When you load a sample, the Force will automatically search for any tempo information stored in the file’s metadata. If no tempo is recorded to the file, the Force will analyze the tempo manually based on a selected range in the preferences and assign a tempo on its own. Once a tempo is assigned, the file will be “warped” (stretched or condensed) to the project tempo with the assigned tempo as the starting point.

If you find that your files are not syncing with your project after “warping” them, it’s very likely that the file was assigned the wrong tempo from the start. There are a few reasons this could happen:

  1. The selected tempo range in the Force preferences is not appropriate for the genre/style of music.
  2. The file does not have a consistent tempo, or the tempo varies
  3. The file has blank space at the beginning or end that will affect it’s size when warped

Re-Analyzing and Adjusting Sample/Loop BPM

Here are a few steps you can take to resolve this. Keep in mind that you’ll want to know the actual tempo of the file before determining that it is being analyzed incorrectly.

Adjust the BPM Detection Range

Try adjusting the BPM Detection Range in the Force Preferences. You’ll find the range under the General tab. This may be especially helpful if you find the assigned tempo is close to double or half of the intended tempo.

  1. Press the Menu button and then press the gear icon at the top of the screen to enter the preferences menu.
  2. Find and select the General tab and find the BPM Detection Range. Choose a more applicable range from the list. For example, if an 80 BPM loop is analyzed at 160, choose the range 58 to 115 BPM to eliminate the possibility that the sample will be analyzed at double it's original speed.
  3. To re-analyze your sample/loop, press the Clip button.
  4. Choose Region at the top-left of the screen and, if necessary, press Browse Samples to choose the sample you'd like to reanalyze.
  5. Make sure Warp is turned off and press Detect. Here you can set the BPM in one of three ways:
    1. Press Detect to have Force analyze the BPM for you according to the new BPM Detection Range.
    2. Play the clip and use the Tap Tempo button to input the BPM.
    3. Enter the BPM manually. Use the scroll knob or SHIFT + the scroll knob to manually adjust the tempo if necessary.
  6. Once you can confirm the new tempo is correct, turn Warp back on and the file should snap more closely with the intended tempo.

Nudging or Shifting Tempo

If the assigned tempo is only slightly off from the intended tempo, that could be because of a unique or varying rhythm. In this case, it may be better to simply nudge the assigned BPM closer to it's intended value to improve the timing with the project.

  1. Press the Clip button to enter the clip view, and press Region at the top-left. If necessary, press Browse Samples to choose your sample for editing.
  2. With Warp turned ON, press the BPM and use the scroll knob to manually nudge the BPM while watching the clip region shift across the grid. You can hold SHIFT while using the scroll knob to shift in smaller increments.
