SSF Dipole Stereo Filter Spectral Crossfade

The SSF Dipole Stereo Filter has quickly become my favorite module in my rack for two reasons: sound quality and versatility. When I first got it, I mostly just messed around with the extremes, sending it tons of low frequency and audio-rate modulation and really enjoying exploring the variable bandpass and notch modes. Aside from a few patches using it as a pinged quadrature oscillator, I kept it pretty aggressive as a dual filter for one sound source exploring the spectral stereo field with each respective dipole output.

For my most recent patch to get ready for my show at Modular Manifestation III in Pasadena tonight, I decided to keep it more straightforward, originally using each side separately for a different voice in the patch. This led me to using it as a spectral crossfader between the two filters with very different inputs, a very simple way to use the module that I completely neglected to consider. For side A, I had a SSF ZPO FM bass voice going through both poles set to LP, and for side B, I had a hi-hat esque sound using a SSF Quantum Rainbow noise source ring modulated by an Intellijel Dixie II pulse wave with both poles set to HP.

While by chance playing with the macro filter control for the dipole in the setup, I realized that it could work fading between Side A and Side B as an opportunity to create even more movement in the patch. You might say ok captain obvious, that's a very clear possibility looking at this module. But I point this out because I loved the potential of the results, and with a module this deep, I'm sure I'm not the only one who just realized what a smart and simple design choice to allow for this purpose.

Just as exciting to me is the possibilities for more control with my new favorite CV source controllers in my system, the Intellijel Tetrapad

+ Tete touchpad system and Intellijel Planar II joystick. The Tetrapad + Tete in this case is controlling a Mannequins voice in notes mode with extra processing from a MI Clouds. The rest of the percussion is all courtesy of heavily processed SSF Entity Bass Drum and Percussion modules, and all of it is sent at variable intervals to a 4MS Dual Looping Delay for more textures and rhythms to bring in. Here's a little clip of the results and the patch, plus a bonus video of my first play with the Tetrapad + Tete last week below that as well.
