Struct ArpPattern 

pub struct ArpPattern { /* private fields */ }

Sixteen pattern steps, two bits each — the Stage 4 arpeggiator’s accent, gate and pan rows.

The panel edits these as a grid: the manual’s Pattern Edit page moves a cursor with a Position dial and sets the step under it, and the Pattern Pan page moves a step “between Left, Center and Right”. Three values per step is exactly two bits, and a pattern runs to sixteen steps, which is exactly the 32-bit slot.

⚠️ Step order is inferred, not established. Read low-bits-first the corpus values fall out as music — 0x01010101 is an accent every fourth step, 0x55aa5500 is four left then four right then four left — but correlating the highest non-zero step against the sibling arp_pattern_length fails in both directions, so either the word keeps all sixteen steps regardless of the active length or that field is not a step count. Inferred from specimens; not confirmed on hardware.

The slot is wider than crate::fields::ENUMERABLE_BITS, so --set spells it by its stored bits — 0x55aa5500 is the readable form for a pattern anyway.

Implementations

impl ArpPattern

pub const STEPS: usize = 16

Steps a pattern can hold.

pub fn raw(&self) -> u32

The stored word.

pub fn steps(&self) -> [u8; 16]

The sixteen steps, 0..=3 each, lowest bits first.

pub fn is_empty(&self) -> bool

Whether every step is zero — an unset row.

Trait Implementations

impl Clone for ArpPattern

fn clone(&self) -> ArpPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ArpPattern

impl Debug for ArpPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

The stored word in hex, which is what --set takes back.

impl Default for ArpPattern

fn default() -> ArpPattern

Returns the “default value” for a type.

impl Display for ArpPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

The steps as a row: 1010 1010 .... — a dot for a zero step.

impl Eq for ArpPattern

impl Hash for ArpPattern

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Packed for ArpPattern

const MAX_BITS: u32 = 32

Bits the widest value of this type occupies. Used to check statically that it fits its slot.

const DECODE_BITS: u32 = u32::BITS

Widest slot this type can decode without losing bits on re-encoding.

const CONTROL: ControlKind

Which panel control this value is, for a caller building an interface over the field registry.

type Error = !

Why a bit pattern is not a valid value. Infallible when every pattern is.

fn from_bits(bits: u64) -> Result<Self, Self::Error>

Decode from the field’s bits, already shifted down to bit 0 and masked.

fn to_bits(&self) -> u64

Encode to the field’s bits, in the same shifted-down form.
