Diego Ferri is a musician, sound engineer, producer, and educator based in Berlin. He works closely with artists across experimental and electronic music - shaping recordings, designing live performances, and building the custom instruments and workflows each project demands.

He tours regularly as a performing musician, FOH and monitor engineer across Europe, Asia, and America, moving without friction between studio and stage, between established tools and innovative ones.

Trained in Bologna - recording engineer at Fonoprint, teacher at Percorsi Audio - and based in Berlin since 2007, he is embedded in the city's experimental and DIY scene, working across electronic and indie music and performing solo and in ensembles.

Software instruments

Live instrument GUITAR ENGINE

SuperCollider signal chain for electric guitar. Three parallel processing layers — CRYPT (saturation/space), TOWER (harmonic shaping), VEIL (diffusion) — each independently routable. MIDI-mapped for live performance via TouchOSC and FAD-9.

SuperCollider · OSC · MIDI CC

Granular reverb SCHAL

Live granular/reverb instrument. JPverb-based FDN architecture with three record modes — gate, manual, continuous. Used as a hardware reverb replacement at FOH on M32 and Midas consoles. FAD-9 fader-mapped.

SuperCollider · RecordBuf · TGrains

Loop recorder ROTA

N-event additive loop recorder inspired by the SOMA Rumble of Ancient Times. Variable bit depth (1–24 bit) with twelve mixing algorithms including XOR, AND, OR boolean modes. Runs on Raspberry Pi 5 as a pedalboard instrument.

SuperCollider · Raspberry Pi 5

Generative sequencer IRAMA ENGINE

Zero-sum shared resource sequencer rooted in Javanese gamelan irama theory and motorik krautrock. Speed and volume share a fixed budget across tracks. FREE (probabilistic) and LOCK (Euclidean) modes per track. SuperCollider engine with browser and Teensy hardware interfaces.

SuperCollider · Teensy 4.0 · WebMIDI

Browser sequencer ADDSEQ

Additive sequencer prototype where time is constructed by summing absolute event durations — no BPM, no grid. Inspired by Turkish aksak rhythms and live coding practice. Microtonal, Hz-based pitch lists. Drag-to-reorder events.

HTML · WebAudio · WebMIDI

Installation MUSIKTRUHE / SOL

Generative sound installation running inside a vintage German music cabinet. Solar elevation and live temperature data drive FM synthesis. Four temperature bands map to distinct timbral registers. Fully autonomous — no external control.

SuperCollider · Raspberry Pi · Open-Meteo API

Live scoring system SCORE CONTROL

Node.js application for conducting improvised film soundtracks with large ensembles. Musicians see the film or a graphic score on their own screens plus real-time cues pushed by the conductor. Runs over a dedicated Raspberry Pi OSC access point — no internet required, works in any venue.

Node.js · OSC · Raspberry Pi AP

Electronics & instrument building

Hardware sequencer IRAMA MACHINE

Physical implementation of the IRAMA ENGINE concept. Teensy 4.0 with OLED display, encoders, and button matrix. MIDI out confirmed, Euclidean and probabilistic per-track modes. Second hardware version in development: ratcheting, melodic channel, proper enclosure.

Teensy 4.0 · MIDI · Perfboard

Synthesis & repair Synthesizer restoration

Repair and restoration of vintage synthesizers and keyboards. Roland SH-2000 (PSU rebuilt, carbonised trace fault resolved), Roland JX-8P, Roland JX-10, Roland S-550. Korg M-500, M-700, M1. Yamaha SY77, SY99. Kawai K1, K4, Q80. ELKA ER33 (full recap, regulators). Nord Modular G1. Waldorf Blofeld, Pulse+. Jomox MBase 11, XBase 09. And many more.

Utilities TRS MIDI merger & tools

Arduino Nano-based TRS MIDI merger built on perfboard using 6N137 optocouplers. Part of an ongoing practice of building small utilities — interfaces, adapters, and signal routing tools — for studio and live contexts where commercial solutions don't fit.

Arduino · 6N137 · CH340

Midified instrument Casio SK-1 MIDI retrofit

Full MIDI retrofit of the Casio SK-1 sampler keyboard, now integrated into the studio MIDI chain on channel 1 alongside the Virus PowerCore. Key scanning matrix read and mapped; velocity sensitivity added.

MIDI · Matrix scanning · Studio integration

Network infrastructure OSC access point

Portable wireless access point built on Raspberry Pi 3B, purpose-built for SCORE CONTROL and large ensemble sessions. Fixed AP on wlan0, MAC-addressed DHCP leases for all performer devices. No internet required — self-contained, deploys in any venue in minutes.

Eigenklang

A music course that uses electronics as its material. Aimed at children and young people aged 8–16, Eigenklang teaches sound, electricity, and creative thinking through hands-on building — circuits, sensors, instruments, and noise-making objects.

No prior knowledge needed. Sessions run in schools, cultural institutions, and community spaces across Berlin. Groups of up to twelve participants. German and English.

The programme is grounded in the idea that building your own instrument changes your relationship to sound — and to the idea of what a musician is.

Get in touch →

Curriculum — 8 sessions

01What is sound? Microphones, speakers, signal flow
02Electricity basics — voltage, current, resistance. First circuit
03Oscillators. Building a simple tone generator
04Sensors as input — light, touch, distance
05Noise and distortion as material, not accident
06Recording and playback. Tape, memory, loops
07Free build — own instrument concept and prototype
08Performance and presentation

Child Protection Policy

Eigenklang Workshop Programme - Safeguarding Framework

The Eigenklang programme works with children and young people. The protection of all participants is the highest priority. This framework applies to all programme formats and is reviewed regularly.

Principles

The wellbeing and safety of participants comes first. All workshop formats are designed to ensure a safe, respectful, and supportive learning environment. Discrimination, physical or psychological harm are not tolerated.

Instructor qualifications

Extended criminal record check (erweitertes Führungszeugnis, § 72a SGB VIII) - held and renewed regularly. First aid qualification - refreshed every two years. Several years of experience working with children and young people in cultural and educational settings.

Supervision and safety

Maximum group sizes are set per age group and format. Children under 12 are taught only in the presence of an additional adult supervisor provided by the booking institution. Tools and components are used in an age-appropriate manner; risk assessments are documented.

Consent and information

Parents and guardians receive full written information before the start of each course: programme content, materials, safety measures, and photography policy. Photos for public communications are only taken with explicit written consent.

Incident procedures

In cases of suspected child endangerment, the Berlin Child Protection Act is applied and relevant authorities are notified. A clear internal reporting procedure is documented and available on request.
