Page 9: Basic Overview
Basic Overview The upper sketch shows a basic relation between the several function blocks of the NerdSEQ. Note that several functions can manipulate each other as well which helps to create complex sequences. In the most basic way, the sequencer selects a pattern to play on a track. This pattern sequences the notes/triggers etc.
Page 10: Getting Started
-> Voltages are too low / not enough current). Check your supply, disconnect some other modules to be sure your supply has enough power. (And be sure the NerdSEQ is working properly) Next there will be a guide through some basics, related to values which you find back in most trackers.
Page 11 “F-5” means Note F on octave 5. “D#2” is the note D sharp on octave 2 (half tone higher than D-2) The exact look of the notes can differ between the trackers. With the NerdSEQ the notes are filled in like in the example.
Page 12 There is much more about trackers, check the links for more information. I would also suggest to check some tutorials about ‘LittleSoundDJ’ as it is the most similar to the tracker of the NerdSEQ. Though there are some major differences, it gives a clue about how to work with dedicated screens.

Each track is dedicated to one output channel -> Track 1 for CV1, Trigger1 and MOD1 With the NerdSEQ, by default, there are 6 CV/TRIGGER/MOD tracks and 2 Audio tracks (with each audio track being able to play 2 samples or waveforms simultaneously, so 4 samples/waveforms in total at any one time).

Page 109: Recording / Live Input / Midi Input
Recording / Live Input / Midi Input The NerdSEQ has recording facilities with flexible recording sources as well as live manipulations through the CV/Gate inputs or via Midi. Recording can currently be done step-based. So only values for each step are being recorded. The needed parameters can be initialized in the Project screen →...

A (6 Button) Sega Gamepad is able to provide the following buttons: Start, A, B, C, X, Y, Z and Mode. Gamepads with additional buttons (like shoulder buttons) are available, but only the mentioned buttons are compatible with Sega systems.

Page 116: Expander Modules
There are several expander modules which enhance the functionality of the NerdSEQ. Midi Expanders • IO-Expander. It enhances the NerdSEQ with a Midi-In, Midi Out (DIN5) port and a connector for a Sega Gamepad controller. The Midi functionality is for clocking in and output, to play and record from Midi (Midi→CV Conversion) and also polyphonic multi channel midi recording and sequencing.
Page 117: Nsa (Nerd Sound Adapter) Expanders
NSA (Nerd Sound Adapter) Expanders You can use up to 4 NSA expanders with one NerdSEQ. All NSA Expanders are connected to the NSA port of the NerdSEQ, either directly or daisy chained from one to the next expander.

Additional to the notes the following effects/modulators can be applied for each output: Glide: For each CV output there are Glide settings. These work just like the glide setting on the NerdSEQ itself with the 2 parameters Speed and Steps.
Page 119 The LFO’s can be started and will run endlessly. There is also a command which resets the LFO, so the waveform starts over. NerdSEQ – a tracker based Eurorack sequencer Page 119 User Manual Revision V1.26 for Firmware V1.26...

Page 121: More Video-Io
More Video-IO Figure 28: More Video-IO Expander The More Video-IO Expander adds a composite and a HDMI video output to the NerdSEQ as well as a USB connector, so a USB Computer Keyboard can be used. The Video Expander is always set to be NSA4, so you can’t use any expander on Channel 4.
Page 122 Expander. Please use and handle it with the common sense! In its’ basic use the expander can be used to clone the NerdSEQ screen onto a big screen. To enable the Video Expander you got to run at least the NerdSEQ firmware V1.25. In the Setup Screen you can choose the Video expander to be disabled, enabled with USB function only and as the clone function.
Page 123 A connected Computer Keyboard (PC Keyboard) allows easier editing as many functions of the NerdSEQ can be accessed from the Keyboard directly. It can be also used to insert or play notes directly since 2 note-octaves are directly mapped onto the keyboard. Notes can be played from the sequencer screen and the current track is being played from the keyboard (or multiple if tracks are set to poly-midi mode).
Page 124 (Like many HDMI screens got a 16:9 ratio and the NerdSEQ screen will be horizontally stretched then to fill the whole screen which might look a bit ugly with wide strechted letters. You might want to add Left and Right overscan then to adjust that then.)

On success it will start to flash the firmware. Do not remove the SD Card or power off the NerdSEQ/Expander while updating. And do not worry if that happens either. If an expander is unresponsive in normal operation, you can try to flash it again.
Page 127: Launchpad Integration
It only really makes sense to use the LP integration with colours as you can recognise the parts very easy on the NerdSEQ screen and the LP Pads. The LP will show the upper 8 rows of the Sequencer screen and follows the scrolling of the screen.
Page 128 LP explanation the SHIFT button is the one on the LP (Button H) and not the one on the NerdSEQ) Also this is the same function as if using SHIFT+START with the normal NerdSEQ keys. The Matrix Pads/Buttons also have more functions when combined with the buttons to the right.
Page 129 Within patterns (either selected with the LP or with the NerdSEQ), the LP will have different functions. Figure 29: Pattern Screen -> CV/Gate Track In a Pattern Screen of a CV/Gate track you can insert or remove triggers. The matrix shows all 64 steps and by pressing a button you can insert or remove a trigger.

Page 131: Firmware Update
Midi controller 78 will turn off all notes Firmware update A new firmware can be reliably flashed into the NerdSEQ to fix bugs and add new features (and there will be a lot of new features!) For that you need to put a new firmware file onto the SD card in the \firmware folder. Be sure the file is named ‘NerdSEQ.hex’.
