Infinity Looper SD Card Format and Upgrade Procedure

The Infinity ships with an 8 GB microSD Card capable of 2 hours of audio recording divided among up to 50 presets.  As described in the Infinity User’s Guide on Page 48, each preset’s maximum recording time depends on three factors:

1.       Size of the microSD Card

2.       Number of Presets

3.       Multiplier Value

The Pigtronix Infinity Application allows users to reformat the Infinity’s microSD Card for different numbers of presets to balance the required length of loops with the necessary number of presets.  If you need longer loops but don’t require as many presets, reformat the Infinity for fewer presets using the Infinity’s Application Menu Bar: Tools->Edit Preset Structure.

Changing the number of presets re-formats the microSD Card and erases all Audio and Preset Settings currently on the Infinity!

For users who need longer maximum loop time and more presets, the microSD Card can be swapped for a larger one up to 32GB.

In order to successful upgrade your microSD card, please carefully follow the instructions below. This process is technical and should ONLY be performed by knowledgeable computer users.  Users who do not know what they are doing risk serious damage to their computer. Pigtronix is not responsible if you accidentally reformat your computer’s hard drive instead of the microSD card.  These instructions are provided for reference only.

· microSD Card’s used in the Infinity MUST be Class 6 or Class 10.  Below are two examples of cards that are compatible with the Infinity:

16 GB Class 10 SanDisk microSD Card

32 GB Class 10 SanDisk microSD Card

· Using a #2 Phillips head screw driver, remove the back of the Infinity.  Removing and replacing the Infinity’s back cover are the only times you will need any tools.  DO NOT USE TOOLS INSIDE THE INFINITY!

Removing the back of the unit to replace the microSD Card does not automatically void your warranty.  Your warranty will only be void should you cause any unreasonable damage to the internals of your Infinity: Spilling liquids inside your Infinity, physically damaging the internals with tools (no tools should be used inside the Infinity), unauthorized repairs, etc

· Depending on when your Infinity was manufactured you will have one of the microSD Card holders pictured below.

.  For early Infinity’s the microSD Card holder will look like the image below.  To remove the microSD Card, push on the microSD Card itself from right to left until you hear a click.  Release the microSD Card and it will partially eject itself from the holder.  Carefully grab the microSD Card and pull right until it is free.  To insert the new microSD Card, hold it as pictured (with the notch pointed up), insert it into the holder from the right, and press until you hear a click.

.   For later Infinity’s the microSD Card will look like the image below.  To remove the microSD Card, press your finger on the metal cover and slide it left.  You will feel a slight click once it is unlocked.  Once it is unlocked, CAREFULLY flip the cover to the left; doing so roughly can disconnect the cover from the rest of the holder and if you are unable to re-attach it the unit will have to be sent to us as an out of warranty repair.  Once the cover is freed the microSD Card can be lifted out of the holder. To insert the new microSD Card, hold it as pictured (with the notch pointed up), and place it into the holder from above.  There is a complementary notch in the holder that will hold it in place.  Then CAREFULLY flip the cover to the right, press it closed, and slide the cover to the right.
