Release Candidate Firmware V3.01 RC4

Thu, 11 Jun 2026 22:12:23 +0200

It's been a while since the last release candidate and my planned release has been delayed. What also happened is that I added even more features, refactored some parts to gain more performance and fixed the few issues with the RC1.

So lets start again with a new release candidate V3.01 RC4 (skipped the internal RC2 and RC3).

Here are all changes:

Audio
- refactoring of the sample and audio engine to gain some more performance
- added loop, pinpong and frame + loop/pingpong functionality for samples.
- added loop start/end/frame positions as a shortcut SHIFT+OK+Increment/Decrement
- added mapping destinations for samples (AUDI SP0-11 START/END/POS) to change the start, end or both
- added resampling screens for the samples so if a sample is too long (or manually by loading the sample with SHIFT+OK) a lower samplerate can be selected
- loading samples in a lower samplerate (allows a longer sampletime) can be selected with or without interpolation
- added 24 and 32bit PCM and float sample support, fixed some sample loading issues
- added Kill command for samples
- added play sample X on audio channel Y for I2C/Multi tracks drummatrix
- added sample OSC mode. If a sample is set to one of the loop options then it can either act like an oscillator (keeps looping) or stops when a track is stopped.
- changed sample wavefile prelisten so it stops only when SHIFT is being released instead of a toggle

Envelopes
- added additional exponential envelope responses (experimental, choose LIN/EXP with envelopetype.)
- updated retrigger behaviour with ADSR envelopes so they are more equal to a typical analogue functionality

Mapping
- fixed mapping 'add pending table ticks' will work also now with XMAP
- added mapping table destinations to fire/restart and stop tables on tracks
- Added new mapping XMAP source command: XSHT is a 1 shot multi row XMAP depending on the raising state of the former row
- Added new mapping XMAP 1Shot destination commands: Multi row XMAP depending on the raising, falling or on change of the source

General
- added a basic Scope (Setup->NerdScope) with 1 trigger (no trig, raising, falling, changing edge) and 4 channels. The input/trigger values are received though the new mapping destinations Global -> SCTV (for the trigger input), SCP1-4 (for the channel input). The 'timebase', enabled channels, trigger level and type can be changed in the scope screen.
- fixed sequencer screen possible glitches on lowest rows (EF-FE)
- added 'delete projectfile' which moves a projectfile to the backup folder
- fixed patch editing for Multi/I2C FX. Fixed create patches, added regular patch editing for I2C tracks
- fixed 'CBPB clock now 1xx' problem which caused an 'out of sync' if switching to dividers
- fixed issue that a new clock or patternorder would be activated already when pressing START to cue something instead of with the upcoming pattern
- fixed local trigger indicator in video pattern
- replaced unused Track 'pattern start position' mapping destination with 'Fire Patch' (TRCK TRKx PTCH) destination. Patch defined by former row
- fixed inconsistency with the sequencer screen use of the last edited pattern
- fixed pattern screen update if euclidean is being changed (showed accidentally on the Launchpad)
- added colours will now also be copied/pasted on the sequencer screen
- added VEX connected PC Keyboard to Midi routing which adds the full support of the midi in functions but then for the PC Keyboard (including polyphony, recording etc) (Setting in the Midi/I2C setup screen. PC Keyboard > Midi Input Port/Channel X and in the general routing you use port/channel x then to be used as track record etc just like it is a midi device).
- fixed possible wrong finetune scaling if 'avoid' was selected for local cv/gate
- updated many copy+paste parts for patterns which adds more 'compatible to each other' fields
- fixed user interface import/export which didn't save the 'Window Lines' colour properly
- fixed track and drum matrix mute and solo with the PC-Keyboard
- added uppercase functionality for all written characters (User Interface screen)
- fixed accidentally change of the trigger type when increasing/decreasing euclidean values in the modular trigger column

MIDI
- fixed hanging MIDI scale note
- added user harmonics from MIDI keyboard (Midi Input Setup Detsination). Changes a new scale (5A/90) to the midi keyboard pressed notes.
- fixed stop of midi notes when entering the midi pattern screen via OK

Trigger16
- added a per-column destination and triggertype for the T16 drum matrix
- updated Trigger16 triggertypes to fully match the local triggers (needs Trigger16 Firmware V1.1 update)

DualChord
- fixed missing note off/gate off issue with dualchord on pattern stop
- fixed 'set dualchord trigger' command
- fixed dualchord trigger to 'other' destinations than the dualchord itself
- added random trigger types to DualChord matching the local track options
- fixed missing (not working) chord types for the 2nd dualchord part (needs Dualchord Firmware V1.3 update)

Tables
- fixed table editing for the transpose column
- fixed table bug where tables using >>> and zero selected allowed notes would cause an endless loop = freeez
- fixed table transposition with and without quantization
- fixed random table transpose (random seed issues)
- changed default for midi tables to 'no retrig' for all 16 rows

Files
- added alphabetical sort of directories (enable in setup screen)
- fixed retries when no sd card could be found
- added additional save test in case of incomplete or incorrect project saves
- added compile time as the save file time
- the save file time is now set to the compile time

As usual, this is a release candidate. It is not intended for productive use as I can't guarantee that they are no unexpected side effects. Also saved projects will guaranteed work for the release version but are not backwards compatible to load with 3.00 or earlier. So be aware to backup your projects / SD Card first!!! (Which is something you should do anyways from time to time)
But with installing it and trying it out/testing you help getting the version ready for stable use. I aim as usual to release as soon as possible.

Please report any issues with that only in this thread here as this is not a stable version.

Download the release candidate below, follow the firmware update rules and if you get stuck there and it doesn't work, read the many threads about it and it will be fine!! Updating the NerdSEQ always works!

Video Expander Firmware V3.0 and info

Tue, 30 Sep 2025 14:50:49 +0200

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):
http://xor-electronics.com/downloadfiles...er_1_1.zip

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: 25)
shaders.zip (Size: 299,59 KB / Downloads: 22)

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.

Firmware V3.0

Fri, 26 Sep 2025 16:03:20 +0200

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!

Release Candidate Firmware V3.0 RC5

Mon, 11 Aug 2025 18:13:03 +0200

I am happy to provide you a new release candidate (as in: public beta) for the upcoming NerdSEQ firmware V3.0 as well as the upcoming Video Expander Firmware V3.0.

This is an update for the NerdSEQ and another update if you also got a Video Expander (VEX).

Please follow this update order:
1. Copy the NerdSEQ firmware (unpacked, 'nerdseq.hex') into the firmware folder of the NerdSEQ SD Card.
2. (optional) Copy the video expander firmware (unpacked, 'vex_3_0_rc1.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.
4. Update the NerdSEQ firmware (follow the firmware update rules https://forum.xor.eu/showthread.php?tid=4 and if you get stuck there and it doesn't work, read the many threads and the manual about it and it will be fine!! Updating the NerdSEQ always works!)
5. (optional) With the new NerdSEQ firmware V3.0 running, update the Video Expander firmware. Go to Setup->Expander FW Update. Choose the firmware file: VEX_3_0_RC1.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 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)!

For the video synthesis functionality please check the latest version of the manual on github:
https://github.com/XORElectronics/nerdSEQ_docs
The manual is not ready and not formated well but all the video functionality is described well in there and it is worth to check it out as many questions will be answered upfront! I will update the manual in the next days so it is ready together with the release.

Check out the new things for V3.0 here:

Release Candidate Firmware V2.03 RC1

Fri, 07 Feb 2025 14:56:22 +0100

This release candidate contains some minor updates/fixes as well as some Dualchord additions:

- Added Dualchord Presets. They are now 4 possible presets per project (Don't ask for more, there is no memory for that). For earlier Dualchord projects the current NSA channel will be automatically assigned to the preset (e.g. if the Dualchord was set to NSA channel 3 then the loaded settings will be stored in preset 3.)
- Preset can be set from the track setup screen (via the menu row or SHIFT+OK+LEFT/RIGHT anywhere in the dualchord track setup), via FX and the mappings
- Added Dualchord Preset Import/Export to/from the SD Card
- Added missing Dualchord LFO FX functions. Added DC Part Mode to the FX (SET FX)
- Fixed wrong clock settings from the Track Setup menu (https://forum.xor.eu/showthread.php?tid=1927)
- Fixed beauty issue with Midi Program Change Mapping input

As usual, this is a release candidate. It is not intended for productive use as I can't guarantee that they are no unexpected side effects. Also saved projects will guaranteed work for the release version but are not backwards compatible to 2.02A or earlier. So be aware to backup your projects / SD Card first!!! (Which is something you should do anyways from time to time)
But with installing it and trying it out/testing you help getting the version ready for stable use. I aim for a release within 1-2 weeks.

Please report any issues with that only in this thread here as this is not a stable version.

Download the release candidate below, follow the firmware update rules and if you get stuck there and it doesn't work, read the many threads about it and it will be fine!! Updating the NerdSEQ always works!

Update: I deleted the release candidate files and closed this release candidate / skipped the stable update for this because of too little interrest.

As usual my little 'disclaimer' with some important information before you update:

- make a backup of your SD Card and especially of your projects
- Old Projects can simply be loaded with the new version
- Firmware updates always work, if it doesn't, then you most probably did something wrong. Check the Firmware update FAQ for some infos.

Firmware V2.01A

Thu, 21 Mar 2024 22:54:22 +0100

This is only a small maintenance update to V2.01A to solve some minor issues and one bigger issue introduced in V2.01. They are no really new features but an update if you used V2.01 is recommended.

Basically as usual all rules with updating, backup etc apply. See more info here on the V2.01 update thread:
https://forum.xor.eu/showthread.php?tid=1774

First the most important fix:

Fixed: Project load of earlier projects is working correctly now with the new CV/Gate screen order

And some minor fixes:

Fixed: glide for finer glides (Project files older than V2.01 do update the glide resolution. A higher resolution is now needed to get a snappier glide, but a finer slow glide is now possible)
Fixed: CV16 Patch LFO (FX SLFO) can change all values now
USB Keyboard: Left/Right CTRL are the same now
USB Keyboard: Windows Key (both) acts as right ALT key (Stop)
Fixed: USB Keyboard from ‘New Project’ can now answer the 'Are you sure' question using Start/Stop
Fixed: Mapping destination Table Tick works now also with the selected Table
Fixed: Automator screen update from mapping changes are more 'relaxed' now and don't cause screen draw block in the automator screen

Firmware V2.01

Sun, 18 Feb 2024 16:12:47 +0100

Another Firmware update V2.01 which was also initially planned as a maintenance update. But in the end I added again some new nice stuff.

As usual my little 'disclaimer' with some important information before you update:

- make a backup of your SD Card and especially of your projects
- Old Projects can simply be loaded with the new version
- Firmware updates always work, if it doesn't, then you most probably did something wrong. Check the Firmware update FAQ for some infos.
- 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 V2.01 without any side-effects)!
- I totally can understand if you are disappointed if your long awaited feature request is not included in this update. I really do my best to get much new stuff in the releases and i keep track on all the hundrets of feature requests. I constantly update my 2do list and change priorities depending on many factors. Please read the FAQ in the forum to find out how I work and how I don't work. In the end, I can never please
anybody. But I do my best to make it better each time.

Here the changelog for V2.01:

updated: CV/Gate pattern screen. Order is now: NOTE, TRIGGER, MOD, PATCH, TABLE, FX....

Firmware V2.0C

Mon, 04 Dec 2023 00:51:46 +0100

Here we are with the new Firmware V2.0C (* Updated)

Another massive free update squeezing even more out of the NerdSEQ hardware!!

This update is so big (and I can't even say how big it is) so I decided to name it V2.0. The naming for V1.28 has been skipped.

As usual some important information before you update:

- make a backup of your SD Card and especially of your projects
- Old Projects from stable versions can simply be loaded with the new version. Projects made with V1.28 Testversion should be able to load but might have some wrong values in the mappings or scales. For the rest they should be 95% compatible as well. If you want to keep the mappings you made then I suggest to make pictures of it and manually insert them.
- Firmware updates always work, if it doesn't, then you did something wrong. Check the Firmware update FAQ for some info's.
- No worries, in case of any issues you can always go back to your earlier version (but can't load project files made with V2.0)!
- I totally can understand if you are disappointed if your long awaited feature request is not included in this update. I really do my best to get much new stuff in the releases and i keep track on all the hundreds of feature requests. I constantly update my 2do list and change priorities depending on many factors. Please read the FAQ in the forum to find out how I work and how I don't work. In the end, I can never please anybody. But I do my best to make it better each time.

Also note: Since the last versions the update will look a bit different around the end of updating. For some people the Progressbar will go back to 0 and some percent. That is totally fine and as long as it says 'Updating Succeed', then everything is fine.

added: Mapping Screen which is the new control center to modulate or map (nearly) everything with everything. In the most easy use-case one would use a CV input or a Midi CC as a source and map it to any other function like the LFO speed or Envelope Attack. Or use one of the CV output results, add an offset, divide by another value like the current pattern row on track 3 and output it inverted on another output. It contains a big amount of sources and destinations which can interact with each other. On top of that they are arithmetic and logical calculations possible to manipulate all the used values. Also conditional functions are added which makes it even possible to create small scripts or apply some live-coding. I created as an example a bouncing ball function or a fully running turing machine with it. 16 variables can be used to be a placeholder for deeper calculations.
added: variable screen which contains 16 editable variables which can be used mainly for the mappings but also for some other functions
added: scaling screen which is now the main function to quantize notes to different scales. They are 90 scale presets and you can create your own user scale including finetuning per note. The scale selection can be different per track, global, for input (like Midi or CV Input) and editing (which shows only the notes within the scale)
added: support for the Multi-IO expander which adds functionality for 3 independent Midi streams (USB Host, USB Device, TRS-A/DIN Midi). I2C support with 2 I2C ports which can be flexible configured, an encoder to dial in notes and values and 3 buttons for new edit modes
added: I2C/Multi Tracktype which mainly controls I2C destinations for 6 columns (notes, pitches), 3 FX, drummatrix (16x Triggers/Gates) and groove. The new tracktype is not only limited to I2C but opens many more functions for the local CV/Gates and Midi sequencing (eg sequence Midi CC or Notes in different styles from the drummatrix)
The I2C/Multi tracktype is also available without the Multi-IO Expander.
I2C Implementations for ER-301, distingEX, Just Friends, 16n/sweet16/f8r faderboxes
added: Midi / I2C Setup Screen and project files
updated: Moved Midi clock out from project to Midi-I2c setup screen
updated: editing of Midi note In source/destination. Sources = 16 Midi channels * 3 midi ports (TRS/DIN, HOST, Device)
added: pattern launch, mute, solo etc via Midi
updated: all midi sending and receiving for 3 port Multi-io routing
updated: In a Midi track the midi channels and overrule channels also support now 3 midi ports (with Multi-IO)
added : recording filters for Midi CC, Channel Aftertouch, Pitchbend, Poly Aftertouch, Program Change
added: Midi input and recording for the 6 I2C columns
added: Midi SPP (Song Position Pointer) support
added: merge function for Trs, Host and Device as destination for midi input
added: Midi Velocity can also be overruled by variables
fixed: sync launch mode. If a new pattern is selected to launch then it wouldn't stop anymore on stop signal.
fixed: table quantize which would play the wrong note in some occasions
updated: new and load project unmutes tracks now
added: Track Scale, Global Scale and Basenote to the Combined FX
added: clone marked values for the sequencer screen
updated: renamed all glide steps to glide resolution
added: NRPN would autodetect 7 or 14 bits reception on input
updated: midi 'record velocity to MOD' settings, also allow input from mappings now for the recording
fixed: slow startup in some situations
updated: NSA firmware update screen to provide Multi-IO expander updates
added: FX overrule also from Mappings nowadded: track clock = Off so the clock for a track can be derived from the mappings (and so individual tracks can be clocked from any source)
fixed: possible out of screen issue in project screen
fixed: filesystem directory where a file would not show up if the backup folder is hidden
fixed: dinsync possible stop pending issue
added: Nerd Menu Twice to enter the mapping screen directly
fixed: note range after transpose
updated: trigger delay editing adds now large in-decrements
added: trigger delay in combined FX commands
added: mapping and variables screens with PC Keyboard shortcuts (F3, F4)
fixed: playback order which couldn't directly jump to the next from random keep
added: Keyboard Num Keys as mapping source
added: Sega gamepad as mapping source
added: import and export for mappings + variables
updated: record behavior when holding the table button
updated: SYNC24 Reset input behaviour
updated: sample decrement of notes, adds volume and sample as well again
changed: Launchpad selection which got an own menu setting now.
fixed: possible Raw Sample prelisten crash
added: X, Y Z modes from Multi-IO
fixed: wrong playing MOD on prelisten
added: General I2C Settings in the midi/I2C Setup screen (modes, leader/follower, address)
fixed: row probability bug
added: Gamepad enabled function (is automatically disabled once when updated from a version < V2.0)
added: launchpad with buttons and encoder functionality for shifting and in/decrement euclidean
updated: reduced sample memory slightly to free some general purpose memory
updated: whitenoise playback for audio player
fixed: stop track when a new pattern was in the queue to play in sync mode
fixed: fixed bug that if a CV16 is assigned to track 8 that the LFO in Automator 0 would not work anymore
updated: top and side view of a midi track to properly show overrule channels
updated: shortened Euclidean text so everything is readable again
updated: removed Midi input enabled setting
updated: midi output clock added different routings: off, trs, host, device and combinations

Revision A:

fixed: execution of Trigger mapping destinations and screen glitch
added: Midi Note + Pitchbend to mapping destinations
added: force value to destination command for mappings so selected values will always be passed to the destinations

Revision C:

added scale screen update if changed by mappings
added mappings: Pulse,Start/Jump,Stop sequencer,note2pitch
updated some screen updates if changed from the mappings
added Execute multiple Mapping command as mapping command (nice to create mapping 'macros')
updated slow LFO so the speed is more real again.
added SHIFT+START in marked mode with playing player to start selected patterns
fixed bug with sega gamepad which saved the wrong settings (needs new gamepad setup)
fixed wrong Midi note off if scaled and played from external keyboard
fixed scale function if used from mapping etc and not from a track
added new shortcut for groove to increment/decrement all rows at the same time (SHIFT+OK+CURSOR UP/DOWN in the first row)
added fix so a CV16 will also be initialized even if no track is assigned (so it can be used directly from the mappings)
fixed player functions if a track is externally 'clocked' by mappings
fixed global transpose from mapping
fixed table CV Input so it can be used from multiple tables

And as usual some minor small things that came along the way or needed to be done...

The final manual will follow up in the next days, but for now you can check already the preliminary manual for V2.0 which covers nearly everything:
https://forum.xor.eu/showthread.php?tid=1702

Also, mapping examples will follow up in the next days, too!

The new firmware is attached here, download it, put it in your firmware folder and update following the usual firmware update instructions.

The Firmware and the manual are also always available on the XOR Website:
https://xor-electronics.com/nerdseq/

Don't forget to spread the word, make videos, because that is what's needed to continue adding new features!!
A fancy silly release video will follow up,too of course.

Enjoy the update!
