Features based on fxrand() function:
-num_steps: Number of sequencer steps-> 64, 96 (rare) or 128 (rare).

-frequency_range: possible range of frequencies of sounds-> all=45-2500Hz, high-> 1000-2500Hz (rare) and low 45-150 Hz( rare)

-interval_time: time interval between sequencer steps-> 0.2 s, 0.3s (rare) or 0.4s(very rare).

-steps_enabled: percentage of steps enabled, so steps that will sound.
