Then to detect each beat you can make an envelope detector circuit with a resistor and rectifier charging a capacitor. The capacitor and its charge and discharge resistors values detrmine how much filtering of the cycles occurs. Its output can be squared with an opamp or Cmos Schmitt-trigger and used to clock a 4017 stepper.
