A performance-oriented digital delay station with four independent resampling delay channels, each ranging from 0.5ms to 15 seconds, supporting lossless stacking, linking, sync, buffer freezing, reverse delay, and switchable analog/digital sweep behavior.1005

Capabilities 2

Looperlooper
Each channel can freeze its buffer (hold) and loop it indefinitely; loop length is determined at the moment of hold activation and can be modified afterward by time controls.1005
Quad Delayquad-delay
Four independent resampling delay channels, each 0.5ms to 15 seconds (60 seconds total when stacked), with analog and digital sweep behavior, lossless digital normalling between channels.1005

Parameters 36

NameTypeRangeBehavior
CH A Behaviour SwitchswitchSelects between analog (BBD/tape-like variable-rate resampling with pitch changes) and digital (granular crossfading with no pitch change) delay behavior; switchable per channel at any time.1005
CH A FBCK KnobknobControls feedback amount with a nonlinear response: starts sharply from 0%, rises quickly past 80%, devoting nearly half of the range to the final few percent, approaching 100%. A full turn equals a 10V CV change.1005
CH A Hold ButtonbuttonFreezes the buffer contents and loops them, ignoring the input; loop length equals the delay time at the moment of activation. Also used with shift to flip CV polarity between -1V/oct and +1V/oct.1005
