Leo Focht is 73 now. He builds model ships and has perfect hearing for his age. He does not own a computer. But once a year, his grandson brings a laptop over. The grandson, a music producer named Leo III, loads up a DAW and pulls up a file. It’s always the same file. He plays a middle C. The "DreamPad" swells, its noisy, imperfect loop cycling forever, the ghost of the TS-10 breathing through a 26-year-old SoundFont.
Today, the Ensoniq TS-10 SoundFont lives in the dark corners of thousands of hard drives. You can hear it if you know where to listen. It’s the warm, unstable pad on that lo-fi hip-hop track with 2 million YouTube views. It’s the brittle piano on that indie game soundtrack that made you nostalgic for a childhood you never had. It’s the bass in that techno track that shakes the subwoofer at 3 AM in a warehouse in Detroit.
Leo smiles. “That’s it,” he whispers. “That’s the sound.” Ensoniq TS-10 SoundFont -SF2-
Leo did the unthinkable. He bought a used TS-10 from a pawn shop on Santa Monica Blvd using his rent money. He spent 72 hours straight re-sampling. He survived on cold pizza and Jolt Cola. On the final hour, he triggered a low C on the "ResoReese" bass patch. The sound was a perfect, snarling, detuned monster. He saved the final SF2 file. Total size: 148MB. He named it .
Leo’s workstation was a beige Pentium II running Windows 98. His tools: a Turtle Beach Pinnacle sound card with a proprietary S/PDIF input, a copy of Chicken Systems Translator , and a mountain of pirated RAM. His process was monastic. Leo Focht is 73 now
To the uninitiated, the TS-10 was just a 61-key workstation synth, its grey chassis unremarkable beside a bank of Moogs and Prophets. But Leo knew better. Inside that unassuming shell lived a 24-bit polyphonic aftertouch keyboard, a proprietary synthesis engine called "TS" (Transwave Synthesis), and a 16-track sequencer that had powered half the R&B hits of the late 90s. Its sound was its secret weapon—a gritty, warm, almost tactile quality. The piano had a wooden knock; the strings breathed with a noisy, imperfect vibrato; the pads bloomed like flowers in slow motion.
The SF2 format allowed for up to 27 different modulators. The TS-10 had 16 real-time controllers. Leo spent two weeks just mapping the aftertouch to filter cutoff response. On the TS-10, it was exponential—a light touch added warmth, a hard squeeze added bite. In SF2, he had to build a piecewise linear curve. He failed. Then he failed again. Finally, he wrote a custom script in an ancient version of Python that brute-force calculated 128 breakpoints. At 4 AM on a Tuesday, he played the converted patch. He pressed down on his MIDI keyboard’s aftertouch. The sound screamed . He cried. Just a little. But once a year, his grandson brings a laptop over
Leo’s mission, assigned by a boutique sample library startup called Sonic Foundry , was impossible: translate the soul of the TS-10 into the cold, sterile language of the SoundFont 2.0 (.SF2) format.
