Combining a traditional bucket brigade delay with high performance computation allows realtime convolution under CV control. Entirely digital in its implementation the delay lacks any of the artefacts commonly associated with bucket brigade devices and includes an asynchronous sample rate convertor output for sharp low pass filtering. The convolution allows instrument or room resonances from impulse responses to be applied to any signal, or production of arbitrary filter types.
