Chapter 2: Your First Session with the QuadraVerb 2. A basic introduction to getting the unit up and running, auditioning the factory Programs, adjusting levels, comparing and storing edited Programs. Chapter 3: Overview. A detailed look at the signal processing capabilities of the QuadraVerb 2, and the concepts of multi-effect programming. Chapter 4: Making Your Own Patches. A guided tour for programming typical single and multi-effect applications. Chapter 5: Description of Controls. A "dictionary" of all parameters, buttons and connectors, including Global mode parameters. Chapter 6: Advanced Applications. Advanced uses of the QuadraVerb 2, such as MIDI functions, footswitches and using "tap tempo" to control delay times. Chapter 7: Alesis Optical Interface. How the QuadraVerb 2 fits into an ADATcompatible studio. Chapter 8: Trouble-Shooting. Contains the Trouble-shooting Index, maintenance and service information, and MIDI implementation chart. Conventions The buttons, knobs, and rear panel connectors are referred to in this manual just as their names appear on the QuadraVerb 2, using all capital letters and in brackets (Examples: [PROGRAM] button, [< BLOCK] button, [VALUE/ENTER] knob/button, [DIGITAL IN] connector, etc.). J When something important appears in the manual, an icon (like the one on the left) will appear in the left margin.
