先拿到去鼓伴奏并检查残留、速度和第一拍，再用 L1→L4 四层递进，从底鼓加反拍军鼓一路加到踩镲、原曲底鼓型和过门。 Get a drumless track, check residue, tempo, and beat one, then climb a four-layer ladder from kick and backbeat to hi-hats, the song’s real kick pattern, and fills.
用 G0→R6→L6→O6→G1 先在同音色守住 RLLRRL／LRRLLR 的六格间隔与首尾重音，再只移动 Pad 行，并以回到原基线证明配器没有改写击序。 Use G0→R6→L6→O6→G1 to preserve six-slot spacing and outer accents on one voice, mirror the lead, change only the pad row, and prove the sticking survives the return.

保留直拍副本，用 A–B–C 双音坐标测量八组真实起点；分开验证已写入位置的事件迁移与目标端参数重建，不把面板数字当通用配方。 Preserve a straight copy and measure eight A–B–C units; test committed-event transfer separately from a target-native recipe instead of treating panel numbers as universal.
固定同一鼓段、Threshold、Ratio 与检测路径，对比 U/F/S/R 四个版本；分开记录原始 Gain Reduction 与响度匹配后的听感，定位瞬态变钝、pumping 和恢复过慢。 Freeze one drum passage, threshold, ratio, and detector path; compare U/F/S/R while keeping raw gain-reduction evidence separate from level-matched listening.
用 C/O/R/F 四副本固定一小节事件，分别验证加法录制、替换边界、Undo 与定点擦除；依据幸存的 Kick、Snare、Hat 选择模式。 Use C/O/R/F copies of one fixed bar to test additive recording, replacement boundaries, Undo, and targeted erase; choose the mode from surviving kick, snare, and hat events.

先判断起音后是否有稳定尾音、它是否与真实 bass／和声冲突，再用同一条 MIDI 完成 A0 原音、两个候选与 A1 回归的四窗口盲序对照，最后用 Pad 现场复核手感。 First prove a stable tail and a real bass/harmony conflict, then send one MIDI passage through the original, two candidates, and an original return across four blinded windows before a live-pad playability check.
固定 Fill 节奏，先比较末击手指到第 1 拍锚点的两条匹配路径，再单独测试底鼓／Crash 同击；录到第 2 拍并分类第一个失败事件。 Freeze the fill, compare two matched last-hit-to-landing paths, then open a separate simultaneous-voice gate; capture through beat 2 and classify the first failure.
先按“以后要改演奏，还是要保住声音”选择主记录；用途未知时同一遍双录，再用改单击、换鼓组、停用原音源与新会话重放四项测试证明资料可恢复。 Choose the primary record by whether you must edit the performance or preserve the sound; when the future is unclear, capture both and prove recovery with four controlled tests.
把自动瞬态标记当候选，为每个 slice 记录起点、下一边界与尾音归属；逐片通过起音、尾音、爆音三门，再按原始顺序回拼 A/B。 Treat automatic transient markers as candidates, record each slice's start, next boundary, and decay owner, then pass attack, tail, and click gates before an original-order A/B rebuild.
用四小节标记样式先证明 Clock 速度，再核对 Start/Continue/Stop 走带与 SPP 位置；三层都通过后，才用双路录音调整稳定的同步延迟。 Use a four-bar marker pattern to prove Clock rate, then Start/Continue/Stop transport and SPP location; adjust a stable sync delay only after all three layers pass.
先用当前 FingerDrum 映射公式建立源格→目标格账本，按“行 + 目标格”标出 many-to-one，再核对最终保留的力度、缩放时值，以及为何切回后不能复原。 Use FingerDrum’s current mapping formula to build a source-to-target ledger, group many-to-one keys by row and target, then verify the surviving velocity, scaled length, and why switching back does not restore the lost hit.

保留一小节 A0 锚点，先做减法，再制作单变量与短段尾版本；用原创 8 小节练习表和第 9 小节落点测试，让变化服务段落而不是随机堆 fill。 Preserve an A0 anchor bar, subtract before adding, then build one-variable and short-ending copies; use an eight-bar worksheet and bar-9 landing test so each change serves the phrase.
逐垫记录数字音符编号、MIDI 通道与接收目标，用一张表区分输入路由、映射错位、意外叠层与未保存预设，再决定只改控制器还是音源。 Capture one hit per pad, compare numeric notes, channels, and receiver targets, then separate input routing, map mismatch, unintended layering, and unsaved presets before changing one side.
检查第 1、9、17、33 小节，初步区分首拍偏移、固定 BPM 误差、段落变速与分轨残留，再决定让 click 跟随原曲，还是制作固定网格练习副本。 Check bars 1, 9, 17, and 33 to test for downbeat offset, fixed-BPM error, section-level tempo movement, and stem residue—then decide which clock should follow the other.
