       | I love how a programmable piano-roll was clearly forgone for a
       | great big long manual one, because it looks cooler.

       | Reminiscent of Wintergaten's Marble Machine, which continues to
       | evolve as Martin Molin works on it.
       | 
       | Full song, with an earlier version of the machine:

       | Martin is working on V3 of the machine. Plenty of updates on
       | Youtube: https://www.youtube.com/c/Wintergatan/videos

         | Is he? Last update on V3 was 5 months ago. Last update from him
         | was 3 months ago about a new studio.

           | I've been following his journey for years, it's been a
           | fascinating and some times heartbreaking story not to
           | dissimilar to Sisyphus. Every other chapter is about him
           | renewing his mental strength, grit, determination, and then
           | months later tearing it all apart because of fundamental
           | flaws. Repeat for years. His mental health is an underlying
           | theme throughout the story we're watching and I worry for
           | him.
           | 
           | With that said, he is truly an imaginative and great engineer
           | and musician and while my discipline is primarily software,
           | he's taught me a lot about design principles I apply today.
           | Namely, keep things simple, emphasis on unit testing and
           | measuring results, recognizing and addressing sunk cost
           | fallacy and many many others.
           | 
           | I've grown to really respect and admire him. But I fear this
           | project has a stranglehold over his mental health and I fear
           | for what that means for his future if he cannot get to a
           | place he is truly happy with.
           | 
           | God speed Martin, I hope you can get the boulder up the hill
           | one day.
           | 
           | edit: Update, after some sleuthing, apparently he is moving
           | and taking care of his family right now(?) https://www.reddit

         | I love its mechanical-only design; that really is a piece of
         | musical art. And at 1:30 in the video, it looks like LEGO is
         | used for the encoding pegs (also possibly some gears and
         | supports at 1:36).
         | 
         | Someone else made an entire version in LEGO [1] [2] but without
         | marbles and playbacking to/covering the original:

         | https://youtu.be/WN90HYiFpAw?t=736 His recent update is good
         | watch.
         | 
         | He learned after 3 years that he made a few things too
         | complicated because 'it looked cool' and he should have instead
         | kept the design 'dumb'.

           | His journey post v1 has been fascinating to watch. I hope he
           | eventually makes a full length documentary based on his
           | vlogs. It's a great story about the relationship between
           | ideas, execution, business, and real life in the context of
           | the modern maker economy.

         | If you look back through the channel's previous videos, other
         | versions of that conveyor belt are used as a rolling road to
         | test different types of suspension for lego cars and
         | motorbikes. Really cool stuff in there.

       | A possible mod to add dynamics: shape the rear part of the
       | "stick", the one being hit by the programmable pins, so that by
       | inserting or extracting the pins from the rolling cylinder, the
       | sticks can be raised to different extent emulating the hitting of
       | a drum with different force when they're released. Dynamics makes
       | a huge difference in making electronic drums sound more natural.

         | Although it doesn't seem made using LEGO Mindstorms, I'm sure
         | that is the one you mention; it was quite successful at the
         | time among robot building aficionados.

       | 
       | It was funny after electronic drums started to gain steam that
       | software sequencers started adding a "humanization" attribute to
       | take the robotic perfection out of drum sequences. Sort of the
       | opposite of auto-tune.

         | I used a Roland R8 in the late 80s and loved/hated it for the
         | humanization functions they added to the instrument; it could
         | subtly modify the sound parameters at each hit to make it sound
         | like it came from a real person hitting a drum or cymbal in
         | different areas, however it lacked the most important one:
         | timing. A human drummer will never be accurate to the
         | millisecond, but rather will apply very small
         | anticipations/delays at each note, with good drummers capable
         | of doing it on purpose within given limits. Adding such a
         | feature would make it sound even more real. Nothing compared to
         | a real drumset played by a real drummer, however: the number of
         | variables is just too high to be accurately emulated by today's
         | technology. AI might help with that, but don't forget about
         | latency: when drumming live, a few milliseconds is already too
         | much delay.
