The Intellijel Quadra features 4 function generators for CV modulation in eurorack synthesizers
1. ad (attack – decay)
2. ahr (attack – hold – release)
3. cycle (ad envelope loops)
each function can have linear or exponential curves.
wide time range for attack/decay controls: <0.5ms to well over 30s
All analog and discrete logic for function generation (totally smooth and continous waveforms)
