1972 Exploratory Stereophonic Spectral Lattice Network

Budapeszt is a stereo dual spectral processor built around the interference of resonant structures. It features two independently tunable comb-type filters with six distinct modes. Each filter has its own set of controls, with two separate triangle LFO's providing internal modulation (with free and synced operation, and an envelope follower mode on top). The real magic happens in the interference between two stereo filters. The overlap of two resonant structures weaves a spectral lattice: a complex grid of peaks and voids. The final geometry of that lattice is determined by the relationship between the channels rather than by either one in isolation. To encourage experimentation and for even more sonic flexibility, multiple feedback paths are available, including cross-coupled feedback between the filters. There's also a feedback phase inversion switch for each filter.

Filter modes include delay-based, phase-based, and filterbank-based approaches to shaping the frequency domain. The first mode draws on a signal model inherited from Xaoc Devices Samarkanda, enabling artifact-free pitch behavior across the full frequency range. The remaining modes distribute resonant energy in a wide range of ways, resulting in great variation of effects. That being said, more familiar results, like flanging and chorus, are also easily attainable - delivered by Budapeszt with unusual precision.
