Sound Programming

Reverb

The Reverb effect allows you to add a bit of reverb (not echo!) and presence to Tsunami’s sound effects. Be forewarned - unless you are a trained audio technician, adjusting the reverb effects can easily result in some strange or unpleasant results. We recommend you take your time and experiment cautiously.

There are eight CVs associated with the Reverb module:

CV 161, Reverb Control Register CV 162, Reverb Output Level CV 163, Reverb Delay Time CV 164, Reverb Feedback Level CV 169, Mixer Ch 0 Reverb Send Level CV 170, Mixer Ch 1 Reverb Send Level CV 171, Mixer Ch 2 Reverb Send Level CV 172, Mixer Ch 3 Reverb Send Level

Description

Reverb Control Register CV 161 is the Reverb Control Register which allows you to select one of several Reverb Presets or to choose the User Adjustable Reverb.

The presets contain predetermined values for the Reverb Output Level, Reverb Delay, Reverb Feedback Gain level, and Reverb Send Levels. Table J lists the available presets and the corresponding value for CV 161.

User Adjustable Reverb The Reverb works by simulating the effect created when a sound wave is heard along with a delayed version of the sound that has been reflected off of some other hard surface. Tsunami’s reverb is designed to produce a reverb effect due to early sound reflections off a nearby surface such as a rock cut or a canyon wall.

The User Adjustable Reverb provides three controls plus an input mixer (described in the next section). The Reverb Controls are as follows:

CV 162, Reverb Output Level This CV determines the amount of reverb signal that is mixed back with the original audio signal. CV 162 may be set to any value between 0 (minimum) and 255 (maximum).
