Hardware and software audio instruments
The software version of MODEL 601 translates the Vienna Audio complex generator into a VST3 instrument. The prototype is designed as a 10x polyphonic version of the system, bringing the MODEL 601 architecture into a software environment while preserving its focus on wavetable transformation, modulation and timbral control.
The video documents the V-PRO function, where a central waveform can be pushed toward two processed extremes and all intermediate timbral states, interacting with the Spike and stretch functions.
Recent Vienna Audio ports developed as independent VST3 instruments and processors, translating the original TouchDesigner prototypes into dedicated real-time DSP systems.
A polyphonic MIDI reharmoniser built from a network of 25 serial transformations. Source and Intelligent modes combine scale mapping, transposition and voice-leading continuity for clips, chords and live performance.

A neo-Riemannian MIDI generator built around an interactive Tonnetz. P, L and R transformations and their N, S and H compounds drive harmonic paths, while automatic voice leading realises each triad across three to eight voices.

A quad morphing filter processor with four parallel nodes, amplitude, bandwidth, frequency and modulation-index control. A three-dimensional XY stick, staged states and host, MIDI or external control turn the filter bank into a performable timbral space.
View instrument ->
A dual morphing wavetable generator whose two voices combine sine, power and sign shaping with warp and X/Y folding. Visible waveforms, Dual mode, synchronisation and unison make complex spectral transformations directly playable.
View instrument ->
A 120-harmonic waveform generator for composing frequency, amplitude, phase and waveform distributions. Editable maps, controlled random evolution, bank restore and DAW/CV controls shape dense spectra as evolving musical structures.
