The Intellijel Quadra Expander adds voltage control over the Quadra’s Attack and Decay parameters, four EOC pulse outs corresponding with each of the Quadra’s four channels, and Analog OR logic outs normaled to each envelope pair. The module connects to the Quadra via four ribbon cables and features a jumper on the PCB that lets users select between two distinct looping responses.
4 x EOC (end of cycle) pulse outputs corresponding to the 4 function generators
Voltage Control of Attack and Decay (with attenuators) of all four envelopes
2 x Analog OR (aka peak circuit) Logic Outputs that are normally to the the two pairs of envelopes (1+2 and 3+4) with attenuators
Special quadrature modes for envelopes 1+2 and 3+4 with a jumper on the PCB to select two different kinds of looping responses
