User Manual S P E C U L A R T E M P U S (Firmware V3.8) 2.1 mm Type‐B negative‐center USB Socket Mono Input Effects Loop ‐ 1/8” audio socket Use this if using only 1 input Chapter 1 ‐ OVERVIEW Specular Tempus is a compact yet powerful reverb and delay effect processor in a compact pedal. Featuring 36 algo‐ rithms (13 reverbs, 17 delays, and 6 reverb & delay combinations), 8 presets. Stereo in/out, tap‐tempo, and extensive inter‐connectivity. Using the SpecLab software (free download) users get access to an extended set of parameters for deep‐editing of the algorithms. Preset System Specular Tempus has 32 presets organized within 4 pages, where each page contains 4 banks, and each bank contains 2 patches (A and B). A | B A | B A | B A | B A | B A | B A | B A | B ...

User Manual S P E C U L A R T E M P U S (Firmware V3.8) 2.8 Tap Tempo In Specular Tempus tap‐tempo can be accomplished in 3 ways : 1. On the pedal itself, using footswitch B as tap‐tempo switch. 2. Using external aux switch box (see Chapter 4). 3. Using MIDI controller. With option #1, footswitch B becomes tap‐tempo switch and can no longer be used to call patch B. Therefore, under this scheme the available number of presets is 16 (1A through 16A). You can still save changes to patch 1B through 16B, but you won’t be able to call them. Local / Global tempo The tempo of the Delay algorithms in Specular Tempus can be set to be Local or Global. Local means the delay time is set to the tempo as was saved in the preset. Global means the delay time is set to a global tempo shared by other delay algorithms. For example, 2 different delay algorithms are stored in preset 1A and 1B, both are set to use global tempo. Then any tempo changes you make while using the delay in preset 1A will become a global tempo which will then dictate the tempo for the delay algorithm in preset 1B. The Local / Global setting can be specified on per‐preset basis. ...

There are 2 operation modes to choose from: 1‐Layer mode* : You can fade out the sustained sound, and immediately fade in a new one. N‐Layers mode** : You can add infinite number of layers of sustained sound, creating an ever‐dense ambience goodness. ...

User Manual S P E C U L A R T E M P U S (Firmware V3.8) Chapter 4 ‐ INTERCONNECTIVITY Specular Tempus has been designed with the need to interconnect with the outside world in mind. It sports no less then 4 interfaces : Aux‐In, Aux‐Out, MIDI In, and Effects Loop. We will now explain what these interfaces do. 4.1 Aux‐In The Aux‐In jack can be connected to any external switch box equipped with single, dual, or triple buttons / switches. Use the SpecLab software (Global Configuration menu) to customize what each switch should do, from basic ones such as Bank Up, Bank Down, or Tap Tempo, to the more exotic ones such as Warp functions, Favorite preset call, and Momentary functions. We will now describe in details the functions to which the switches can be assigned. External switch box (3‐buttons) Wiring : Tip, Ring, Tip + Ring stereo (TRS) cable ...
