Neutrino Cloud

By Disposable Planet on January 31, 2026 4:22 pm

Another week, another LSDJ tune!   I've decided my next LSDJ album will be a concept album themed after many of the different kinds of elementary particles so all the LSDJ stuff of the last few weeks plus the foreseeable future will go on it.

Each track on the album will try to capture the vibe of a specific particle.  Elementary particles in the standard model are divided into two main categories: Bosons and Fermions.   Think of it like this:  bosons are the particles that govern or mediate energy or forces (like the four fundamental forces of the universe) and fermions are the particles that make up matter.   In previous weeks had Photon Jive which was about the photon, which is a boson that mediates the electromagnetic force and makes up what we call light, heat, radio waves, X-rays, microwaves, gamma rays, etc... and Graviton Beam which is about the graviton, which is a hypothetical undiscovered boson that supposedly mediates the force of gravity.   This week we're tackling fermions and the track is about the neutrino, which is the most abundant massive particle in the universe and which passes unhindered through most matter.  Hence the "neutrino cloud" is actually my way of saying the universe at large.  Quadrillions of neutrinos from the sun are passing through your body right now and you would never know!

This week I'm playing around with something known as the Royal Road Progression, which is a popular progression in japanese pop music.  In this song it goes under the main melody with a progression of Cmaj7 - D7 - Bmin7 - E minor - the chords being reinforced by the arps due to polyphony limitations.   The progression is IVmaj7 - V7 - iii7 - VI so be sure and mess around with it too.  In fact we don't get to the root chord until the B part or chorus.  Started out with a WAV channel synth up in a higher register as a nice change of pace and some fun mid level stereo panned arps that continue for a good deal of the song.  After the intro, the lead melodies use a simple pulse wave patch that uses W commands in a table to change duty cycles each time the notes are triggered, creating a nice variation to all of the phrases as well as giving each note a distinct quality which lets it cut through the mix.  In the middle section I again use two pseudo delayed chains to create a delay effect on the major and minor seventh arp runs.   I use some noise channel swells to emphasize transitions and of course I have some parts where the drums drop away.

Overall, I'm very happy with how this one came out.   I'm proud of the melody work, having used a lot of grace notes, L commands for bends, and vibrato swells in the phrasing for those chippy leads.

In other news, I recently finished editing and doing the motion graphics for a short promo video for Wood Chip Fest 2026.   Wood Chip Fest is an amazing and chill chiptune festival that takes place every year in Kastrup Forest in Ringsted, Denmark.   I've played there the past two years and am invited back to play again in June of this year.   Please check out the video below and get hyped up for chiptune!

As always, thanks for listening!

Absolutely loved the evolving composition on this one (and what a cool video as well!!!) - solid work 11/10 smile

awesome as always - this feels like a good thing to listen to if I were flying around a neutrino cloud

  • That intro has the smoothest PWM I've ever heard from LSDJ―is that aided by the analogue pocket core you're using, or is it really possible to somehow get that buttery of a PWM from dialing in the right wave channel frames?

  • There's so much expression and articulation in the melody (which is crazy when I think about LSDJ having just one FX per track (and only 0x20 tables))

  • Special shoutout to the gauzy bed of arps wafting about in the background (demoscene4eva heart)

Ok so it's not a pulse wave that is being shortened and lengthened.  It's a sine wave with a little bit of tweaking.   The trick is to slow down the speed of the synth and use PINGPONG mode.   But it probably sounds so smooth because it's not exactly a square wave.   I'm not actually using the W command to dial anything in specifically.  it's all automation.

Glad you enjoyed the lead instrument!    The trick is to swell the vibrato over time and also I use a lot of V and L commands together with K commands to end notes just 3 ticks shy of the next note on occasion.   That gives it a little bite in the phrasing.  This coupled with a table that is oscillating W commands so that each note retrigger is a different duty cycle.   I have the table set to go 50%, 25%, 12.5% then it hops back to 50%.   The fact that its 4/4 with most note runs being an even amount of notes together with the fact that its cycling duty cycles three times before resetting means the lead instrument naturally sounds different every time it plays the same melody or phrase even if I changed a few notes.   Sometimes a P command at the tail end of a long lead note dropping the pitch slightly adds some character as well.

Yeah the arps are my favorite section.

Thanks for listening everyone!

phenomenal track and intricate work. loved every second

Dude, I cannot get over how pretty the melodies you hit in this are, damn... Fantastic!

Oh my! The composition, the lead melody, the arps... My goodness, the ARPS! Incredible work

Thanks.  Some arpy goodness on this track!

I'm always blown away by your attention to detail. You never take shortcuts and it shows—everything you do is so dynamic and alive and evolving. Great job!

oof those arps are hypnotic and soothing while the beat and lead dance around each other.  extra enjoyed the 2min arps and how they return back to the previous section.  awesome melodies, slick drums and a head nodder. fav'ed!

Grace notes and bends galore, make this such an evocative expression with sophisticated ornamentation. Excellent! heart

Super glue

That's funny you should mention it because I always feel like I should spend more time on tracks.  I work very fast I probably only spent about 3 to 4 hours over the course of the week on this and I feel like its done aside from a coat of polish I may apply before I commit it to master for my next album.  I always want to push myself but honestly I feel like I've gotten a little lazy in my old age.  I used to spend way more time on tracks.   Maybe I'm being over-critical.   Thanks for the kind words and thank you for listening!

Thanks so much for listening!

This makes me wish I was listening to this at a chiptune festival somewhere

Beautiful chiptune! There is a a lot of energy pulsating from the drums and the bass, backing the melodies very well. I love the arps after 2:12.

This is amazing and I love the particle thematic of the album. Awesome idea.
You make some of the best chiptune I've ever heard. It's phenomenal.

I'm impressed with how much expression you're able to squeeze out of the lead in this track. Really does sound like it's singing.

so funny - i found this first on youtube and that made me realise you are here.
really love the song!

Hot dog I was jamming to some great chiptune at then I'm like "Wait I know this melodic style..." and I was right. I am constantly floored by how much style and substance you can cram into a song, and the fact that you do it in LSDJ is so much cooler.

Wonderful, that lead is so free and flowing.

This was an awesome journey, while reading the back story. Banger production!

Excellent work! Love those layered arps starting a little after the two minute mark. So cool.

Awesome as usual!
And who doesn't love some particle physics education with their weekly Disposable Planet fix!?

Love how expressive your melodic work is. Feels like a journey!

Love me some tasty chips.

Fresh! Lovely expressive lead, super wide classic arps, looooow bass and all around perfect chip mastery.

Thanks everyone for your wonderful comments - they mean the world to me!   Also thanks for listening!   Expect more elementary particle themed LSDJ shenanigans in the weeks to come!

The arps at 2:08 send me to a higher place.
I cannot fathom the work you put in there.
This track only having 4 tracks to work with and being this rich is a deadly sin!
Amazing job.

great composition and sound. momentum!
