Just spotted this today – and it’s not going to be available for a while, July maybe, and there’s not even anything to listen to yet, and it’s just a Eurorack module – BUT it looks absolutely amazing!
The Basics: You feed it an audio stream, anything from something simple to a complex mix. It spectrally analyzes this and the lets you additively resynthesize and recreate the harmonic structure of the sound while you modify the basic elements of that structure. This technique has been around for a while, but the implementation Rossum has put together here looks very promising.
The module allows you store presets as well as store ‘freezes’ that can be modified and used like an oscillator source.
There is an article here at Synthtopia that discusses it.
From the description at Perfect Circuit:
PANHARMONIUM FEATURES
- Spectral resynthesizer in Eurorack format
- Analyzes incoming audio and resynthesizes the analyzed spectra with an internal oscillator bank
- Transforms any input source into a re-synthesized sound and allows for ample spectral manipulation
- Slide parameter defines rate of analysis, and can be tempo synced or run freely
- Center Freq and Bandwidth controls determine range of frequencies to be analyzed
- Freeze control for sustaining current analyzed spectrum
- Voice parameter for selection of number of oscillators used for resynthesis (from one to 33)
- Blur control adds lag to the resynthesis, creating smearing effects between spectra
- Variable resynthesis Feedback for evolving, as-of-yet unheard sounds
- Waveform, pitch, glide, and mix controls for oscillator bank
- Waveforms include standard waveforms as well as special crossfading wave shapes
- Drum Mode optimized for superior transient response
- Spectral Warping function enables decoupling of individual harmonics from the analyzed overtone structure for inharmonic warping effects
- Global preset memory and Spectra memory
