[sdiy] Resonator type filters

[rsdio at audiobanshee.com]

One place you might look, Ian, is Madrona Labs. The Virta plugin is a VST/AU for OS X and Windows that offers a resonant filter bank among other complementary effects.

The Formant section is where the action is. You can dial in classic, analog-style filter banks from 8 to 32 bands, or even an 256-band FFT mode. The spacing of the classic frequency bands can be shifted, stretched, or compressed in various ways. The other combined effects, like MIDI-controlled pitch shifting, help process the incoming audio to get it into shape for the format filter section. You might have to look around for some demos.

I'm having a little trouble launching my DAW due to other plugin trial versions that have expired and are causing a crash. If not for that, I would look through the Virta presets to see if there are any string synth filter setups that would help get you started. There is a thread on the Madrona Labs Software forum for Virta presets that might be a help.

p.s. In the tradition of full disclosure, I should probably make it known that I am affiliated with Madrona Labs. I do the hardware design, firmware development, and USB protocol drivers for such products as the Soundplane and the imminent Euro rack module. I am not involved in the software plugins, but their sales do fund my hardware designs indirectly, so one could argue that I have a conflict of interest. That said, I did play around with the plugin for a while when it was first released and it seems very powerful - far more than I think can be thrown together with a ton of building blocks from any other sound processing product.
