About the Overlay function
Overlay is a function that enables you to add or “overlay” a temporary offset (+/-) value to fader levels or Mix/
Matrix send levels in a current mix. The “overlaid” value is something like a transparent filter applied to the
level values. It enables you to temporarily adjust the relative levels without modifying existing scene data.

For example, assume that a regular musician for a show has been replaced by a new musician just before a
take, and that the audio level on the channel for the new musician is lower than the original musician by 6dB.
One way to correct this situation is to raise the head amp gain by 6dB. However, you should avoid this action.
If you leave the gain raised after the take, there might be a risk of overloading the head amp when the
original musician returns to the show. Another way is to simply raise the channel fader level. But, if the scene
is recalled later, the fader will return to the original level. You might then think of enabling Recall Safe to this
particular channel to avoid the level change caused by a scene recall. However, if you use Recall Safe, you
will be unable to utilize the detailed fader level settings that have been painstakingly programmed for every
scene.
This is where the Overlay function becomes very handy. Set an offset value of +6dB for the channel in
question. In this way, +6dB will be temporarily added to the existing current mix, and applied to the DSP
process. This Overlay filter (a set of offset values) is inserted between the current mix and the DSP process.
Therefore, as long as Overlay is enabled, a relative value of +6dB (in this example) will always be added —
even after the current mix is changed (e.g., by scene recall, etc.).
To troubleshoot these types of level issues, the RIVAGE PM series now features the Overlay function, in
addition to the conventional Global Paste function. The Global Paste function enables you to paste and write
a new value onto scene data, which is useful as a “permanent” editing function during programming.
However, this function is not appropriate when you want to resolve an issue temporarily but you still want to
return to the original value later. On the other hand, the Overlay function does not affect scene data directly.
Once you disable the function, the value will revert to its original setting. Therefore, this function is useful in
resolving real-time, temporary issues.
