EQ Plug-Ins : EQ III : Adjusting EQ III Controls : Using EQ III in Band-Pass Mode

Using EQ III in Band-Pass Mode
You can temporarily set any EQ III control to Band-Pass monitoring mode. Band-Pass mode cuts monitoring frequencies above and below the Frequency setting, leaving a narrow band of mid-range frequencies. It is especially useful for adjusting limited bandwidth in order to solo and fine-tune each individual filter before reverting the control to notch filter or peaking filter type operations.

To switch an EQ III control to Band-Pass mode:
*
Hold Control+Shift (Mac) or Start+Shift (Windows), and drag any rotary control or control point horizontally or vertically.
