The 251e sequencer's per-stage loop counters enable nested rhythmic repetition without cycling the entire sequence

Each stage of the 251e Quad Sequential Voltage Source can carry a loop counter: a numeric value (1-9) that causes the sequence to jump back to the most recent begin marker and repeat that loop a set number of times before proceeding. When a stage is both a begin point and a loop number, nested loops are possible. Setting a loop counter to A (always) creates an infinite loop requiring a start pulse to escape. If a begin point itself has a number, the entire sub-loop repeats that number of times. In reverse mode, the roles of begin and loop stages swap. This enables long, non-repeating rhythmic structures within a compact 99-stage sequencer.

Examples

Mark stage 1 as a begin, set stage 4 to loop 3 times: stages 1-4 repeat three times before stage 5 plays. Nest another loop inside to create irregular phrase lengths without external sequencer logic.

Assessment

Describe the sequence order when stage 2 is marked begin, stage 5 is marked loop 2, and stage 10 is the end. How does enabling the always loop counter affect performance recovery?
