I asked chatgpt for better placement of my melody notes in nerdseq, this is my first attempt at it.

Here is all info on how to update your Video Expander to V3.0.

First be sure your NerdSEQ itself is running at least on firmware V3.0, else the update is not possible.

Next, it is important that the video expander is already running properly, that includes that it is enabled in clone mode and that a connected USB keyboard does work as well (which means, both ribbon cables, the 12 pin and the 14 pin must be connected directly to the NerdSEQ. Using the 12 pin cable through the Multi-IO and then to the NerdSEQ will not work!)
If you can't test the USB keyboard connection, then you can see if it is working by going to the video setup (Video must be enabled and working on ' clone') Setup->Video Expander. Press OK there to get to the Video setup screen, navigate to 'Save and Restart'  and press OK. If it doesn't 'Fail' and restarts the video expander properly then the communication should be fine. If it fails then you got most likely a problem with your 12 pin cable connection. You could try to remove and insert it a few times (!!! ONLY IF THE POWER IS TURNED OFF !!!)  on both sides and/or turn it around to fix a possible dust problem. Also take care that you don't break the SD card on the Video Expander when inserting the 12 pin cable. 

If that is still not working then it might be a bad 12 pin cable (could work fine for Midi, but different pins are used for the video), but it can also be a bad SD Card on the Video Expander itself.
For the latter, check if the SD card shows the correct amount of capacity. It must be formated with FAT32 (all other formats won't work) and the following files should be on the card (you could try to format the card and unpack the files on it):

Assuming everything does work as expected:
Download the latest Video expander firmware and a starter-collection of some animations here (or on the XOR Website):

  vex_3_0.vex (Size: 1,33 MB / Downloads: 30)
  shaders.zip (Size: 299,59 KB / Downloads: 25)

The firmware file vex_3_0.vex goes into the firmware folder of the NerdSEQ SD Card.
The shaders.zip should be unpacked on the NerdSEQ SD card so it will create a folder on the SD cards root.

Insert the Card on the NerdSEQ again, turn on your system. Go to the NSA firmware update screen:
Setup->NSA Firmware update

There choose the file vex_3_0.vex. (If it doesn't show the file then you probably didn't copy it into the NerdsSEQ firmware folder or anything like that).
Start the update (update now) and after a fast check it should start uploading the new firmware. You can see the progress and after a short while it is finished, the VEX is restarting and you are ready.

All other info about the new Video functionality can be found in the manual.

This is it! The latest MAJOR Firmware for the NerdSEQ and this time also a massive update for the Video Expander (VEX).
Welcome V3.0!

As usual loads of new features, fixes and if you got a Video Expander then you get also a Video Synthesizer for free! If you don't then now is the time to get your hands on a VEX ;-) 

Important information before you update!!!

- make a backup of your SD Card and especially of your projects (can't stop repeating that!!)
- Firmware update FAQ for some infos. https://forum.xor.eu/showthread.php?tid=4
- No worries, in case of any issues you can always go back to your earlier version (but can't load projects that have been saved with V3.0 without any side effects, The VEX firmware 3.0 will work well also with older NerdSEQ versions)!


Please follow this update order (important for the VEX!!!):
1. Copy the NerdSEQ V3.0 firmware (unpacked, 'nerdseq.hex') into the firmware folder of the NerdSEQ SD Card.
2. (optional) Copy the video expander V3.0 firmware (unpacked, 'vex_3_0.vex') into the firmware folder of the NerdSEQ SD Card.
3. (optional) Unpack the 'shaders.zip' file onto the NerdSEQ SD Card root (Unpacking will create a folder on the NerdSEQ root called 'shaders'.) The shaders in that folder are a collection of fragment shaders taken from different (open) sources. Most of the shaders run as they are (all files that start with SHxx) but are not enhanced yet to be used with all the NerdSEQ modulations. All shaders that got proper names (eg PLASMA.FRAG) are optimized and extended with NerdSEQ modulations.
4. Update the NerdSEQ firmware.
5. (optional) With the new NerdSEQ firmware V3.0 running, update the Video Expander firmware. There is no need to disconnect any other expander. Go to Setup->Expander FW Update. Choose the firmware file: VEX_3_0.VEX and press OK. Choose Update Now and it will start the update. Once finished it will show the detected new video expander firmware.
The Video Expander must be enabled (in clone mode) and fully working already to be able to do the update. That means also that both cables, the 12 pin (midi) and the 14 pin (NSA) ribbon cables must be connected with the NerdSEQ (and be sure you don't break the SD Card if the 12 pin cable has not been installed yet. The usual hotplug rules apply)!
6. Enjoy!

Hello,

I was practicing using the input to record patterns coming from the Sh-01a. Here's 5 of them

Does someone know if I have to add something to this mapping behavior? See picture. I would like to use a midi program change to select a row and play the row in the sequencer. It works, but it somehow re-triggers the row, so my patterns only can play for 16 steps instead of a longer pattern of 64. 

Somehow with this mapping it will not stop playing as well, so maybe it gets a midi start message in a loop.

Does anyone know if it is currently possible to have triggers start at random given times, controlled from the random ranges menu? 
Basically I would be looking at giving the triggers values within a range of 01 up to 0F (delayed triggers). I can only find ratcheting and gate length.

Does anyone with the video i/o expander use a Mac KB with it. 
Just wanting to know if it works. The product blurb says you can use a usb keyboard/pc computer. 
Checking before I get on board. There’s no way I’m buying a pc kb :)

Thanks

As i for some reason don't own a multimeter to check my assumptions, can someone please help me find out which note or pitch value corresponds to a perfect 0V (or is closest to 0V) when the cv Outputs are in +/-5 V Range?

Cheers

Some unexpected behaviour with midi note off velocity coming straight out of Nerdseq (multi io TRS, fw 3.0 RC2).
Note Off velocity always resets to/sends value 127, regardless of the set value in the pattern.
