Spectraphon

The Spectraphon is a dual spectral oscillator, designed with Tom Erbe of Soundhack: each side either analyses a sound patched to its input and resynthesises it (SAM, Spectral Amplitude Modulation) or plays spectra of its own (SAO, Spectral Array Oscillator), with odd and even harmonic outputs, a sine and a Sub/CV output. FREQ and FINE tune each side, PARTIALS sets how many are heard, SLIDE and FOCUS reshape the spectrum, each under voltage control; the FM bus cross-modulates the sides, FOLLOW makes B follow or sync to A, and SHIFT steps through the arrays. The tuning beacon lights on consonant ratios.
