What is Femur (femurdesign.com)?
Updated
Femur (femurdesign.com) is the personal portfolio site of Luke Phillips, a design engineer and musician who builds expressive, accessible music tools across software, hardware, and the web. The site's stated purpose is "making musical things that anyone can play," and it serves as a project index rather than a product or store — you visit it to explore what Phillips has built and to find links out to each instrument or project.
Who is behind the site
Phillips describes himself as a software engineer and musician working across music technology, creative tools, and AI. He notes more than a decade of building interactive instruments and learning products, from browser-based synths to cross-platform apps and spatial hand tracking. His stated design interest is making complicated musical ideas feel immediate and playable, with the technology getting out of the way quickly. His background spans frontend and UX engineering, creative coding, audio, MIDI, and real-time interaction.
What the site showcases
The homepage lists five projects, each with a short description and an outbound link.
| Project | Type | What it is |
|---|---|---|
| Funputs | Audio plugins | A suite of MIDI instruments (2026) that replaces knobs, sliders, menus, numbers, and text with space, colour, movement, and shape |
| ROLI | Software engineering & R&D | Work from 2019–2026 across piano learning, interactive notation, audio, hardware integration, and conversational AI |
| BlokDust | Browser instrument | An open-source, browser-based music-making environment (2015) |
| Omni | Web instrument | A tactile way to play and learn musical scales from cultures around the world |
| Theremin | Web instrument | A multi-touch Web Audio synthesiser (2014) for shaping waveforms, delay, feedback, and scuzz in the browser |
Funputs in more detail
Funputs is the most recent project listed (2026). It's a suite of MIDI instruments built around the idea that most music software relies on knobs, sliders, menus, numbers, and text — and that much of that could be replaced with space, colour, movement, and shape. Three named components are described:
- Comet — an expressive XY pad
- Orbit — tunes you to any scale
- Cluster — generates chords
You can control them with a mouse, or pair a phone or tablet for wireless multi-touch control.
ROLI work
At ROLI, Phillips worked across piano learning, interactive notation, audio, hardware integration, and conversational AI, including AI Music Coach and Airwave. One concrete detail: he integrated computer vision into ROLI's platforms to give real-time guidance on finger positions for piano learners, and to let musicians shape sound expressively through gesture.
Browser instruments
BlokDust, Omni, and Theremin are all playable in the browser. BlokDust lets you join blocks to build synths, process your voice, remix samples, and create self-playing systems. Omni offers a pitch constellation, harp, effects, harmonies, and loop recording for exploring scales from different cultures. Theremin is a multi-touch Web Audio synthesiser for shaping waveforms, delay, feedback, and scuzz.
What the site does not offer
The page evidence contains no pricing information, no payment platforms, and no login or account requirements. Nothing on the site indicates whether the tools are free, paid, or gated — so treat availability as something to check on each linked project rather than assuming. The site itself functions as a portfolio and directory; the actual instruments live at their own destinations.
When this site is useful to you
- You want to try browser-based music tools without installing anything — BlokDust, Omni, and Theremin are the direct starting points.
- You're interested in alternative interfaces for music software and want to see how Funputs approaches control through shape and colour instead of knobs and numbers.
- You're researching music technology, accessible instrument design, or AI-assisted music learning and want to see a practitioner's body of work.
- You want to get in touch with Phillips — the site provides GitHub and contact links.
If you're looking for a product to buy, a download page, or documentation, this isn't that kind of site. It's a map of one designer's work, with each project linked out for you to explore on its own terms.
