What you will need:

  • the module to update
  • your eurorack case with power supply
  • a USB-B printer type cable or micro-USB cable depending on the module
  • a windows or MAC computer

Updates available:

  • 14/04/2021: Dual ADSR v1.1: Solves issues with the cycle mode (download and extract), update if your module hangs when changing A or D times in cycle mode
  • 23/05/2022: DCO (2021 new version) v1.4: added MIDI channel selection (download and extract)
  • 11/06/2022: DCO/uDCO V1.7: FM turned off for the uDCO in MIDI only mode to avoid drifting pitch (download and extract)

Samples/S-909/S-LD:

!IMPORTANT!! Be gentle with the module internal parts and the USB-Micro connector. Only handle with care and put your fingers where absolutely necessary. Check the back of your init, for marking either RevB or RevC. Please note: RevB units might not update due to a USB spec issue with a delivered batch of stm32 micro-processors. Try at your own risk (although the risks are low). The firmware updates were only advertised for S-LD units. Also the “Samples” RevB units don’t have the slide switch, so you can’t acces the toms sounds or choke option. This messy situation is occuring mostly because of the chip shortage and the small batch sizes that came with it. If you really need to update to a different version, please return your RevB Samples or S-909 and order the S-LD instead.

For RevC hardware:

  • 06/06/2022: 606 firmware for S-LD hardware (download and extract)
  • 16/06/2022: S-LD firmware with hihat gate-based length, shorten the hihat sound by sending shorter trigger/gate signals (download and extract)
  • 07/07/2022: 707 firmware for S-LD hardware with hihat gate-based length (download and extract)

For RevB hardware:
