NanOS 2.1.0 is now available

We’re excited to announce the release of NanOS 2.1.0. This update introduces several highly requested features, including Incoming MIDI CC, Tap Tempo, IR Loader Bypass for a specific output, MIDI Thru, and other improvements that enhance usability and performance.

We recommend all Nano Cortex users update to NanOS 2.1.0 to take full advantage of the new features. For step-by-step instructions, check out our guide on updating your Nano Cortex.

Added

Incoming MIDI CC

Nano Cortex can receive MIDI CC messages for:

• Bypassing individual device slots

• Controlling expression pedal position

• Tap Tempo

• Tuner On/Off

Tap Tempo

• On device: 

  • Hold Footswitch I to enter Tap Tempo mode. Footswitch I’s LED will blink at the current tempo. Set the tempo by pressing Footswitch I.

  • Exit Tap Tempo mode by pressing Footswitch II.

  • Footswitch I’s LED flashes blue when incoming MIDI clock is sent to Nano Cortex.

• On the Cortex Cloud app: 

  • The Tempo menu now features a tap pad, precise BPM number entry, and the ability to select between global or Preset-specific tempos.

  • Select between external MIDI clock sources (USB MIDI or TRS MIDI).

IR Loader Bypass

Independently bypass the IR Loader on a specific output. 

MIDI Thru

Forwards MIDI messages received via the TRS MIDI input directly to the USB MIDI output.

USB Playback Volume

Set the volume level for audio from a USB-connected device.

Mute Input

Mutes the analog input's direct monitoring path. Essential for re-amping workflows to hear only the processed signal from your DAW.

Mute Outputs

Mutes the analog outputs to prevent signal doubling when monitoring entirely within your DAW.

Keep Reverb and Delay trails on bypass

Keep Reverb and Delay trails when bypassing Nano Cortex (only applicable in when 4-Preset mode is disabled).

Changed

Smoother LED ring operation that shows intermediate steps.

Fixed

Systems stability & crashes

• Resolved critical issues that could cause Nano Cortex to crash or freeze, particularly when downloading a Neural Capture or when left idle for an extended period.

• Addressed a bug that would result in no audio passing through the Nano Cortex if a Preset was loaded that used a deleted Neural Capture.

Audio issues & noise reduction

• Fixed a bug that produced a brief yet audible click when switching between Presets with and without an IR.

• Eliminated unwanted noise that could be heard when loading a Preset with an active Input Gate.

IR reliability

• Fixed an issue where a deleted IR could remain active in a Preset.

• Fixed a bug where an IR could be inactive despite the UI showing it as active when loading a Preset.

Preset management

• The Input Gate now maintains its correct on/off state when loading a new Preset via footswitches.

• Fixed a bug that allowed multiple Presets to be created with the same name.

• Expression pedal assignments are no longer deleted from an unsaved Preset after entering and exiting the Neural Capture menu.

Hardware

• Knobs now operate correctly in Latching mode after returning from the Tuner or Neural Capture menus.

• Improved the device's startup sequence for better reliability.

• A Preset change no longer occurs when enabling 4-Preset mode while Nano Cortex is bypassed.

• Bank LEDs no longer remain lit when loading a Neural Capture.

• SAVE and CAPTURE LEDs no longer stay lit after their operation is complete.
