DESCRIPTION

Taking a massive amount of inspiration from the 4MS Spectral Multiband Resonator, this is a bank of six resonant bandpass filters which are tuned to selectable scales. The scale pitches can be manipulated and morphed to create interesting movement.

Also, not sure if you know this, but you can actually download the source code for the 4MS MSR off GitHub: https://github.com/4ms/SMR

As the former owner of the actual module, I have to say this really does a pretty decent job of getting the feel of it, although I'm sad there's no pitch CV in

For me. Spectralysis can sound like resonators or formant filter effects.

Thanks for the pointers, Jedinhopy. Those sure would be pitfalls in transcription. Even so, Spectralysis sounds like a nice phaser/harmonizer effect.

Transient smearing and phasiness are the FFT artifacts. And if no windowing with overlaps is used. Spectral leakage happens. And even frame-rate quantization occurs because of event processing at a specific pulse-clock speed. Upon sinebank additive resynthesis.

That's true, Jedinhopy. i was merely offering a view to the horizon of where Spectralysis could be, with bending the input spectrum to prescribed scales. Otherwise, an EQ profile with poles at scale intervals, and resonators, is an effective effect. And i agree with your initial comment, that content of the source influences their expression.

But (phase vocoders) sound bad because they introduce time smearing and does not sound transparent because adjacent bins randomly plays the same frequencies when they should not or the volume on all frequencies changes randomly when they don't in the original audio file. Some frequencies will get randomly phase cancelled and the others will get randomly volume enhanced.

A filter has a phase response, overlaying a phased (delayed) copy of input on itself. This creates boosts/attenuation. If modulating the centre frequency of a filter, you can get some phase modulation. Try modulating a bandpass over a sinewave. You'll hear and, if using a tuner plugin, see some pitch modulation. The faster you modulate the filter's centre frequency, the wider the pitch modulation. Depending on the filter, extra harmonics may be generated. All that said, i believe Spectalysis is not pitch shifting the input other than in the way stated. Using FFT analysis, however, does open up that possibility.

A resonator can't convert (major harmonics) into (minor harmonics). A resonator can only enhance the volume of what's already there. To re-tune a frequency. We would first need to follow that resonance volume and control the volume output of a free running sine wave. And that sine wave can be shifted in pitch. No equalizer is able to replace a resonance that it has boosted in dB to be a sine wave instead that can be re-tuned freely into any pitch the user desires. Imagine a equalizer where you select specific resonances to be converted into sine waves that can be re-tuned to any musical scale.

Updated the block to backup the tables with the structure. Moved the table files to test and it seems to work, so hopefully it's fully portable now.
