reed wouldn't be able to deliver as smooth a reed tip as electro-abrasion does, which would impact the sound. Which is not to say that it's impossible, but I suspect there's a lot to be figured out before it's clear if it's possible to make a good unitary reed.
  21. I got MIDI input working. It seems to work well, and makes it much easier to ingest longer tunes into the tool. It does *technically* work for chordal arrangements, but the way abcmidi renders chords in MIDI isn't especially similar to the way you would typically play them on an Anglo, so it's not as helpful as you might think. Here's an example of generating a fingering for the entirety of Cielito Lindo, via abcmidi with guitar chords disabled. I did successfully create a version using guitar chords, but it required a lot of `%%MIDI` commands in the ABC to get various chords in the right octaves, and it still didn't match the way you'd actually play them on an Anglo enough to be useful.

  22. I had one other idea that I think would be interesting the other day. I could relatively easily modify the model to operate on relative rather than absolute pitches, which would allow it to find and transpose to the most playable key for a tune.
