HALF-RACK EFFECTS712
DDL-1 Digital Delay Line
This is a mono delay (where the output can be panned in stereo) that can be synchronized to the song tempo. The
delay can be used as a send effect or an insert effect.
Parameters
CV Inputs
The following CV inputs are available on the back panel of the device:
D Pan CV.
This allows you to control the panning of the delay signal. Connect an LFO to this for moving delay effects, or use
a Matrix pattern to simulate random delay panning.
D Feedback CV.
This allows you to control the amount of feedback (the number of delay repeats) from another device. Useful for
dub-type echoes on certain beats or notes only.
Switching between Unit modes
When you switch between the two Unit modes (Steps and MS), the following rules apply:
D If you switch from Steps mode to MS mode, the delay will be set to the same actual delay time as was used in
the Steps mode.
This means that you can set up an exact rhythmic delay in Steps mode, and then switch to MS mode to adjust it
slightly.
D If you switch from MS mode to Steps mode, the delay is reset to the previously used Steps value.

Description
Delay time The display to the left on the device panel shows the delay time, either as note value steps (based on the sequencer
tempo and the Step Length parameter) or in milliseconds, depending on the setting of the Unit switch.
The maximum delay time is two seconds (2000 ms) while the maximum number of steps is 16.
Note that if the tempo is low, you may reach the maximum delay time at a lower number of steps than 16 (in which
case raising the steps value will not make any difference).
Unit This is where you select whether you want a tempo-based delay (“Steps” mode) or a free time delay (“MS” mode).
In the Steps mode, you specify the delay time in note value-based steps. This means that if you change the tempo in
the transport panel, the delay will maintain its rhythmic relation to the music (provided that the resulting delay time
doesn’t reach the maximum value). This mode is useful for creating rhythmic patterns.
If you change the tempo when using the delay in MS mode, the delay time will remain the same.
See also the note about switching Unit modes below.
Step length Governs whether each step in Steps mode should be a sixteenth note (1/16) or an eighth triplet note (1/8T).
Feedback Determines the number of delay repeats.
Pan Pans the delay effect to the left or to the right.
Wet/Dry If you are using the delay as an insert effect, you use this parameter to adjust the balance between the unprocessed
audio signal (dry) and the delay effect (wet).
If the delay is used as a send effect, this should be set all the way to wet only, since you can control the balance by us-
ing the AUX send controls in the Mixer.
