The Spectral Processor is basically an 8-band fixed fixer bank that includes resonance control for all bands, a crossfader that mixes between the Odd (blue) and Even (lime) bands, and 2 switches that let you invert the polarity of these bands.

In this first 1.0 version, the knobs associated with the bands can only attenuate the signal for each of the bands. I do plan on improving this Block and adding new features in future but, since this is the first block I'm building, I decided to keep things simple.

The idea for this block came from the Spectral Processor that I created for my WEST// ensemble. While this one is much simpler, it's can be very effective.
This block also uses modified / simpler versions of the custom knobs I created for WEST//.

I'd highly recommend modulating the Crossfade (XFade) and Resonance (Res) knobs for more interesting results.

This block also includes 3 LEDs. The Output led visually indicates the mix between odd and even bands. The Even and Odd LEDs work as level meters for the sum of each of these groups of bands.

On a side note, I decided to release this as a Spektro Audio project just because that's what I'm planning to do with other Blocks I release in the future.

Hope you guys have fun with this one!

Awesome block! Is it possible in an update to have the bands sweep through adjacent even/odd harmonics?
