Vostok Instruments Fuji is a 6-channel AD envelope generator.
The concept of Fuji revolves around a large number of primary envelope generator circuits along with some design solutions.
Envelope slopes are tuned using logarithmic attack and exponential decay. This configuration has been used for many years as it corresponds to the nonlinearity of human hearing, keeping dynamic changes always pleasant and natural to our ears.
The attack and decay range is symmetric with minimum and maximum rise/fall times from 1.5 ms to 1.5 s.
The Gate inputs chain adds flexibility to patching. Groups of synchronized envelopes can be easily created using multiple cables.
