THE ECHO555
The Mode section
The Mode section acts as a signal gate with three different ways of passing the input signal on to the subsequent
main sections.
Mode
This switch has three positions:
•Normal
The standard send/insert effect behavior where the input signal is fed continuously into the device.
•Triggered
This mode keeps the signal unprocessed until you hit the Trig button. This mode is for situations where you only
want the echo effect momentarily, e.g. on every 4th snare hit, or individual words on a vocal track.
•Roll
In Roll mode, the unprocessed signal passes through unaffected until you turn up the Roll slider, see “Roll slider”.
This gradually suppresses the Dry signal while simultaneously raising the Feedback and mixing the delay/echo
output into the Wet signal. The Roll mode is useful for repeat, stutter and glitch effects. For Roll mode, we recom-
mend that the Dry/Wet parameter in the Output section (see below) is set to (or close to) Wet.
q See “Using the Roll function” for an example of how to use the Roll function.
Trig
This button is only functional when the Mode switch is set to the Triggered position. When you press the Trig button
it opens the Input signal gate, which stays open until you release the button again. Think of it as momentarily enabling
an effect send.
Roll slider
This slider is only functional when the Mode switch is set to the Roll position. The Roll slider does three things:
• Turns up the feedback (internally) to unity (100%) or to the Feedback setting on the front panel, whichever is
higher.
This starts happening during the slider throw, to catch a good amount of input signal.
• Closes the input to the delay (you don't want the delay to continue catching the input sound during the roll).
This happens late, with a slight delay - meaning it catches a little bit of sound after you've hit the Roll position.
• Changes the internal mix from dry to wet.
This also happens a bit late, so that if you hit a drum beat perfectly with the roll, you will hear that beat (dry) before
the delay repeats (roll).
! Note that the "internal mix" mentioned above is the signal sent to the "Wet" channel in Roll mode. The "Dry"
channel still carries the dry signal at all times.
