F_GENSEQ by Request For Music is not a traditional step sequencer, but rather a probability-driven musical system for Voltage Modular built around persistent musical material and live interpretation.
This demonstration video features three Genseqs to serve as 2 melodic and one bass sequence background for some lead doodling. Also a role for another upcoming module F_CLOXZ that drives them.
"F_GENSEQ is a compact generative sequencer built around probability, repetition, and controlled randomness. Instead of programming fixed step values, F_GENSEQ generates evolving musical patterns from an internal pool of notes, using probabilistic rules that shape when notes play, repeat, or remain silent. The module is designed for generative melodies, evolving basslines, ambient sequences, and rhythmic pitch modulation. In WINDOW mode, variation is stable within a cycle and only changes when explicitly regenerated or when the window position shifts. In PURE mode, the pitch is freshly randomized on every clock tick.
At the core of F_GENSEQ lies a fixed internal 64-step pitch pool. This pool defines the musical material of the sequence and is interpreted by the controls, rather than being continuously regenerated. Once created, this internal sequence remains unchanged until a RESET operation is performed. This makes sequences persistent, repeatable, and suitable for composition and patch-based workflows."
