How to Use This Calculator
  1. Enter BPM, Beat Division, and Quarter note.
  2. Set Eighth note, Sixteenth note, and Attack Time.
  3. Adjust Hold Percentage, Release Shape as needed.
  4. Review the Cycle Length (ms) result.
  5. Use Release Time (ms) and Hold Time (ms) to inform your decision.

Hold Percentage
Percentage of the cycle to hold maximum compression.
Release Shape
Select the release shape

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    BPM = 128, Beat Division = 1, Attack Time = 5, Hold Percentage = 30 = 5 input(s) provided
  2. Calculate Cycle Length
    Cycle Length = 0
    468.75 = 468.75
  3. Calculate Release Time
    Release Time = 0
    323.12 = 323.12
  4. Calculate Hold Time
    Hold Time = 0
    140.63 = 140.63
