NOTE: A maximum of 10 participants can enlist to the workshop!
REGISTER: Registration tickets can be purchased here…
LOCATION: STEIM, Schipluidenlaan 12, 1062HE, Amsterdam

The workshop will consist of 4 days (weekly) where the participants will follow step by step the process of designing the controller, which acts as a MIDI step sequencer..

The workshop will teach to the participants how to develop a design with the use of open source software.


DAY One – Design the electronics of the MIDI controller.

On the first day the participants will put together all the components necessary to make the instrument work. Through the use of Fritzing (http://fritzing.org/home/) and some actual components every user will understand how our circuits works and they will put it together. All the components for building the prototype will be provided by STEIM. For programming the controller, the participant will need a computer on which the Arduino software needs to be installed. At the end of the day every user will have a working prototype of the instrument.

Instructor – Frank Baldé

DAY Two – PCB design

On the second day the participants will transform the prototype into a proper PCB. To do that the instructor will give simple tutorial about the software KiCAD, and together with the participants will design and export the actual pcb. Due to production time the participants will not have to actually produce the pcb, however the workshop will end with an introduction about the most common and accessible techniques to actually make the pcb’s designed during the class.

Every participant will need to have a computer, and KiCAD and needs to be installed on it.

Instructor – Nicolò Merendino

Day Three – Casing design

During the 3rd day the participants will design the casing of the instrument. To do that we will learn how to import a PCB in FreeCAD and design a casing around it. By doing this process the participants will learn the basic commands of FreeCAD. The workshop will end with an introduction about 3d printing and some suggestions about how to access a 3d printer to actually produce the outcome of the workshop.

Every participant will have to bring a computer with FreeCAD installed and a mouse.

Instructor – Nicolò Merendino

Day Four – Front panel design

On the last day of our workshop we will design the front panel of the music instrument. To do that we will use Inkscape and see how we can import some graphics from FreeCAD and elaborate them in order to design a correct piece to be produced with a laser cutter. To do that we will explore the potential of the open-source vector graphic software Inkscape, and then the participants will get a theoretical introduction to laser cutting and about how to access one of those machines.


Every user shall have a computer with FreeCAD and Inkscape installed, and a mouse.

Instructor – Nicolò Merendino



Frank Baldé

Frank Baldé joined STEIM Amsterdam in 1985 and started his career there as a software designer. A major influence has been his close collaboration with STEIM’s artistic director Michel Waisvisz (1949–2008), which resulted in a number of music software applications for live performance. Frank Baldé’s programming work includes MidiDraw, the real-time MIDI manipulation program The Lick Machine (together with Michel Waisvisz), the software sampling package LiSa (now RoSa), and the application junXion, which can read sensor data and process/translate it into MIDI or OSC. At STEIM, Frank Baldé actively assists visiting artists to create new instruments using software such as junXion and RoSa and hardware projects based upon Arduino.

Nicolò Merendino

“Chi Ha Ucciso il Conte?” (“Who Killed The Count?”) is a pseudonym for the Amsterdam based designer Nicolò Merendino. Nick is specialized in giving Design support to Musicians and Media Artists of any kind. Starting from an internship at STEIM in the Netherlands he already collaborated with the development of several electronic music instruments and sound installations all over Europe. Nicolò Merendino is currently working at Waag Society as Fablab Manager and Digital Fabrication Researcher
