Dual stereo delay
The dual stereo delay effect is a simpler, more concise, version of the current delay
device with the advantage of having two units in one effect device rack space. The dual
stereo delay is a dual stereo in and dual stereo out device with metering for each
discrete input and output.
BPM display mode:
• Tempo is accurate to 0.1 bpm.
• With global tap enabled the display shows global tempo regardless of delay time
setting.
• With global tap disabled the display shows the equivalent tempo assuming a delay of
one beat. For example, if the delay time is 500ms the tempo is calculated as 60/0.5
= 120 bpm.
• Up/down buttons adjust local or global tap tempo by 0.1 bpm.
Millisecond display mode:
• With global tap enabled the display shows current delay (in milliseconds) based on
global tempo and selected musical interval. For example, if a 1/8 dot interval is
selected on the delay control and the global tempo is 120 bpm the delay value
shown will be 0.75 x 60/120 bpm = 375 ms.
• With global tap disabled the display shows the actual delay time set on the unit.
• Up/down buttons adjust delay units by 1 millisecond increments.
If the global tap option is enabled the delay time rotaries will change from seconds
(milliseconds) to musical note durations as they do with the current effects units.
However, the seven-segment LED display will continue to follow the display mode
selected. Also, if the global tap option is enabled the tap button on the unit will not
affect the global tempo and should be greyed out.
