With Cascade, Qu-Bit Electronix introduces a very flexible attack/decay envelope with variable curve characteristics. The density of functions in this module is impressive: the internal ratcheting generator creates a firework of further triggers for the envelope with every incoming gate. In addition, the transient generator can be set to loop mode and the freeze function can be used to hold the current voltage manually or via gate.
In combination with a sequencer and a BPM-synchronized LFO, Cascade is a real workhorse for modulations!
