Fuji – Hexa Core Slope GeneratorIn the vast landscape of envelope generators, creating something truly useful yet timeless is no small feat. Fuji doesn’t aim to reinvent the envelope — instead, it delivers six channels of the most fundamental and musical analog AD circuits, refined for immediacy, flexibility, and performance. Each slope is tuned with a logarithmic attack and exponential decay, a configuration chosen to follow the natural response of human hearing. This ensures smooth, organic dynamics whether you’re shaping amplitude, filter movement, or modulation depth. Attack and decay times are perfectly balanced, both ranging from 1.5ms to 1.5s, making Fuji equally adept at snappy percussive envelopes and slow, evolving contours. Fully analog design keeps it warm and responsive, while selectable Hold and LFO modes on each channel extend its creative range far beyond standard AD envelopes. Gate input chaining allows easy grouping of synced envelopes with just a few cables, opening up complex rhythmic and layered modulation possibilities without clutter.
