FlatSix Modular Firmware Uploader

Introducing the Nocturne Alchemy Platform – a flexible eurorack module series that redefines versatility and creativity. Each module within the Nocturne Alchemy Platform shares the same robust Arduino-based hardware, allowing you to effortlessly swap functionalities through our intuitive web firmware loader. By purchasing one module, you gain access to the full range of available firmwares, including our current creations, Slight of Hand and Arp Of Darkness as well as others that are planned for future release! This innovative approach means your module can evolve with your music, with new and exciting functionalities just a simple firmware update away. Embrace the magic of endless possibilities with the Nocturne Alchemy Platform. 

This is a firmware uploader for Nocturne Alchemy Platform  modules such as Slight Of Hand and Arp Of Darkness. It only works in Chrome on a Mac or PC. You will need a USB-A to USB Mini cable. If you don't have one laying around, you can find many inexpensive ones on Amazon

Slight Of Hand

V1.5.4 - 01/24/2026 

This is a firmware upload for the arduino-based module Slight Of Hand.

Bug Fixes & Enhancments:

• The portamento control has been optimized to feel more musical with 70% of the potentiometer dedicated to the faster portamento speeds and 30% of the knob dedicated to ultra slow experimental speeds. It's a feel thing. 
• Fixed a bug that could lead in rare occasions to the module calibration de-calibrating  
• This patch primarily is a code optimization to allow the firmware to run more efficiently as well as to simplify development for open source developers wishing to modify the code.  
• Slight Of Hand GitHub Repository 
• Firmware 1.5.4 User Manual (With Firmware Flashing Instructions 

Arp Of Darkness

V1.3.2 - 02/25/2025 

This is a firmware upload for the arduino-based Arp Of Darkness. 

New Features:

• Save sequence - Allows the user to save the current sequence buffer to EEPROM 
• Load saved sequence- Allows the user to immediately load the saved sequence and begin playback
• Cued loading of sequence  - Allows the user to cue the sequence to load and playback on the first note of the next loop 
• Clear: Allow the user to clear the current sequence buffer  
• Boot to sequence: By default, the Arp Of Darkenss now loads in the saved sequence on startup 

 Bug Fixes & Enhancments:

• Fixed bug with Octave down long-press to shift playback modes not supressing the octave shift causing accidental octave down shifting.    
• Firmware 1.3.2 User Manual (With Firmware Flashing Instructions) 

Seventh Summoner

V1.1.0 - 09/07/2025 

This is the latest firmware upload for the arduino-based Seventh Summoner. 

New Features:

• New "Slight Of Hand" mode - Allows the user to boot into a CV Keyboard mode that functions like the Slight Of Hand module by simply holding the Shift/High C button during power on and boot.  

Bug Fixes & Enhancments:

• Fixed a critical bug where in rare occurances calibration data could be corrupted and zeroed out due to EEPROM protected address being overwritten resulting in user having to recalibrate the module 
• Firmware 1.1.0 User Manual (With Firmware Flashing Instructions) 

Shroud Of Turing

V1.2.0 - 02/25/2026 

This is the latest firmware upload for the arduino-based Shroud Of Turing. 

New Features:

• The Shroud of Turing is a 16-bit performance-focused shift register sequencer with musical quantization, inspired by the Turing Machine. It generates pseudo-random CV sequences that can lock into repeating patterns or evolve over time. What sets it apart is the ability to quantize output to custom scales built from the included keyboard, with six memory slots for saving and recalling your favorite scales in real-time.
