You know, like the ones in Ableton :)
Yippee! Resonators like the ones in Ableton! Except these ones have optional controls for Frequency, plus an option to receive midi note data in real time <-- Unfortunately, this feature only works in standalone mode ):
The global controls are pretty self explanatory. I've also included a visual aid to show you the scales when you're building chords and complex harmonies.
Resonators make great tools for sound design -- especially drum design -- or even for atmospheric stuff! You can route a simple noise oscillator through this effect to achieve breathy flute sounds, or maybe just plug a drum loop into it to change it up a bit.
Sorry I couldn't think of a cooler name. Anyway, have fun :)
