WritePatternPhase

WritePatternPhase は, 強度が全振動子・全 Pattern で共通の場合に使える WritePatternBuffer の軽量版.

API

Rust

WritePatternPhase {
    bank,
    start_index,
    depth,
    intensity,
    patterns,
};

Python

WritePatternPhase(
    bank=bank,
    start_index=start_index,
    depth=depth,
    intensity=intensity,
    patterns=patterns,
)

C#

new WritePatternPhase(
    bank: bank,
    startIndex: startIndex,
    depth: depth,
    intensity: intensity,
    patterns: patterns
);

フィールド	型	説明
bank	PatternBank	書き込み先バンク
start_index	usize	バンク内の書き込み開始インデックス
depth	PhaseDepth	位相のビット幅 (下記参照)
intensity	Intensity	全振動子・全 Pattern に共通の強度
patterns	&[Vec<Vec<Phase>>]	書き込む位相の列 (1 個以上 depth.max_count() 個以下)

PhaseDepth

バリアント	1 フレームあたりの Pattern 数 (max_count())	説明
Bits8	5	位相を全分解能 (8 bit) で送る (デフォルト)
Bits4	11	位相を上位 4 bit に量子化して送る

Example

Bits4 で 4 枚の Pattern を 1 コマンドで書き込み, ConfigPattern + ActivatePatternBank で STM として再生する例.
