ARP
ARP is the arpeggiator: feed it notes and it turns them into a repeating musical pattern.
It has its own input/output bus handling and provides performance controls for pattern behaviour, sync and latch.
Accent
ARP can generate a repeating ACC pattern independently of the arpeggio order. Accent division can be OFF or every 2–16 steps, with an amount of 25%, 50%, 75% or 100%.
The accent phase resets with the pattern/reset state, so it remains rhythmically predictable — assuming you consider your patch predictable at this point.
The ACC output becomes particularly useful when routed through PROC and then into something like filter frequency.
Try this
ARP ACC → PROC (SLEW) → VCF FREQ
This turns hard accent jumps into a smoother rhythmic filter movement. See the complete Smooth an ARP Accent tutorial.
