The manual covers:
- what the series is for: how beating comes about, why its oscillators and filters are tuned in hertz, and the slow changes that move a drone at several speeds at once;
- a chapter for each module, with a labelled view of its panel and every control and jack;
- Littoral’s sine and its harmonics, its BEAT law, its drift from cold and its mains hum;
- Fluvial’s responses, its resonance up to and past self-oscillation, and PING;
- Calderal’s sideband rejection, frequency shifting and feedback ladders;
- Alluvial’s wear pass by pass, its erase head, wow and flutter, and damage;
- Glacial’s curve shapes, its drum’s rate and inertia, and PHASE;
- seven drone patches, each drawn as the modules’ panels with their cables.
