Certain BreakTweaker settings and presets can be CPU-intensive, and depending on the specifications of your system you may experience audio dropouts during playback.
Here are a few things to try to lower the CPU usage:
- Disable any Generator Distortion that may be present on a track
- Disable any Generator Filter that may be present on a track
- Shorten the decay time of any active envelopes on a track
- Increase the audio buffer size within your DAW or plug-in host
