Spectrum is a Digital Eurorack module for intuitive microtonal sequencing. It bypasses standard MIDI constraints, enabling real-time EDO (Equal Division of the Octave) modulation through a high-precision trackball and mechanical keyswitch interface. The design facilitates neurodiverse melody through organic, improvisational workflows. It features dynamic EDO scaling and a “thumbing” mode (popularized by Toto’s Steve Porcaro) for freeform, syncopated sequencing, drawing on the tactile ergonomics of Oberheim DSX-style hardware (1981). At PIFcamp, the focus will be on refining control algorithms and optimizing the interface for high-density, real-time melodic manipulation.
Omar Mashaal (Australian Tactile Instruments) develops hardware for experimental performance. With 25+ years in software development, live coding and embedded systems, his work centers on microtonality, physical computing, and non-standard tactile interfaces.
