OVUM for Eurorack is a powerful, all-analog drone and modulation source designed for exploratory sound design across ambient, drone, and noise-focused systems. Adapted from the standalone OVUM synth, this Eurorack version delivers a dense bank of five triangle-core oscillators, each individually controllable and routable. Capable of everything from dissonant drone clusters to evolving chordal textures and slow-moving modulation, OVUM excels as both a sound source and a utility for complex patching. Each oscillator can be shaped via a crossfade between triangle and square waves, and switched independently between audio-rate and LFO operation, allowing for deep interaction within a patch. With four individual outputs normalled to a main mix output, OVUM integrates easily into both compact and expanded systems. The one-control-per-function layout keeps things immediate and tactile, encouraging hands-on exploration.
