Diego Ferri - Musician, Sound Engineer and Producer in Berlin

SuperCollider processing engine for electric guitar. Three parallel processing layers: CRYPT (tape compression, digital delay), TOWER (distortion, octaver), VEIL (granular processor) - each independently routable. MIDI-mapped for live performance via TouchOSC and MIDI controller.

Demo

Live granular/reverb instrument. JPverb-based FDN architecture with three record modes - gate, manual, continuous. Mapped to a Korg nanoKontrol 2 and used as outboard reverb at FOH consoles.

Monophonic performance synthesizer. Four voices with twelve mixing algorithms, including XOR, AND, and OR boolean modes, driven by an N-event additive looper that controls the voice gates directly.

Runs headless on a Raspberry Pi 5, with dual mono output or on a Macbook M1 with first-order Ambisonics output (FOA / B-format).

Four channels encoding a full 3D sound field, decoded live to binaural or loudspeaker rigs via SuperCollider's ATK, so the instrument can be spatialised and moved around a room as part of the performance itself.

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

Open

Sequencer prototype where time is constructed by summing absolute event durations. Inspired by Turkish aksak rhythms, early Moog sequencers and coding. Fixed pitches or microtonal, Hz-based pitch lists can be linked to each event. Supports additive and multiplicative modifiers.

Open

Generative sound installation running day and night inside a vintage German music cabinet. Solar elevation and live temperature data drive FM synthesis based on 10 composed chord progressions that follow the seasons. Four temperature bands map to distinct timbral registers. Fully autonomous - no external 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.

A 24-channel mobile recording system built to move anywhere with a power outlet. Good-quality preamps and converters throughout - API, AML, Hairball, Antelope, Focusrite. The system operates silently to enable location recording.

Open

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

Repair and restoration of vintage synthesizers and equipment. 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). Yamaha DM1000, Allen & Heath Xone:92, Behringer X32, Midas M32, Nord Modular G1 and many more.

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.

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.

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.
