The Northern Light Modular Model hDI Delayed Inveloper is an H series dual ADSR and AD envelope generator module with looping capabilities for Buchla 200 format.

The Northern Light Modular Model hDI Delayed Inveloper uses analogue envelopes powered by a digital brain and includes normal and inverted outputs for each envelope. The Delayed Inveloper also features a looping function for each envelope with start and end controls for manual starting and stopping the loop.

Env 2 adds 10 repetitions before the end of the trigger as well as an offset trigger delay of up to 6 seconds. The trigger delay can maintain the same timing or be randomised for every new cycle.

All CV outputs produce exponential curves with the blue producing “normal” curves and the purple ones producing inverted curves. The BOTH CV out delivers a Max/Min version. Red outputs produce the end triggers at a fixed 3ms length.

The H-Series is half the height of a 1U 200 Series module and requires an h bracket to be mounted in a 1U space. Two h modules can be mounted in a 1U space.
