Synthetech Sound has set free Spectra, a powerful additive resynthesizer Rack Extension for Reason.

The synth features a drawable sound spectrum, filters and waveforms, drawable harmonic modulators, harmonic envelopes, 3×16 stage MSEGS, and a spectral analyzer.

Spectra’s ability to analyse and resynthesise any periodic, harmonic waveform via its inbuilt spectral waveform analyser means you may never exhaust Spectra’s sound creation possibilities.

If you have ever wanted to sculpt sound by drawing your harmonic spectrum, waveform or drawing a spectral filter response then Spectra may be what you’ve been waiting for.

Spectra is available to download to Reason 9.2+ owners at Reason Studios.
