C64 Jeroen Tel's Stormlord music oscilloscope view

- Found a player that solos the voices correctly (java SIDplay2), so all synchronization and ring modulation effects are visible. I also wrote a program to draw the wave forms instead of filming my oscilloscope! :)
On this one I had to patch the code in the SID file to get all 4 tracks, including the 4 bit sample playback. - บันเทิง

I really love how the 3 main SID channels look around 0:50 and 3:30
I can hear them in my head anytime but to see it visually is simply fantastic, especially after this many years...
+Jeroen Tel Oh, so is the volume tick channel doing delta?
Did you record these samples with that fancy C64 add-on thing you showed off in an interview?
Definitely most of them (especially the voices).
Great use of this 3 channels. I prefer Cybernoid ii song indeed
But the best part is how you got trixy with SID and got those 4 bit samples! BTW how much space in the memory did those take?
I love it when C64 music uses samples. This and Turbo Outrun are two of my favorite C64 soundtracks. Jeroen Tel is a genius!
Thank you! (Humbles me).
+Jeroen Tel You're welcome, Jeroen.
For me your use of samples in Hot Rod's intro (obscure, but really great conversion) wins! Can't deny how awesome the C64 Turbo Outrun was though...
Thanks, Greg! :-)
I was quite pleased with the end-result of Hot Rod. :-)
I friggin love the moments when the SID main channels are playing the same notes! It sounds so harmonic!
Dearest, dearest snipe and wib, thank you so much
0:30 this bit with the layered triangle waves is so cool.
thanks for uploading these I was born over a decade after the c64 but man do i appreciate the music they made on that thing
+Bunsen : Awesome, man! =)
I was born 2 decades after the c64 was made and I have to say it has some GOOD music
I love how it starts with a clock striking 12.
ST-ST-STORMLORD
CANT STOP WATCHING
This guy can make the old C64 sing, well done!.Great tune!.
dat AC coupling at 0:00
What?
I think he means in the begining of the sound the DC bias is removed from the AC signal, thus the big downwards slope in the begining.
That loud electric clunk sound at the beginning. You usually hear it when plugging in headphones or turning on speakers with an on-off switch.
The bridge is a killer anthem!
Nice sample of the D50 preset "Digital Native Dance".
That's right +6581punk! =)
This song is somewhat catchy!
Wow, hello
Thank you. I never knew how good the C64 version of the song is. I can see why people prefer it over the Amiga sound track. In the day I only knew about the PC version, which had no music at all! I'm just finding all about Stormlord properly now.
+Clint Hobson : Thank you! =)
This is by far one of the greatest tracks ever composed for the Commodore 64. This is up there with Cybernoid 2, Arkanoid, Comic Bakery, and the soundtrack to Last Ninja 2.
Don't forget Tetris... The 25 minutes version... Pure Genius... ❤
Intromusik von J.Tel! Einmal mehr wurde ich verzaubert damals - und bin es immer noch...
And i thought Rob Hubbard was the SID god..(well,he still is,but he has to share this title.)
A Noose dont forget about Tim Follin.
So nice of you to say that... Rob still is the Godfather of SID, though. Maybe I am the god-nephew of SID then. :P
And Martin Galway...
Both members of the Higher SID Counsel , that's for the sure.
Roger Wennström: Absolutely!
6:08 when you feel something come out your spagetti noodle
I played this on my XRocker, bro I felt my legs and arms vibrating from the vibrato
Magnificent tune
Long life Sid!
Nice use of music!
God bless!
I hear this for the first time and I love it!
Those drum samples remind me of the Yamaha PSR-82 drum kit!
So friggen good!
don't forget the sample: warmlard!
funny how this made its way into _Introducing Google Tulip_ at 0:38 (the volume "channel" is duplicated to replace the first channel at the top). The duplicate pcm channel looks a bit weird though...
holy shit
youre right
that is fucking amazing
dat some gr8 chiptoone
This is very different from the Stormlord music I remember on the Amstrad CPC :O
fucking sick tune
Don't know why but this song reminds me tears for fears's mad world
I'd love to see other Jeroen Tel tracks put through this such as his versions of Wilderness from Golden Axe, Magical Sound Shower from Turbo OutRun, After Burner from After Burner and his OutRun Europa theme.
Likewise! :-) I love seeing my SID tunes like this! :-)
Jeroen, I've loved chip music for a long time but it was your version of Wilderness that got me really liking the SID chip. Thanks, man! :D
So nice to hear that, Jamie! It means a lot to me. :-)
@@JeroenTelMr. Tel, you are one of my heroes, and a master musician! Maybe you could join one of the still existing C64 demogroups (very good demos were released at the X party this year!), and continue and ENHANCE the EPICNESS of the little "old" computer that we all love so much? Heartly greetings from Germany ❤❤❤❤❤❤❤❤❤❤❤
The sample voice is the ultimate hack! Who came up with it? Imagine the patience it took to arrange one click after another to make music...
I think officially it was Martin Galway who did the first sample based track ON TOP op the 3 main SID channels with the music for Arkanoid. (Super simple, but it stood out)
@@JeroenTel That was an excellent track from MG.
I know he's saying Storm Lord but to me it sounds like Farm Lock, which doesn't even mean anything
Haha! Well, that's 4-bit sample mumbling for ya! XD Funny!
I hear "bum rush"
I hear farquaad
i for a second thought it was saying "palm lord", that was so close xd
This is a very Halloween 1988 mood
How does this song have 4 voices even though the 6581 SID chip has 3 voices.
It's actually not 4 voices. The SID chip has 3 channels (voices), but on top of that it has a volume register that can be set to 16 difference volumes (and this is what can be used to play samples with. Only 4 bit (compared to for example CD, which has 16 bits per sample). They key to this (keeping the 3 SID channels audible) is to keep the middle volume exactly in the middle.
$F = max volume, $0 is min volume $8 = DC (standard) volume.
So the illusion becomes that there is a 4th channel.
Thanks!
I still don't get the thing about the 4th voice on a 3-voice SID chip...
iirc whenever you adjust the volume register in your program it makes a small click noise at a specific frequency and that click can be repeated several times in the span of a second allowing you to change the pitch of the click. Doing this a shit load of times leads to what you hear.
I wonder how you managed to record the other voices without the 4th one mixing in... I couldn't figure that out when playing around in JSIDplay2.
+Collision Detection
You have to patch the SID file to silence the sample track.
Dig around, look for writes to the volume/filter enable register $D418.
If code look like this :
LDA#$08 (or another number)
STA$D418
it is initialization of the register, leave this alone.
The other one(s) need changing. If the music does not use filters, try NOP'ing them out. ($EA,$EA,$EA)
If the code looks like:
ORA$XX(XX)
STA$D418
you can change the first line to LDA#$08. Add a NOP if 3-byte ORA is used.
If it looks like:
ORA#$x0
STA$D418
self-modifying code is probably used for speed, look for and disable writes to the #$x0 part of the code and then change the first line to LDA#$08.
You may have to do the full patching.
Change the writes to $D418 to a JSR to a vacant place in memory, write this code there:
AND#$F0
ORA#$08
STA$D418
RET
If CPU time is strict, you may have to change JSR and RET to absolute jumps, JMP, shaving off 6 CPU cycles.
If CPU time is even stricter, it may corrupt the song.
Note:
There is more ways to skin this cat. And this is straight from the top of my head, and may contain errors :)
see jeroen the original composer is using your osciliscope vids forhis kickstarter how cool is that you going to do an more of these vids m8
Almost sounds like Amiga music.
2:10 😌
Very Queeni.
Does altering the filter that little bit change the tone much, if any, at all?
How come there are 4 channels?
If you already know about the C64 SID chip, they you may have known that it has 3 channels. The 4th channel used here isn't even implemented by the designers of the SID chip. It's just a flaw in the 6581 model of the SID where the 4-bit master volume register affected the DC bias of the audio output, even if the 3 main channels are silent. This was fixed on the 8580 model.
If the programmer updated the 4-bit volume register quickly enough, they created a 4th channel which could play raw PCM. This is extremely CPU-intensive on the C64 (as well as many other 8-bit systems), so it was meant to be used in non-gameplay parts, such as the loader and/or the title screen.
I Want Download This Music
wow.thats really scary...
is there any way to extract the sample track alone ? I want them sooo bad
Well im only really good with the actual c64 hardware, on modern pc's im a real noob....but thank's anyway...ill give it a shot
The main bass sound on the intro is DigitalNativeDance from a Roland D50.
Hey wait, it has 4 channels,the c64 has 3 channels,so is this not cheating?
I'd assume the way they played samples is by timing these clicks just right to make certain sounds, just as programmers did with 'beeper speakers' on computers like the Apple II and the IBM Computer (I'm not too sure if that's what IBM's earliest computer was called, so I'm just calling it that for now.), and, I'm not sure, but I'm guessing that the volume the tune is changed to would be the volume of these clicks, too.
Wasn't the office for MOS near Philly?
Ancient Apparition Yes, in Norristown.
We used the main volume register to make samples (actually all 3 channels are affected during the process... ;-)

This might just be the dankest song of all time
Where does the 4th, bottom track come from?
that's a quirk from the sid. the 4-bit volume dial from each voice can be manipulated to play pcm samples, in 4-bit depth. that's 'cos that volume dial produces clicking sounds when the volume changes, if i remember correctly. on the 8580, the second and last revision of the sid, commodore pretty much removed that noise, making samples very, very quiet. so that's where digiboost comes, it's a hack for making this 4-bit pcm sample playback louder on the 8580, nearly the same level as the original 6581.
C64 4 voices?
Yes, you were able to use the master volume control register of the SID to achieve a crude sample playback. That's the fourth channel you see.
ultimate hack :D
Nah, the ultimate is a SID tune called Fanta in Space. 4 channels of 8-bit samples, 2 channels of SID oscillators and filtering of both.

This should be a Geometry Dash Level

if i would have made a show about clockman (of the description of the first guy who posted about him) i would use
0:00 - 1:47 as the theme
0:46 and 3:12 are schmackin
Awesome stuff. May I suggest another CLASSIC: csdb.dk/sid/?id=28199 Robocop 3 by the master Jeroen Tel.
Thats a good one! Coming up next! :)
ATTN @Rolf R Bakke: This seems Not to be Stormlord C64 tune - please check what game this is and search other vids with stormlord gameplay, and rename this..best!
This is from the Stormlord loader.
@@RolfRBakke thx Rolf for the clarification - in-game music was the real deal, a real kicker - could you please rename this vid to reflect that to .."loader", Best!
likes:dislikes is 696:9. nice.
Would love to see this with more contemporary SID music... like this one here: csdb.dk/release/?id=133926
Coming up :)
A good song speaks to you. This one had all the elements which I consider making up a good song. Most c64 music is trash but I will give this one a like.
If you think most C64 music is trash you haven't listened to enough. Check out some of Rolfs other oscilloscope videos. He has great taste. Check our Jeroens Robocop 3
Or Turbo Outrun
What about "Hot Rod - Introduction"?
When and where did you hear "most C64 music"?
@@inphanta He must've skipped Rob Hubbard day :D
This music reminds me of Michael Jackson.
And that, +EXISTENCETM is a great compliment, to me at least. ¦-)
Too bad the game sucked.
