Ensoniq Ts-10 Soundfont -sf2- < FREE >
Leo was fired.
Sonic Foundry released the SoundFont on a CD-ROM in April 1999. It cost $99. It sold 400 copies. The reviews were tepid: "Too big for consumer sound cards," "The loops aren't perfect," "Just buy a used TS-10."
But the internet is a digital graveyard that refuses to stay dead. In 2002, a bedroom producer in Ukraine uploaded “TS10_Legacy.sf2” to a forgotten FTP server. In 2005, a tracker forum in Sweden embedded it into a keygen. In 2011, a sample library curator on Reddit named VintageSamples_Archive found a pristine copy on a Zip disk at a flea market in Berlin.

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.
Leo smiles. “That’s it,” he whispers. “That’s the sound.” Leo was fired
The SF2 format was a miracle of 90s programming. Unlike a simple sample dump, an SF2 file contained a complete virtual instrument: the raw audio samples, a voice-stealing algorithm, low-pass filters, LFO routings, and a multi-stage envelope generator. But the TS-10’s magic wasn’t in the raw waves—it was in the behavior : the way a flute sound would morph into a choir if you held the key down, the way aftertouch added not just vibrato but a subtle distortion, the way the “Funk” wave in the Transwave section would cycle through eight different attack transients depending on velocity.
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. It sold 400 copies
The TS-10’s samples were not perfect. To save memory (the TS-10 had only 6MB of factory ROM), Ensoniq’s engineers used clever, short loops. But translating a hardware loop to an SF2 loop was a form of torture. Leo would load a sample into Sound Forge 4.0 . He’d zoom into the waveform, looking for the "zero-crossing"—the exact point where the wave’s voltage returned to nil. He’d find a 200-sample cycle that sounded seamless on the TS-10. But in the SF2, it would click. Pop. Buzz. One night, working on the "Electric Grand" loop, Leo heard it—not a click, but a ghost. A faint, repeating artifact of the original recording session Ensoniq had used back in ’96: a distant car horn, looped into eternity. He isolated it. He named the file “TS10_EGrand_GHOST.wav” and kept it as a reminder that hardware has secrets software never can.
