How to change the BPM of an audio clip

如何更改音频片段的 BPM

BPM is a metadata field on each clip in the Music Group (MG) panel. You edit it there, then load the clip into the audio layer (L4) of the Scheduler (AC).

BPM 是音乐组(MG)面板中每个片段的元数据字段。在那里修改,再把片段载入调度器(AC)的音频层(L4)。

How to do it in 3SAX V3

在 3SAX V3 中的操作步骤

1. Open the Music Group (MG) panel.

1. 打开音乐组(MG)面板。

2. Select the audio clip with the Clip ID you want to change.

2. 选中要修改的片段(按 Clip ID)。

3. Edit the BPM field and confirm the duration stays correct.

3. 修改 BPM 字段,确认时长仍正确。

4. Check the real-time hint beside the field (green = valid, red = error with a fix example).

4. 查看字段旁的实时提示(绿色=有效,红色=错误并给出修正示例)。

5. Load the clip into L4 of the Scheduler (AC) timeline.

5. 将片段载入调度器(AC)时间线的 L4。

6. Adjust AC+MUS event pairs if tempo-derived timing shifted.

6. 如节奏相关时序变化,调整 AC+MUS 事件对。

7. Run whole-project validation and fix any listed errors before RENDER.

7. 渲染前运行整项目校验,修正列表中的错误。

What you CAN and CANNOT do

能做与不能做

Can:

能做:

  • Edit Clip ID, Duration, BPM as clip metadata.
  • Reuse a clip from the Library (LIBRARY) and set its BPM after loading.
  • Re-time scheduler events to match the new BPM.
  • 编辑 Clip ID、时长、BPM 等片段元数据。
  • 从资源库(LIBRARY)载入片段后再设 BPM。
  • 按新 BPM 重新调整调度事件时序。

Cannot:

不能做:

  • Stretch or re-render the audio file itself; BPM is metadata, not audio processing.
  • Compose or generate music in the tool.
  • 拉伸或重新渲染音频文件本身;BPM 是元数据,不是音频处理。
  • 在工具内作曲或生成音乐。

If you miss a required field, the hint turns red and the render can fail. Invalid codes are rejected at validation.

必填字段缺失时提示变红,渲染可能失败。无效代码会在校验时被拒绝。
