Isomer is an ensemble delay plugin for KORG prologue, minilogue xd and NTS-1. It has two main stereo delays offering tempo-synchronized time adjustment and near-infinite feedback. Their outputs are sent into four additional delays (two per channel) with their own individual feedback lines and with their times being modulated by four separate LFO signals. Thanks to the mutual phase offsets between these LFOs, and subtle feedback, the delay tail gets a smooth and highly musical detuning effect similar to chorus ensemble. Due to the opposing modulation between the left and right channels, Isomer also adds an extra dimension within the stereo field.
