The 250e function generator's five stage modes — pulse, advance, sustain, enable, stop — allow each step to behave differently in response to gates and time
The 250e 16-stage function generator provides five per-stage advancement modes. Pulse mode (default): advances on a pulse or switch press. Advance mode: advances only when the stage timer expires. Sustain mode: runs on timer but pauses if a gate is held high at the Start/Adv input. Enable mode (opposite of sustain): pauses until a gate is high. Stop mode: halts at the stage until manually triggered. These modes enable complex gate-controlled sequence behaviors — steps that hold until a performer makes a gesture, steps that skip unless triggered externally, and steps that run freely on internal time. Any combination across 16 stages creates highly configurable sequence structures.
Examples
Set stage 8 to Stop to create a performance cue point where the sequence always pauses, waiting for a drum hit pulse to advance; set stages 9-12 to Enable to play only when a sustained gate is present.
Assessment
Describe the complete behavior of a sequence where stages 1-4 are in Advance mode (1-second each), stage 5 is in Stop mode, and stage 6 is in Enable mode with a 2-second timer. What triggers are needed to progress through all stages?
