    This used to mean grabbing a calculator, dividing 60 by the tempo (beats per minute), then dividing that answer by the desired sub- beats . . . Sound like a hassle? Yeah, we thought so too. So the RP-20 Valve takes care of all the calculations for you! All you have to do is tap the TapIt (assign the tapit parameter to a footswitch) and manually tap in the desired delay time and the new time is added.

    Equalizers The RP-20 Valve has a broad selection of equalizer Modules to cover virtually any need. If you need bigger Guitar tone, the EQs will give it to you. Both mono and stereo modules are available. Remember that mono equalizers connected to stereo sources will always sum the stereo signal together for equalization (thus eliminating the stereo image).

    Parametric EQs offer the added flexibility of letting you define the center frequency you want to adjust, and how many frequencies around that center frequency you want to affect. Some of the PEQ modules in the RP-20 Valve, also include high shelf and low shelf EQ bands. A high shelf allows you select a frequency, and the boost/cut parameter changes the level of all the frequencies above that selected frequency.
