Jeroen Tel
Commodore 64 Music Composer
Jeroen Tel, Commodore 64 Music Composer
The Dutch SID prodigy who co-founded Maniacs of Noise and became a professional composer at sixteen, producing some of the most celebrated soundtracks in C64 history.
Jeroen Godfried Tel was born on 19 May 1972 in Eindhoven, the Netherlands. He bought his first Commodore 64 at the age of twelve and immediately began experimenting with the SID chip, first through BASIC programs and then through tools like Soundmonitor. What started as curiosity quickly became mastery.
In 1987, at fifteen, he met Charles Deenen and together they founded Maniacs of Noise. Their first professional music routine, demonstrated at the PCW trade show, led directly to a commission from Hewson Consultants for Battle Valley. Within a year, Tel was one of the most sought-after composers in European games.

Jeroen Tel: A C64 Professional at Sixteen
By the time he turned sixteen, Tel was already composing commercially for some of the biggest names in European games publishing. His soundtracks for Cybernoid and Cybernoid II established him as a composer who could deliver technically advanced music with genuine emotional impact. Publishers including Hewson, Thalamus and Ocean all sought his work.
After the C64 era, Tel extended his range to other platforms: Amiga, NES, Super Nintendo, SEGA Mega Drive, SEGA Saturn, Game Boy and PlayStation. His NES work on Robocop 3 was reportedly produced in a single night, a demonstration of the speed and professionalism that defined Maniacs of Noise at their peak.
Tel's full catalogue is documented on the C64 Scene Database, where his work continues to be studied, covered and celebrated by the global retro gaming and chiptune communities.

Jeroen Tel's Iconic C64 Works
Tel's catalogue spans games across multiple years and publishers. Each track demonstrates a different facet of his talent: melodic invention, rhythmic drive, atmospheric depth and technical precision. His thirteen entries in the High Voltage SID Collection include two in the all-time top ten.
Cybernoid (1988)
High-energy soundtrack with rapid arpeggios and driving bass lines that set the tone for the shooter perfectly.
Cybernoid II (1988)
Widely regarded as his finest achievement: complex melodies, innovative SID techniques and an orchestral depth that still stands up today.
Hawkeye (1988)
Atmospheric and sweeping, with a distinctive blend of melody and rhythm that feels larger than three voices should allow.
Myth: History in the Making (1989)
Epic music matched to a mythological setting. One of his most ambitious compositional achievements on the platform.
Golden Axe (1990)
A memorable port of the arcade classic, with dramatic and heroic tones that hold up well against the original.
Supremacy (1990)
A strategic, atmospheric soundtrack that adds genuine depth to the gameplay without ever dominating it.
Cybernoid II
Released in 1988 by Hewson Consultants, Cybernoid II remains the benchmark by which C64 game music is judged. Tel's soundtrack combines complex melodic lines with sophisticated SID techniques to produce a piece that sounds larger and richer than the hardware constraints would suggest possible.
Jeroen Tel's Turbo Outrun on the C64
Turbo Outrun was released in 1989 by U.S. Gold, based on SEGA's arcade racer. The game puts the player behind the wheel of a Ferrari F40, racing across American cities from New York to Los Angeles against the clock and rival drivers.
Tel's soundtrack captures the speed and energy of the race with a driving, rhythmic composition built from rapid arpeggios and pulsing bass lines. The music pushes the SID chip in exactly the direction the gameplay demands, creating an immersive experience that made the C64 version stand out despite its hardware limitations.
The Turbo Outrun title music is one of Tel's most enduring compositions and a regular presence in SID music collections and retro gaming playlists worldwide.
How Tel Composed for the SID
Melodic Sketching
Tel began by working out melodic ideas in his head or at a keyboard before writing a single line of code. He thought in terms of atmosphere and context, tailoring each piece to the mood of the specific game rather than writing generic music.
6502 Assembly Programming
Rather than using standard music editors like Soundmonitor, Tel composed directly in 6502 assembly language. He defined notes, frequencies, volumes and effects using hexadecimal values, giving him complete control over the SID chip that no editor could match.
Custom Sound Drivers
Tel wrote his own music player routines from scratch. These custom drivers were more compact and efficient than commercial tools, consuming minimal CPU time and RAM. With the C64's 38,911 free bytes of RAM, efficiency was not optional, it was essential.
Arpeggio and Voice Management
The SID chip had only three voices. Tel used rapid arpeggios, cycling through chord tones on a single voice at high speed, to simulate harmony while freeing the other two voices for bass lines, drums and counter-melodies. The result was a deceptively full, rich sound.
Testing and Fine-Tuning on Real Hardware
Every composition was tested directly on the C64, because the SID chip's filter behaviour and oscillator characteristics varied by chip revision. Tel adjusted waveforms, filter sweeps, ADSR envelopes and vibrato rates by ear until each track sounded exactly as intended.
Tel programmed the SID chip directly in 6502 assembly, bypassing standard music editors entirely for maximum control.
Jeroen Tel's Inspiration and Influences
Tel was inspired by the composers who came before him on the C64. He has cited Rob Hubbard, particularly his work on Thing on a Spring and Crazy Comets, as a formative influence. Martin Galway and Ben Daglish were also composers he admired and studied closely.
The demoscene played a significant role in shaping his approach. Through demo productions he experimented freely with sounds and techniques outside the pressure of commercial deadlines, which fed directly into his game work. Filter sweeps, ring modulation and complex envelope shaping all became signature elements of his style.
His pseudonym WAVE reflected his interest in waveform synthesis and the sonic possibilities of the SID chip beyond conventional melody and harmony. He approached the chip not just as a music instrument but as a synthesiser to be explored.
Tel Me More and the Retro Community
In 2015, Tel launched the Tel Me More crowdfunding campaign to produce remixed versions of his classic C64 compositions. The campaign drew significant support from the retro gaming and chiptune communities, reflecting the enduring affection for his work more than two decades after the original recordings.
The campaign was formally closed in February 2022, but Tel confirmed in June 2023 that he still intended to complete the project. A track was released in 2020 during the campaign's active period. His continued engagement with the community shows that the connection between Tel and his audience has never really broken.
Tel remains active at retro events and chiptune gatherings. The interview below, produced by the Dutch technology publication Tweakers, gives a rare insight into his recollections of the C64 era and the techniques behind his most famous work.
