• Time A center + Time B center: 1V/octave tracking compensation

The tracking of the Time CV jack when the channel is in Unquantized Time Mode can be adjusted to compensate for

keyboards or sequencers that are not accurate, or to provide alternate tunings. See the earlier section for a discussion on

Unquantized Time Mode and Resonant Delay patch ideas. When you flip both the switches to center, the DLD will

automatically set the Delay Feed parameter to 100%, so that the Delay Feed knobs are free to adjust tracking. Also, the DLD

will automatically enter Unquantized time mode. To calibrate, you should input a clock or VCO of about 50Hz - 100Hz into the

Ping jack (the Ping and loop lights will not flash, that's OK!), turn the Time and adjust Feedback until you hear a resonant

sound. Input a 1V/octave CV signal into the Time CV jack (i.e. from a sequencer or a keyboard).

•

Adjust tracking for Time A CV jack: Press and hold Infinite Hold A while turning the Delay Feed A knob

•

Adjust tracking for Time B CV jack: Press and hold Infinite Hold B while turning the Delay Feed B knob

Releasing the button will temporarily lock in the value of the knob (this prevents accidentally bumping the knob while testing

the setting). With the Delay Feed knob at center, the tracking is 1.00V/octave, at minimum it's 0.75V/octave, and at maximum

it's 1.25V/octave.

• Time A up + Time B up: Exiting and saving changes (and firmware version)

With both switches up, the firmware version is displayed on the button lights. See above section.

•

To exit System Settings Mode without making changes, flip both Time switches up and briefly tap all five buttons

•

To save your changes and exit System Settings Mode, flip both Time switches up hold down all five buttons for 8

seconds.

Calibration Mode

Your DLD has been calibrated at the factory and should not need re-calibration. Hardware hackers should be aware that the

calibration data is stored in FLASH memory at

re-calibrate itself on boot. Make sure nothing is plugged into any CV jacks the first time you boot after erasing this sector.

The zero-point of the CV jacks, as well as the DC offset of the audio output jacks can be adjusted. Contact

[email protected] if you believe your DLD needs to be re-calibrated and we will step you through the process.

RAM Test Mode

The DLD is static-sensitive and care should be taken to not shock the unit with static electricity.

If you believe the DLD has been damaged, the RAM chip can be tested.

Unplug all cables. Power the DLD off. Flip Time A up, and Time B down. Hold down Reverse A, Hold A, and Hold B. Power

the DLD on, and release the buttons when Reverse A turns on.

Watch the lights. After a moment, the Reverse B button will turn on. After another moment, the lights will display if there are

errors. If there are no errors, all seven lights will turn on (the red light, the blue light, and the five buttons).

If your DLD has some lights off, or if the lights flash, contact [email protected]

Factory Reset

A factory reset is not necessary unless you have changed System Settings.

To do a factory reset:

Unplug all cables. Power off the DLD. Flip Time A down, Time B up. Hold down Infinite A, Infinite B, and Reverse B. Power

the DLD on. Release the buttons, the four Reverse/Infinite buttons will flash.

Now, flip Time A up, Time B down. Hold down all five buttons (Rev A, Inf A, Rev B, Inf B, Ping) for 10 seconds. Release the

buttons when you see the lights make a chase sequence. Power off, and power back on. The DLD has now been reset to

factory settings.
