is adjusted to zero. In this case, the signal from the LFO module will simply be delayed.

4.7 The Envelope Module

Each row of the Ultra Analog is equipped with two enve-

lope generators, the Filter Env and Amp Env modules which

are used to modulate the Filter and Amp modules. Both en-

velope generators have the same user interface and offer the

same functions. Envelopes are generated through the use of a

standard ADSR (attack, decay, sustain, release) approach in-

cluding velocity modulation and looping capabilities.
