I'm looking for really off the wall, cool, or complex nonsense.

I put together a racing reel set (1st August / Vincent Broderick's / Séan sa Cheo) which is a lot of fun, but I'm looking for new stuff as well.

Other cool tunes I haven't found a home for:

* Beare Island reel

* Silver Vale jig

* With Ourselves

* The Independence (hornpipe with the B part essentially turning into a jig)

I'd love to hear what you're playing (or aspire to play)!

I am attempting to vibe code a more advanced multi variable physics model for an Irish whistle/recorder, including the mouthpiece physics and overblown second octave behavior.

By my understanding, the flute calculators (Flutomat, WWIDesigner, etc) do a fairly spectacular job based entirely on modeling the resonator, since player embouchure adjustments essential compensate for the differences in the second octave. However, research and personal testing show that the same tactic doesn't work for fipple flutes due to the fixed "embouchure"forbidding things like increasing lip cover or attack angle.

I've got most of the parameters accounted for so far and the solution is getting closer to matching experimental data...but I'm facing a rather large issue with the playing pressure profile.Theory says pressure increases 4x per octave in one source and 2.6x in another. My own attempts at data collection have suggested a third, non-linear profile altogether and none of the three options close mathmeatically on other experimental data.

Has anyone run experiments with an "artificial mouth" or have any advice on its creation? Any other advice on data collection methods would be incredibly helpful.

Thank y'all in advance!

(Please forgive my singing...)

Does anyone recognize this old traditional song?

I am several months into trying to find any mention of it online and I've officially finished searching through all of my friends CDs and cassettes.

This is the first verse to the best of my memory:

https://pastewaves.com/player/15912f41-4128-497d-ba1b-5c1ece5aa00e

>"Oh Come to the sea side and hear the wild waves.
On the dark rocks we'll stand as the storm wildly raves.
And we'll watch the white seagulls o'er tempest and spray.
For the mighty ocean ridge is fierce and loud.
Oh come come away."

The second and third verses start with:

>" Oh come to the hedge row.....
(Something about the blackthorn and bramble)..."

And

>"Oh come to the meadow, with gay flowers all around...."

Exhaustive Google searches and AI only managed to find the first verse by lyrics and it turns out that it was a poem from an older book that someone wrote a few more verses for and turned into a song.

I remember hearing it first some time around 2006 in either CD or cassette format, but it may have been recorded way earlier. The whole album was English language acapella singing "field recordings" in the Sean-nós style. I had thought that the singer was either Paddy Berry or Paddy Tunney, but I couldn't find it in the CDs that I could track down.

Any help or leads at all would be greatly appreciated. This has been driving me crazy.

Printer: Bambu X1C - 40C chamber temp (fixed), 0.2mm nozzle (clean, newish), 90 C Bed temp (works perfectly with brim)

Filament: Bambu Lab Black ABS (dried, but at 60C, rather than the recommended 80C), 100% infill, 2-3 walls (out-in-out and in-out print order)

Model: Cylindrical Irish whistle mouthpiece - (appx.) 20mm diameter x 100mm height with a solid sloped mouthpiece leading to a 13.5mm internal cavity (~3.5mm walls). Print time is ~14hrs.

Orca Slicer parameters: all accelerations except travel locked to 500mm/s^2. Outer walls - 30mm/s, inner walls - 50mm/s, infill - 75mm/s, Arachne walls, Brim, No skirt seams (ignoring Z seam quality for now out of necessity), no retraction reductions, precise Z height and walls, 0.02 PA.

------------

I have have had no issues getting fairly consistent clean prints with BL ABS at 0.1 mm layers, but lower than that ends up looking like a mess. After an embarrassing number of trials tweeking Orca Slicer setting essentially at random, I was able to get close to same 0.1 mm layer height quality with 0.06 mm layers, but the surface finish is a bit "crunchy" and VFAs are still way beyond acceptable.

However, the 0.04 mm layers are an absolute mess. Deep diagonal "finger print" surface defects going up the Z axis on the leading edge of the seam, VFAs that look like I've got some kind of glitched fuzzy skin texture (I don't, the model is extremely high resolution and the VFAs don't match model edges), and lots of crunchy blobs on the surface And internal geometry.

Recent Trials:

1. I ran this all by AI and tried the suggested lower temperature of 248 C and ran flow ratio tests, with a few other changes to retraction which improved quality at the other layer heights. Besides the highest trial (1.03 ratio) looking best, it is still a far cry from usable. For comparison, I have been printing 0.1mm layers at a 0.96 flow ratio.
2. Taking flow of 1.02 and increasing temp to 252 C, I trialed part cooling fan speeds of {0, 20, 40, 60}% and results paradoxically seem to support higher fans working better. AI suggested that rapid cooling was the leading cause of the fingerprint issue.
3. Next I plan on pushing the cooling fans a bit harder to see if I can get smoother flow without compromising adhesion, then rerunning PA calibration. The only other thing I can think to try is increasing print speeds so that the filament spends less time in direct contact with the hottest part of the nozzle.

If anyone has any suggestions, I would greatly appreciate the help.
