Cytomic has updated The Drop to version 1.5.7
The Drop is an analog modeled resonant filter plug-in based on classic analog synth filters, as well as completely new designs. It uses the same high quality algorithms used in circuit simulators, but optimised to run fast, and features a gorgeous fully scalable user interface. There is a huge level of detail in the models, which gives them amazing drive and tone. The original structure of the circuits is preserved in the model, as is the location and shape of all major non-linearities.
