Quadlopes

The quadlopes is four simple attack & release envelopes. Each envelope can be gated individually and/or simultaneously with the master gate input.

Envelopes will begin the attack phase as soon as there’s a gate present. If the gate outlives the length of the attack then the envelope will “plateau” or enter a sort of sustain stage. When a gate is no longer present then the envelope starts it’s release/decay phase.

Envelopes can be re-gated. If an envelope is halfway through a release and then a gate is re-applied, the attack phase will begin again from wherever release left off. The master gate will re-gate any of the individual envelopes as well.

DIY note: use female pin headers + the male pin headers to connect the PCBs together. It will be a huge pain the ass if you have to desolder the boards to troubleshoot.
