4Bit Studio

Hello, my name is Ulrich Troyer. I am a composer, musician and sound designer who is running the 4Bit Studio since 2001. I've specialized in using analogue synthesizers and effects combined with traditional instruments and everyday sounds to create sound design & music.

The black & white picture shows a portrait of Ulrich Troyer, behind him you can see a section of his 4Bit Studio - the background is  blurred by the Depth-of-Field blur effect: from left to right you can distinguish turntables, cables, a mixer,  different monitor-speakers, a laptop, a modular synthesizer, on the wall in the background you can see acoustic absorber panels. The picture was taken by daylight by Viennese Photographer Eva Kelety.

Instruments & Tools

My favorite tools for creating music & sound design are analogue synthesizers and keyboards. I love to add reverb, filter- and delay-effects to create organic textures and surprising sound effects.

I play classical, acoustic and electric guitar, electric bass, piano and various percussion instruments, objects and gadgets to create sounds.

When recording foley work and sound design effects, I like to improvise to the picture and use these recordings as basis for more detailed edits to the picture later on. The final sound design is a combination of live-recordings and synthesized sounds, multi-layered and manipulated in the computer to sculpt the final organic and unique sound effect.

My recording setup includes a collection of large and small diaphragm cardioid microphones, various dynamic micorphones, a large diaphragm tube microphone, a phantom-powered ribbon microphone and various hardware pre-amps, EQs and compressors.

“Absolutely fab.“
- The Guardian on LOOPIMAL

“BANDIMAL is the world’s cutest app for kids to make music“
- Fastcodesign on BANDIMAL

- Forbes on BANDIMAL

“And parents can exhale: Austrian composer Ulrich Troyer designed and composed all of BANDIMAL’s sounds in the key of C and around the pentatonic scale, imbuing all its outputs with a pleasant quality.“

“Superb visuals & audio-loops!“

“Slaptastic soundeffects“

“Packed with effortless charm!“
- Cartoonbrew on MIXIMAL

“BANDIMAL is a terrific app for young kids to experiment with music and rhythm. With an intuitive interface, kids can create great-sounding tunes without needing to possess any musical knowledge. The melodies have an upbeat, electronic feel, and kids will surely giggle at the sight of the animals getting stretched and squished to match the beat. Highly recommended.“
- Geeks With Juniors, Blog

“The other bit of brilliance inside the app is that you can’t make anything that sounds bad. Ulrich Troyer designed the entire sonic experience around the sharps-and-flats-less key of C and the pentatonic scale (which features five notes rather than the typical seven you know from minor or major scales). As a result, creating dissonance is impossible. Such a framework takes rule-bending, jazz creations off the table, but then again, it lets you score a whale, panda, and a chicken together with ease. At the end of the day, what could be more fun than that?“
- Mark Wilson on BANDIMAL, Fastcodesign
