1. Reverb in Siren

2. What is Reverb? Reverberation is the persistence of sound in a particular space after the original sound is removed. A reverberation, or reverb, is created when a sound is produced in an enclosed space causing a large number of echoes to build up and then slowly decay as the sound is absorbed by the walls and air.sound echoes http://en.wikipedia.org/wiki/Reverberation

3. What is Reverb? In other words it’s a bit like an echo but don’t say that in an essay because its more than that! Its where a the sound is sampled and then played back along with the original with a slight delay

4. What is Reverb? You can change the delay and the “colour” of the reverb

6. How does it work in Siren – The Unit

7. How does it work in Siren – The master fader First White Fader Button A

8. How does it work in Siren – The control button It is marked Aux. Pressing this will mean reverb is activated for this fader

9. Setting the Reverb When power is first turned on, the MIDIVERB III automatically resets to the Program mode and the last program selected before the power was turned off will be currently selected. For the purpose of illustration, let's assume that you are turning your MIDIVERB III on for the first time. The MIDIVERB III's front panel should look like this: In the Program mode when initially powered up, note that the front panel will display the following: A) The PROGRAM LED will be lit, indicating that the MIDIVERB III is in the Program mode. B) The display will read the program number, in this case "000".

10. Setting the Reverb Programme There are three ways to select a program on the MIDIVERB III when it is in the Program mode; by using the VALUE buttons, by using the ten keys on the right of the front panel which function as a keypad in the Program mode, or by receiving a MIDI program change (when Program Change has been enabled). WITH VALUE BUTTONS If we desire to select program 023, for example, we could simply press and hold the "up" VALUE button until program 023 was displayed. At that point, the MIDIVERB III's front panel would look like this: Note that the front panel still displays the following: —The PROGRAM LED will be lit, indicating that the MIDIVERB III is in the Program mode. —The display will read the program number, only now it reads "023".

11. Setting the Reverb with the keypad Another way to select program 23 would be to use the ten function keys on the right of the front panel which double as a keypad in the Program mode (notice the numbers beside each button). To do this we would do the following: 1) Select the three digits (all programs must have 3 digits) from the keypad. In this case 0 (INT. PROG button), 2 (DELAY button), 3 (CHORUS button). The program will be selected after the third digit is entered. 2) The three digits must be selected within 4 seconds or the program will revert back to the previous program number.
