The instrument

Recently we ported our Touch instruments to the web, and you can play one right here. Press Play it, then touch the pads. This is the instrument your manual will be built on.

Our instruments, running in your browser. Pick one at the top. Use headphones for the best sound, or open it full screen.

The assignment

You just played it without a manual. Now imagine it teaching you as you play. We want to take the web instruments to the next level with an interactive manual: an educational layer on top of the instrument itself. Players start with the basics and, as they go, discover hidden features and performance techniques, right on the instrument they are playing.

You will:

  • research how musicians learn new instruments, and test your ideas with real players
  • develop the concept and the learning journey, from first sound to advanced techniques
  • design and prototype the manual, iterating on feedback from our team and from users
  • deliver a working prototype on the web lab, plus the design files and a short handover

This is a graduation project, so we shape the design question together with you and your school supervisor.

Who you are

You are both a designer and a musician, so designing a cutting-edge interactive manual for electronic music instruments sounds like a dream job.

You are dedicated and like a good challenge. You can design, iterate and work with feedback from stakeholders and users. You always look for ways to improve and refine your concepts and designs.

Your portfolio shows a mix of work, from concept development to prototypes and experiments, and you can turn your concepts into professional-looking designs.

You might do some coding, and you are comfortable working with AI tools (LLMs) to get your ideas working. You speak English; Dutch is a bonus.

What we offer

  • Real work on instruments that musicians around the world play, which you can show in your portfolio. Our work is open source, so what you make is public.
  • Daily guidance from Roey Tsemah, designer and founder, as your company supervisor.
  • An internship allowance of €300 to €500 a month, depending on your skills and experience.
  • A small, creative team: 2 to 4 people at the studio each day. We each work on our own projects and brainstorm through the day and over coffee.
  • A studio 5 minutes’ walk from Witte de Withstraat. 4 to 5 days a week, mostly at the studio. Bring your own laptop.

Superbooth, Berlin

Every May we present our instruments at Superbooth in Berlin, a big synthesizer fair where we have a strong presence. Superbooth 2027 runs 6 to 8 May. If your internship runs in May, you may be able to join us at Superbooth. It depends on availability and budget, so we can’t promise it. If you join, we pay your travel and stay.
