SH-201

Synthesizer

Q.The SH-201 has an "FILTER ENV" section on the right side of the front panel that's equipped with A, D, S, and R sliders. What can I control with the FILTER ENV section?

A.The SH-201's FILTER ENV section allows you to control the way the tonality of the sound changes over time.




On instruments such as piano, each note begins with a bright tone, and gradually darkens (becomes more mellow) as the note decays.

The filter envelope lets you create and control time-varying tonal changes of this type.



  • A (attack time) slider
    Specifies the amount of time between when you press the key and the cutoff frequency reaches its highest (or lowest) point. Moving the slider upward lengthens the time, and moving it downward shortens the time.
  • D (decay time) slider
    Specifies the amount of time between when the cutoff frequency reaches its highest (or lowest) point and when it falls to the sustain level. Moving the slider upward lengthens the time, and moving it downward shortens the time.
  • S (sustain level) slider
    Specifies the cutoff frequency that is to be maintained (after the attack time and decay time has elapsed) until you release the key. Moving the slider upward raises the cutoff frequency if DEPTH is set to a positive (+) value, or lowers it if DEPTH is set to a negative (-) value).
  • R (release time) slider
    Specifies the amount of time between when you release the key and the cutoff frequency falls to its minimum level. Moving the slider upward lengthens the time, and moving it downward shortens the time.
  • DEPTH slider
    Specifies the direction and amount in which the cutoff frequency will change. The DEPTH slider can be set to positive (+) or negative (-) values. At the center position (0), no change will occur.
    • Moving the slider upward (in the "+" direction) causes the cutoff frequency to change in an upward direction. The higher you move the slider upward, the more the cutoff frequency will rise.
    • Moving the slider downward (in the "-" direction) causes the cutoff frequency to change in a downward direction. The lower you move the slider downward, the more the cutoff frequency will fall.
