==Reverb: firmware history==
 
* Firmware 7.00: "Improved Reverb block. The Reverb block has two new parameters: LF TIME and LF XOVER. LF TIME controls the decay time relative to mid-band. LF XOVER controls the crossover frequency to the low-frequency decay. Many real rooms have a longer low-frequency decay time relative to mid-band. These controls allow more natural reverb simulations. The Types in the Reverb block have been reworked due to the new algorithms."
 
* Firmware 10.00 introduced the "Stone Quarry" reverb type.
 
* Firmware 10.10: "Improved Reverb algorithm. This new algorithm has a smoother tail response and a more natural sound. A new reverb type, “Studio”, has been added which models classic digital studio reverb units. Increased maximum modulation depth of Reverb block. This results in more intense modulation effects at high Depth settings." Cliff: "Studio type is a different algorithm. The algorithms are similar but the Studio type is meant to reproduce that classic synthetic reverb sound in units like Lexicon and Eventide.."

Reverb spillover

Global reverb control

  • The Rev Mix parameter in the Global menu lets you boost or cut the Reverb Mix level across all presets at once.

Simulating room ambience

  • The Cab block has dedicated controls for adding room ambience to the sound.

Maintaining unity gain when using reverb

  • When using Mix to control the volume level of the Reverb, the volume level of the dry signal is affected also. In other words, when increasing Reverb with Mix, the dry signal's level decreases. To deal with this: turn up Mix to 50% and set Level to +6dB and use Input Gain to set the desired amount of Reverb. Or put the Reverb in a parallel row, see Effect blocks: series/parallel.

Position of the Reverb block

  • Cliff: "If there isn't distortion or modulation in the delay/reverb then the order is irrelevant since they are then Linear Time Invariant (or shift invariant in digital parlance). If there is a small amount of distortion or modulation then the order is probably still irrelevant. If there is a lot of distortion or modulation then the order may make a difference. However, typically the biggest difference, as noted above, is series vs. parallel since h1(t)*h2(t) is not the same as h1(t)+h2(t). If LTI h1*h2 = h2*h1. It may seem counter-intuitive that the order doesn't matter but try it and you'll be surprised." Source
