Frequently Asked Questions

The reset input triggers a complete sequence restart; it accepts voltages between -8V and +8V, just like the other inputs.
The A-151 itself doesn't have built-in clock division; you’ll need external modules or patching to modulate the step rate independently.
While it excels at rhythms, its four-step limit means complex melodies require creative patching and potentially multiple instances; it's best for simple, repetitive patterns.
