- an opl2 song cant you believe it
first original in 3/4 as well i think
only sines and absolute sines were used, only am (alg1 on 2op opl) was used
Made with Furnace unstable build by tildearrow.

my discord server link has moved to the about me section :)
finally, the world's first opl2 tune
none have existed before this one
But FLDE made one before this?
the opl3 finally catches a break after the torture it endured from abstract
that break was short lived 😔
So much for that
But this is OPL2
We're not actually talking about this video, to be more clear
Also, this song feels like it would fit a rainy night in a car going back home.
algorithm recommended me this, and this must be how it sounds to listen to algorithms
welcome to the club, where abstract makes furnace produce sounds you sometimes could mistake for being straight out of a professional DAW
thank you abstract 64 this music will be perfect when im on the winter car rides to my grandparents house

this song is so beautifully calming every time I listen, it's nice to have a couple less intense tracks in these mix playlists

this music actually strangles my hold
randomly showed up on my feed I don't regret clicking
stranglecore confirmed
mid-90s demoscene inspired by JRPGs vibe.
You are genuinely one of the best musicians I've found on this platform and I love every time you upload something.
Awesome. It is a very nice piece of music, and even though you limited yourself to sine and absolute sine, there is a lot of contrast in the timbres imo. I really keep listening to it for pure enjoyment.
I bought a Reface DX some years ago to train myself with FM synthesis. I only knew that this was the technology behind the Megadrive system. Then I discovered that Yamaha made a lot of FM chips over the years, including the so-called OPLs. I was very surprised to see that the older OPLs had features that the Reface DX didn't have, as choosing between several waveforms for the (two) operators. Whereas the Reface DX operators all have two types of feedback, saw-ish and square-ish.
Then forgetting about technical details, a pure t -> abs(sin(t)) really sounds close to a PWM to me. Which can be approached quite nicely by Reface DX's paradigm : A column of three operators 1 modulated by 2 modulated by 1, or a column of two operators [1 with square feedback] modulated by 1. By tweeking the latter choice, I feel like I can get close to the sounds in your composition.
All of this is very mysterious to me. If I only listen with my ears and turn of my brains, I feel like the 4 waveforms of the OPL sound like this :
Sine = Sine (congrats to me)
Half-sine ~ Sawtooth with a good bunch of cutoff
Absolute sine ~ PWM
Pseudo-Sawtooth ~ Sawtooth (congrats to me)
It feels logic to me that if you have the computational power to approximate the composition of sine waves, then you also have the computational power to approximate the composition of these 4 types of functions. I'm surprised not to see the Square wave nor PWM in the OPL2 panel (square is available in OPL3 if I'm not mistaken), as I don't see the computational challenge in composing with a square or PWM function (which boils down to an "if" statement imo, but I'm not hardware programmer maybe there's a problem).
All this leads me to think that the choice Yamaha made with FM-X and Reface DX, namely this system of saw-ish and square-ish feedback on each operator, is a good one, a very versatile one. To get close to OPL2, you can do the following imo:
Half-sine : moderate amount of saw-ish feedback on the carrier
Pseudo-sawtooth : great amount of saw-ish feedback on the carrier
Absolute sine : impossible for less than two operators IMO : either moderate amount of square-ish feedback on the carrier and moderate amount of 1/1 modulation (my favorite), or 1/2/1 tower with moderate amounts of modulations
And with their modern system, you can vary continuously (just kidding) between all these possibilities.
Sorry for this long comment, but until I listened to your track and tried to replicate your sound, I was dubitative about Yamaha's modern FM paradigm, and felt like it was inferior to their older systems as OPL2, OPL3. Now I feel like it is an excellent paradigm, and that Yamaha's people are right about how to handle FM synthesis efficiently. I don't regret anymore choosing the Reface DX over the Opsix (which also makes awesome sounds).
PS : I have a technical question for you. To me, it is way more easy to listen to SNES music for extended periods of time with headset than to listen to Megadrive music with a headset. To me, this may be because the sample system with (inevitably) high compression of SNES leaves you with very few high harmonics, whereas Megadrive FM synthesis leaves you with lots of high harmonics. Do you EQ or compress your parts/tracks before uploading them or is this pure OPL2 output? If not, have you tried it ? Do you feel the same as me about listening to SNES/Megadrive ?
thanks for the comment!! was a fun read through
answering your questions it is a raw furnace export of opl2 emulation without any post-processing :)
i do also agree that with the interpolation on the snes audio it is more listenable on the long run than md stuff since its really harsh on your ears sometimes
Kinda looks like one of the waves of the first oscilloscope square thing
This tune has a quality I struggle to put to words... like an old lament rendered in laminar flowing FM tones.
It sorta fells like something that'd play when you're in the ancient temple where you find that ancient evil sealed there just want to hang out and play video games with you...
So damn good! Great work!
the music in my dreams:
IKR? Dreams can have some of the most insane music you'll ever hear, and then you wake up and forget it completely 🙃
Ascended immediately when the song started
if music were magical, this would be a sweet dream spell
great...
it is so beautiful
i want to listen more A64's 3/4 time songs
Found this by esotheric and unexplainable means, worth it.
this is unreal, so beautiful
Love it! Makes me think of the ocean.
bro at the start I hear the nico nextbots motif 💀
Nice OPL2 tune!
babe wake up abstract uploaded a banger
stickerbush symphony vibes
This song is so angleic 📐
Nothing to see here, just abstract 64 cemeting themselves as my favorite chiptune artist yet again
Man I'm so used to i-viio-bVII-IV progression hearing you using i-viio-bIII-IV instead at 1:23 makes it sound so off 😖
Maybe I should fix that myself 🤔
So pretty 🤩
Nice OPL2 tune!😄🤩😎👌
abstract has chill /ref
What a banger of a bassline!
Btw the result is 35
nice title, love the concept
Incredible!
nice and smooth
very mathematical
it's peak...
Cool song!
Absolutely wonderful! 😀
That's nice!
Very nice!
Idk what an opl2 is but this sounds beautiful
thank you :)
were you possessed by Jeroen Tel
liekly
operation-wave (lol)
We love chill OPL2 tunes
Cute music
Beautiful actually
#believe
😁✌️
Bro isn't that equation just a line? How does that even play?!
is this cursed cathedral x un owen for that intro
cursed cathedralpilled for sure, i did NOT expect un owen to make a cameo here tho LOL
stranglehold 3?n‹!?!?!?][[
of course it's abstract64...
64*cosh(2*(t))^2
What's opl2, opl, 2op, and alg?
songs to steal to...
HOW DO YOU DO IT MAN
2-op additive operator mode sorcery type of stuff
Stranglehold?
Cybergrind >:v
are you single bc i showed this to some girl in my class and she began blush. just incase, lock your doors tomorrow
