Hello fellow wiggler,
So you did it, you got a Polymorpher and wonder what to do first ?
Ok, here goes
Start the rack and hold down the big knob, that will get you to the app selector.
Choose the app you want to try.
We suggest to start with the 4 LFOs as they provide instant gratification.
Plug a cable in one of the 4 CV outs and feed it into a CV receptor…voila, 0-10V
Adjust parameters like frequency or spread with the two knobs.
The up/down switch also changed parameters in coarse jumps.
Ok, hold it there…
Press the big knob for 3 seconds…the app selector will appear
Press it again for 2 second and a white square will fill the screen.
You just successfully saved your settings.
Go back to the LFO and adjust the output levels with the trimmers.
Try feeding input CVs to the LFOs and also level those.
Please refer to the full manual for all settings, parameters and CV control of the apps
Upgrading the firmware :
When we build your xOC we always flash it with the latest official firmware
But this is a living project and Max 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 xOC 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 : Version 1.3.6 111021
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 of all 8 channels.
Due to harsh temperature differences in planes and the place you live the resistance will change and so will the outputs.
If you notice a drift (in a Buchla system, lol) you can hold down the blue encoder on start and enter the world of calibration.
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 wait half an hour. By then it should have taken on your working temperature .
Connect a multimeter with a banana cable to output A and the other one your common ground in the back of the rack.
The 2OC will display a new setting for every press on the red encoder.
If you press the left/upper encoder you go one step back…or you dial back and forth with for fast movements
So navigate to the first value which should be 0V.
Check your DMM and if it shows a significant drift dial it in with the red encoder
Advance to the next step and do it 40 times more… dooohh !
Then you will come to the ADC offset.
Make sure to dial this as close as possible to 0
Repeat for all four channels
Then connect a short cable from output D to CV A and make sure your DMM shows 1,2V. If that is the case confirm the offset by pressing the encoder for 2 sec.
Next step is the same procedure but for 3,6V
Set the timer for the screensaver in the next step
And when you are happy save your new calibration
Now make some music and stop obsessing 😉
