Nekyia Circuits' Ceremony — Twin Peak Filter/Resonator Inspired by Rob Hordijk, From Lowpass Filtering to Plucky Resonant Bells
Nekyia Circuits' Ceremony is a dual analog 18dB resonant filter inspired by Rob Hordijk's TwinPeak design. The filter morphs continuously from a lowpass response to a twin peak bandpass configuration using the LP/BP knob — at minimum, you're hearing only Frequency A, while turning it up gradually introduces Frequency B as a second resonant peak. The two frequencies can be tuned independently or modulated together via the Both CV input, which tracks 1V/oct.
Ceremony gets even more interesting when you start exploring the feedback and FM options. The Feed A and Feed B controls route the audio input back into their respective frequency controls, adding rich harmonic content even to simple waveforms. The FM Mod control lets Frequency B modulate Frequency A, and since this amount is voltage-controllable, you can easily create evolving timbral shifts on the fly. Patch a sine wave in and watch it transform into something far more complex.
At higher resonance settings, Ceremony goes into self-oscillation. If you ping the inputs with triggers or short envelopes, you'll get plucky, bell-like tones — the two frequencies essentially become your pitch controls. The voltage-controlled crossfader lets you blend or switch between two input sources, and lastly, a VCA CV in to control the dynamics of the output.
Verdict? A really interesting filter that doubles as a sound source with plenty of sweet spots to discover :)
