從 generator 把 voicing 或整段和弦進行接過來，逐一聲部用麥克風唱錄，最後疊成你的 harmonizer。 單和弦模式：voicing 拆成最多 3 個聲部（bass / middle / melody），逐顆音錄。 進行模式：每條 lane = 一個聲部唱完整段進行，配 backing piano 伴奏，可拖動 waveform 對齊。Pull a single voicing or a whole progression from the generator, record each voice with your mic, stack into your own harmonized take. Single-chord mode: the voicing is split into up to 3 parts (bass / middle / melody) — record one note at a time. Progression mode: each lane = one voice singing the whole progression over a backing piano; drag the waveform to align.
