The MiniMod Multi Burst Envelopes module generates variable length bursts of repeating envelopes that can change over time, with CV control of all functions.

AJH Synth's Multi Burst Envelopes is a unique burst generator that adds an envelope to each impulse, resulting in shapeable modulation. In collaboration with Tom Wiltshire, this module is a first of its kind that can generate complex envelope burst sequences that would otherwise require a slew of individual modules and complex patching. At its core is a selectable 1–40 burst sequence, which can be shaped in one eight ways: sine, log down, log up, expo down, ramp up, triangle, ramp down and pulse. 

The envelope shape of a burst is chosen with the rotary switch, or it can be varied using an external CV, so that it is even possible to choose a different envelope shape for each individual burst in a sequence.  The width of the envelope (i.e. the attack and decay time) is varied with the P-WIDTH control and this can also be CV controlled as a sequence is progressing, so it is possible to vary the envelope speed of each individual envelope burst while a Burst Sequence is running.

Use the internal clock or patch an external source to give you complete control over the rate of your burst. A trigger input functions in two modes: One shot, which plays an entire sequence when it sees a trigger, ignoring any other triggers until it completes; and a Retrigger mode that will restart the sequence every time a new trigger is present. An auxiliary Gate output is available, should even more complex modulation be desired. Finally, a CLK input and companion button lets you increment the sequence by one on each impulse or button press.

The repeat time of individual bursts in a Burst Sequence is set with the LFO Rate control. The LFO rate can be varied with an external CV as a sequence is progressing, so the gap between envelopes can speed up or slow down over time. An external clock can also time the bursts in a burst sequence instead of, or in addition to the internal LFO. Bursts can also be manually incremented with the CLK push button.

The SLOPE control allows Bursts to start quietly and build in level to maximum, or they can start at full level and then reduce in level as the Burst Sequence progresses. In the centre position all Bursts are of equal level.
