Make Noise has released a free firmware update for the Spectraphon dual Spectral Oscillator .

Here’s what’s new:

• Sub-Oscillator is now available as a Sub/CV output mode in SAM (previously only available in SAO).
• Adds option to Delete currently selected User Array and return to Default Array on current slot. To Delete, while holding SHIFT button on the Side whose User Array you are Deleting, press and hold opposing SHIFT button for 2 seconds. For example to delete current Array on Side A, Hold SHIFT-A first, then Hold SHIFT-B for two seconds.

In addition to the new features, the update includes critical bug fixes, and is therefore recommended for all Spectraphon users.

The new firmware is available now from the Make Noise site.
