KorgIsomer

Isomer is an ensemble delay plugin built for KORG prologue, minilogue xd, and NTS-1 hardware. At its core are two stereo delays with tempo-synced timing and near-infinite feedback. Their outputs feed four additional delays—two per channel—each with independent feedback and time modulation from four separate LFOs. The phase offsets between these LFOs, combined with subtle feedback, create a smooth, musical detuning effect reminiscent of a chorus ensemble. Because the left and right channels are modulated in opposition, Isomer also widens the stereo field for an extra sense of dimension. It suits producers seeking lush, evolving delay textures for ambient, electronic, and experimental music. Part of the Sinevibes KorgFX Collection, it uses studio-grade DSP algorithms calibrated for KORG hardware, with parameter mappings chosen for a natural feel, lag filters for smooth adjustments, and optimization for stability and performance on each device.
