The button bar is used to switch the main display and parameter bar between envelope and EQ views. It also includes buttons that reset the envelopes and EQ or reverse the impulse response.

Button bar parameters
Reset button: Reset the currently displayed envelope or EQ to default values.
All button: Reset all envelopes and the EQ to default values.
Volume Env button: Display the volume envelope in the foreground of the main display. The other envelope curves are shown as transparencies in the background. See Space Designer volume envelope.
Filter Env button: Display the filter envelope in the foreground of the main display. The other envelope curves are shown as transparencies in the background. See Space Designer filter parameters.
Density Env button: Display the density envelope in the foreground of the main display. The other envelope curves are shown as transparencies in the background. See Use impulse responses.
EQ button: Display the four-band parametric EQ in the main display. See Use Space Designer EQ parameters.
Reverse button: Reverse the impulse response and envelopes. When the impulse response is reversed, you are effectively using the tail rather than the front end of the sample. You may need to change the Pre-Dly and other parameter values when reversing.
