    Expander connector (12 pin boxed) for IO-Expander (Midi In/Out + Sega Gamepad connector) (Expander must be ordered seperately) Expander connector (14 pin boxed) for special Nerdseq extensions like a NSA (Nerd Sound Adapter) which are dedicated Cartridges including full synthesizers. Those are totally integrated in the Nerdseq sequencer.

    -> Voltages are too low / not enough current). Check your supply, disconnect some other modules to be sure your supply got 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 8: Numbers, Values And Tracker Basics

    “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 9 As the NerdSEQ got only a small display, the information is splitted logically into different screens. Nerdseq – a tracker based Eurorack sequencer Page 9 User Manual Revision V0.9.9 for Firmware V1.13...
  • Page 10: Buttons And Navigation

    There is much more about trackers, check the links for more informations. I would also suggest to check some tutorials about ‘LittleSoundDJ’ as it is the most similar to the tracker of the NerdSEQ. Though they are some major differences, it gives a clue about how to work with dedicated screens.
  • Page 11 For fast unmuting all tracks you can press SHIFT START for the solo function twice and all tracks are unmuted directly. Nerdseq – a tracker based Eurorack sequencer Page 11 User Manual Revision V0.9.9 for Firmware V1.13 27 February 2018...

    Also here, some are limited to the type which I will describe now. Depending on which track the pattern is created, it is locked to the type of the track (not to the track itself). For Nerdseq – a tracker based Eurorack sequencer Page 12 User Manual Revision V0.9.9 for Firmware V1.13...
  • Page 13: Sequencer Screen

    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 Sample tracks (with each sample track being able to play 2 samples simultaneously, so 4 samples in total at any one time).
  • Page 14 On the right you see the Project Name, the Tempo, the current Global Transpose and if the editor is enabled.

  • Page 17: Pattern Screen

    (plans are to make that changeable) Patch can select a patch which is loaded before a note plays. With it you can change patches with every sequencer step Nerdseq – a tracker based Eurorack sequencer Page 17 User Manual Revision V0.9.9 for Firmware V1.13...
  • Page 18 Keep in Mind, when using notes, the trigger is being used as a gate automatically on note ON / OFF. To avoid that you must add a Kill effect with the value 000. Nerdseq – a tracker based Eurorack sequencer Page 18 User Manual Revision V0.9.9 for Firmware V1.13...

  • Page 21 However they got other relevant parameters like volume or the selected sample. Also the parameter set for the FX columns are different compared to the CV tracks. Nerdseq – a tracker based Eurorack sequencer Page 21 User Manual Revision V0.9.9 for Firmware V1.13...

  • Page 23 (eg make one of the pattern part with less sequencer steps and repeating). Keep in mind that it is possible to create an endless pattern by this. Also notice that if one of the Nerdseq – a tracker based Eurorack sequencer Page 23 User Manual Revision V0.9.9 for Firmware V1.13...
  • Page 24 A special is here that one pattern has 2 groove settings so you can have different settings for the 2 parts of the pattern. Nerdseq – a tracker based Eurorack sequencer Page 24 User Manual Revision V0.9.9 for Firmware V1.13...
  • Page 25 The involved rows will move down behind the copied/inserted area. You can also copy in between different patterns and even from one project to another. Nerdseq – a tracker based Eurorack sequencer Page 25 User Manual Revision V0.9.9 for Firmware V1.13...

    Those can also be switches which show the ON/OFF position then. In the case that there is a diagonal line in the value field, then this parameter will not be changed/touched when the patch is being called.

  • Page 29 One interesting part of tables is to add arpeggios with different speeds. So with a fast transition fast arpeggios can sound like a chord. For that I have a nice cheat sheet to generate arpeggios/chords (taken from chipmusic.org by user LazierGunz): Nerdseq – a tracker based Eurorack sequencer Page 29 User Manual Revision V0.9.9 for Firmware V1.13...

  • Page 34 Volt offset. When calibrated, check again the 0 Volt and the -5 Volt position to be sure they are right. ◦ Now you don’t need to touch the backside anymore so the nerdseq can be placed back in the rack. Switch the CV and MOD offset back to the right position ( 0 Volt ).
  • Page 35: Load Sample Window

    Debug - > turn on some debug output • Soft Reset -> Resets the Nerdseq when needed (works only when Debug is ON) Load Sample window The sample-slot window is to add samples to one of the 12 slots. Those will be loaded into the memory then.
  • Page 36: Recording

    Below the sample-slot window with 6 loaded slots: Recording The Nerdseq got recording facilities with flexible recording sources. For now only basic recording is possible which will be enhanced in the future. Recording can only be done step-based. So only values for each step are being recorded.

  • Page 40: Firmware Update

    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.

    In the end, I am a software developer, inventor and musician and the manual is just one of the things I have to do. Also I, XOR Electronics take no responsibility to any damage that occur to other gear, the NerdSEQ or your body by using the Nerdseq. Please use and handle it with the common sense.
