Hello fellow wiggler,
So you did it, you got a Time & Triggers and wonder what to do first ?
Ok, here goes
Start the rack and marvel at the blinking lights.
We have programmed a set of different trigger outputs for you to experiment.
You will find some straight multipliers and dividers, some euclidean sequences and a random voltage generator on the purple outs.
Plug one or more shorting bar into the outs to connect them directly to the ins of the lower part of the module.
You will find two Bernoulli gates to the left and two swing or ratchet generators to the right.
For details about every trigger mode please refer to the full manual of the original Temps Utile which the Time and Triggers upper part is based on.
Upgrading the firmware :
When we build your xTT we always flash it with the latest official firmware
But this is a living project and Patrick and the crew are constantly working of new versions
So if you find a new one on this site that is not displayed when you start your xTT you can update it very easily .
You need three things :
A mini USB cable
The Teensy uloader program: https://www.pjrc.com/teensy/loader.html
The latest firmware which is at this moment : 2TTs(cope) 09Dec21
Install the loader and start the application
Drag the firmware file into the small loader window
Press the green button
Unscrew the module from your rack and place it on a non conductive surface
Plug in your USB cable and turn on the rack.
Press the button on the Teensy………
The uploader should start flashing the chip and after 3 seconds you are up to date.
Don’t be scared, it’s almost impossible to brick the module.
When we build the module we do a full calibration .
Due to harsh temperature differences in planes and the place you live the resistance will change and so will the outputs.
The 2TT does not have a high performance DAC like the xOC but the built in one will do fine for non-pitch-critical CV
Make sure to press NO when it asks to use defaults or you delete the calibration done by us.
But no panic, there is a second stage where you need to save if. If it happens just switch it off.
Turn on your rack and make some tea. By then it should have taken on your working temperature .
Connect a multimeter with a banana cable to a purple output and the other one your common ground in the back of the rack.
The xTT will display a new setting for every press on the right encoder.
If you press the left encoder you go one step back…or you dial back and forth with for fast movements
Check if your numbers dial correctly back and forth while you turn.
If they seem flipped, press the upper button and try again.
If one is good and the other is not press again and try again until it fits.
There are 4 possible setting to set this right….
So navigate to the first value which should be close to 0V.
Check your DMM and if it shows a significant drift dial it in with the right encoder
Advance to the next step and do it a few times more…
Notice there is a small offset caused by everyone’s rack at 0V..you can add that offset to your other values if you like tighter octave jumps
Now you will get to the ADC offset.
Make sure to dial this as close as possible to +-0
Fluctuations of +-10 are totally normal..we measure up to 4096 here
Set the timer for the screensaver in the next step .. we suggest 10 seconds
As a last step set the OLED of timeout to 10 minutes for example.
And when you are happy save your new calibration
Now make some music and have fun experimenting with the Module 😉
