The A-143-2 is a quad ADSR envelope generator comprised of four entirely independent ADSR envelopes. Each envelope section features a gate and re-trigger input, a time range switch, and a single output. There are also several outputs that send gate signals when specific time stages have been completed, allowing users to efficiently create complex sequences and ersatz LFOs.
