The synth graveyard was a quiet place, tucked behind a repair shop on a rain-slicked Tokyo side street. Jun found peace there. He was a sound designer by trade, a man who believed every broken circuit held a ghost of a melody. That’s where he saw it: a Korg SF2.
It wasn't a classic. The Triton and M1 got all the love. The SF2 was the awkward middle child of the late 90s—a ROMpler with a stiff, synth-action keyboard and a gray, battleship-like chassis that felt more like a tool than an instrument. Jun picked it up. A single key was stuck. The volume slider was missing. But the power light flickered on.
He paid 2,000 yen.
Back in his cramped apartment, Jun pried it open. Dust bunnies the size of mice scattered. He cleaned the contacts, re-soldered a loose capacitor, and 3D-printed a new slider cap. He plugged in his headphones.
The factory presets were terrible. Thin pianos, anemic strings, a “Rock Drum” kit that sounded like cardboard boxes falling downstairs. Jun was about to turn it off when he noticed a tiny, scratched label near the data wheel: SF2 Custom Bank #17 – K. Yamaoka.
His breath caught. Kenji Yamaoka. A ghost. A cult sound designer from the early 2000s who vanished after a single, legendary album—an album made entirely from malfunctioning gear. Jun had worshipped that record in college. korg sf2
With trembling fingers, he held down the ENTER and COMPARE buttons and powered on. The screen glitched, then displayed: LOADING EXTERNAL BANK…
A wave of sound crashed from his headphones. Not a synth tone—a place. A frozen factory. Rain on corrugated steel. A distant train horn bending into a low C. Jun scrolled through the patches.
SF2-01: "Rust" – A granular loop of tearing metal, pitch-shifted into a mournful pad. SF2-04: "Dial Tone Ghost" – 56k modem handshakes warped into a breathy choir. SF2-07: "The 3:17 AM Window" – Pure, aching silence with microtonal piano strings being bowed with a fishing line.
Jun wept. Not from sadness, but from recognition. This was the album that never got made. Yamaoka had poured his lost soul into this $200 workstation and then disappeared.
Over the next month, Jun used only the Korg SF2 to compose his own masterpiece. He sampled nothing else. He embraced the aliasing, the low bit rate, the way the filters chirped when pushed too hard. He called the album Forgotten Bank. The synth graveyard was a quiet place, tucked
At the album’s launch party in a tiny Shibuya club, an old man in a worn raincoat approached the DJ booth. He pointed at the laptop screen running the SF2’s output.
“You found it,” the man said. His voice was gravel and static.
Jun froze. “Mr. Yamaoka?”
The old man smiled. He reached into his coat and pulled out a second, identical Korg SF2, this one held together with duct tape and hope. “I kept the other half,” he whispered. “The bass patches. Want to hear what they sound like together?”
That night, the two machines spoke to each other for the first time in twenty years. And the rain outside the club turned into a standing ovation. Sequencer Mode The onboard 16-track sequencer is linear
The Korg SF2 never became a legend. But in the right hands—two pairs of hands, two lost souls—it sounded like forever.
If you are looking for a musical composition that highlights SoundFonts, the most famous "piece" is the demo song included with the format's definition. If you are looking for technical information (a "piece" of writing) about using SF2 files with Korg hardware, an explanatory guide is below.
Here is a proper treatment of both.
The onboard 16-track sequencer is linear (not pattern-based). It holds roughly 30,000 notes. Editing is tedious by modern DAW standards, but in 1998, being able to record a full song without a computer was revolutionary. You can save Standard MIDI Files (SMF) to a floppy disk.
