Manuals and firmware for every XOR module. No registration, no account, no e-mail address first.

Manuals

The user manual is the full reference, in English, German, French, Spanish and Dutch. The field guide is the same ground condensed for learning, and the mapping field guide does the same for the mapping screen. Read them on this site, or download them: dark for reading on a screen, light for printing.

Firmware

Every firmware here is the result of nine years of continuous, free updates and endless hours of coding and testing — for every unit, including the first production run, and much of it built from what users asked for on the forum.

Read the release notes before flashing, particularly for anything marked updated or changed.

Every file below goes into the /firmware folder on the NerdSEQ’s microSD card, or is sent over MIDI with the NerdSEQ backup tool (NerdSEQ V3.03 or later). The user manual explains each update step by step.

Support the updates

If an update made your module better and you would like to say thanks. Entirely optional — updates stay free either way.

For developers

For building on the NerdSEQ rather than playing it: how mappings are coded, the project file format, and more to follow.

Older versions, and getting stuck

Every past firmware release is kept on the forum, which is also where beta builds are tested before release.

Updates are very reliable. If one does go wrong — the power was cut part-way through, say — run it again; that almost always sorts it out. If the module still will not start, write to us: nothing here is unrecoverable.

Expanders without their own firmware

The IO, 2HP MIDI, ART and Sega Gamepad expanders take their behaviour from the NerdSEQ firmware itself, so there is nothing separate to flash — updating the sequencer updates them. The Video-IO, CV16, Trigger16 and Multi-IO expanders and the Dualchord carry firmware of their own, listed above.
