4ms Dual Looping Delay
Firmware Version 5
Release Notes
August, 2016
Version 5 firmware for the Dual Looping Delay is a major update that adds very significant new capabilities to the unit,
as well as refinements to the features previously existing. Please take some time to read through these notes to help
you get the most out of your new and improved DLD, and avoid any confusions caused by changes to operations.
Updating to Version 5
As for previous updates, use the Audio Bootloader to install the Version 5 update, delivered as an audio wav file. You
can download this file from the 4ms web site here:

Preparation
1.
Turn off system power. Connect audio output from computer, smart phone (remove the phone case to
ensure the cable can connect), tablet, etc. to the
In B
jack with a mono or stereo (either is fine) cable.
2.
For audio monitoring, connect the
Out B
jack to an amp/speaker. Set a low initial volume, as the audio
data file is LOUD!
3.
Set the output level of the computer or phone, and also that of your audio software to 100% volume.
Turn off all audio and vibrate notifications, and close applications such as Facebook that use audio
notification. Any disruption in the audio will ruin the process.
Updating
4.
To enter the
Audio Bootloader
mode, depress both
Reverse
buttons (
A
and
B
) and the
Ping
button while
powering on the DLD. When you see the
Channel A Hold
button turn on (or blink), the DLD is ready to
receive firmware. Release all the buttons.
5.
Begin playing the v5 audio wav file. Immediately you should see red
Channel A Loop
LED blink. The blue
light will flash from time to time as well. Do not interrupt the process! You can monitor the audio by
listening to the
Out B
jack.
Completing the Update
6.
The audio data file for the v5 update is approximately 2 minutes in length. Just before audio finishes
playing, you will see the 3 lamps (Ping, Inf Hold A & B) flash a couple to times before the unit comes up to
its normal operation. Congratulations!
The
Audio Bootloading
process is very reliable, but any interruption or glitch in the audio stream will cause it to fail.
If audio stops before the end of the file and/or the lights stop blinking, an error has occurred and you should try
again.
First verify that the cable is not loose, that all sounds/vibrate/notifications are off, and that you have downloaded the
audio file completely (avoid streaming or playing from the browser).
