loudness (logarithmically). That is to say, with Audio Taper, if the Delay Feed knob is at 50% then the audio level 
will be 10% (which the ear perceives as half as loud). 

In 

Linear Taper

, if the knob is at 50% then the audio level will be 50%.

Previous firmware version had the 

Delay Feed

 knob work with an 

Audio Taper

, because that's preferred for most 

audio volume knobs since it follows the ear's natural way of perceiving loudness. However with variable 

Feedback

Wet/Dry Mix

, and multiple channels mixing together, the idea of "natural perception" is out the window. We got 

some feedback from users that 

Delay

 

Feed

 seemed to make things too quiet too quickly, so the use of 

Linear 

Taper

 compensates for that. In Version 5, 

Linear Taper

 is not the default but can be changed by the user. 

With 

Linear Taper

, iIf you have a very hot input signal you should keep 

Delay Feed

 below 50% so that it doesn't 

saturate

Runaway DC Blocking – NEW FEATURE!

Hardware on the DLD inputs eliminates most 

DC offset

, but it’s still possible for a small amount of offset to come into 

the systems and problems can occur internally when high feedback magnifies this offset until it causes the whole 
output signal to drift up or down and hitting the rails, causing grave distortion

Runaway DC Block

 protects against this toxic situation, The default is set to ‘on’ and we recommend not adjusting this 

unless you are using the DLD for recording CV sequences with Feedback at or near 0%.
