We develop hardware and software for embedded systems.

Based on our experience in the field of audio electronics and digital signal processing we offer development services for embedded systems from prototype to serial production.

Projects

We have contributed to the development of these devices:

Midilooper

Midilooper is a performative loop station that operates on MIDI messages. In contrast to looping in the audio domain where a lot of musical information has already been merged, this approach provides musicians with more flexibility to morph their loops. This way midilooper is crossing the gap between looping and sequencing.

For this device, we developed two special input circuits. One is a control voltage input that can be reconfigured through software into an interface for a passive pedal switch. The other one is a standard compliant MIDI TRS input that can also be used as a modular level clock input.

The firmware was developed completely by us. Its core feature is a storage structure for MIDI information that allows fast read and write access, arbitrary track lengths and flexible distribution of storage capacity between tracks. Additionally, it can be serialized to non-volatile memory allowing for fast and seamless switching between banks.

Thyme Effects Processor

Thyme is an experimental delay-based effects processor.

As the instrument focuses on the exploration of the space inbetween classical delay based audio effects, we had to develop a signal processing chain that is both flexible to control and efficient in terms of processing power.

Next to firmware development, we supported hardware development and created a semi-automatic testing rig for production.

Komplex Sequencer

A quad hardware sequencer controlling synthesizers via CV/Gate and MIDI signals.

Being responsible for firmware development, we were challenged by allowing near endless possibilities of CV-control while not compromising on timing precision.

To achieve a high precision voltage output without extending production times, we developed an automated calibration routine.

Toc-One

Toc-One is a toolbox for generating electro-acoustic music that we developed together with robotic music artist Sonic Robots. It consists of multiple beater heads that can be controlled through MIDI messages.

To be usable live on stage, the beaters needed to be relatively powerful while being connected to the central control unit only through long standard XLR microphone cables.

We contributed to the project in terms of circuit design and firmware development.

Strom Power Supply

Strom is a series of modules for powering eurorack modular synthesizers.

The main goal of the development process was to design an affordable power solution while not compromising on safety measures and the quality of the provided output voltages.

We built custom test equipment to aid the development process and help quality control in production.

Strom Mobile

The Strom Mobile is a voltage converter made for powering electronic instruments using common USB power banks.

As the quality of power bank output voltages can differ drastically, we put a lot of effort into providing a clean output voltage under all load conditions.

Next to the ciruitry and pcb of the product itself, we developed a test rig to speed up quality control.

Field Kit

The Field Kit is an experimental tool for making music with everyday objects.

We undertook development of the signal interface whichs transforms sensor data into gate and CV signals. With the intension of animating people new to electronics to play with a variety of sensors, we put a strong focus on hardening the circuitry against accidental misconfiguration.

Additionally, we developed soft- and hardware to automate parts of production and quality control.

Field Kit FX

The Field Kit FX is an CV-controllable multi-effect unit.

While developing the firmware and circuitry for digital audio effects and analog signal routing as well as the internal power supply, we put a lot of effort into maintaining signal quality in a highly integrated mixed signal application.

Field Kit Sensors

The Field Kit Sensors are an extension to the Field Kit, enabling the use of environmental signals within the process of sound design.

Being used by people unfamiliar with electronics, the raw data from different types of sensors has to be preprocessed to expose a common interface and the circuits had to be hardened against accidental misuse.

Modular Case

A case for eurorack modular synthesizers.

We designed the case to be a modular system in itself and to keep production costs as low as possible, while not compromising on material selection.

Philosophy

Having both a background in engineering and experience in developing devices for artistic and creative purposes, our goal is to explore new ways of leveraging the power of technology without compromising well-proven engineering guidelines.

We transform your idea into a proof of concept that is further evolved through an iterative, feedback-driven process into a finished product ready to be produced and tested efficiently.

We strive to adapt state-of-the-art techniques from software engineering to the world of embedded software to produce quick and reliable results.

We use rapid prototyping technologies to allow testing of devices in their future environment at an early stage of development.

We rely almost entirely on open-source software tools and deliver our work in open file formats that do not force you to use expensive tools or lock you to a specific operating system.
