Why it sounds like this
- Tempo
- Your 130 bpm reading is entrained directly to the beat, giving 130 BPM.
- Energy
- You are at 72% of your 181 bpm max, so drive sits at 56%. Push harder and the mix adds layers; ease off and it thins out within a few seconds.
- Texture
- That effort lands in the “Float” band: half-time, wide reverb, band-pass, long tail, G mixolydian. Each band swaps instrumentation rather than just turning the volume up.
- Structure
- Your 30 minute session sets 4 music blocks — one drop per 8-minute block.
