Cèis is a classic ADSR envelope generator with some extra features packed in. Four faders control the A. D. S. and R. segments.Each of these can be CV controlled. Control voltages sum with the fader position both extending the range of the timed segments and offering external modulation capabilities over the envelopes timing. There is a gate output per segment.These are high for the duration of the segment as it is active.In addition, there is a combined trigger output which fires at the beginning of each envelope segment.This allows for the module to behave as a trigger burst generator with CV controllable durations between pulses. The envelope output can be shaped from linear forms to exponential.A button allows for manual control in addition to a gate/trigger input jack. The toggle sets the module's behaviour to work with gates or triggers.When in the TRIG position, the envelope's attack segment will be forces to complete regardless of the pulse duration.This allows for the Attack and Release controls to be used as a single shot controlled AR/AD envelope. The design is all analogue and responds immediately to external control. Show more
