Updates
It is possible to update the firmware on the Fourays using this page, if your browser supports it.
Versions
This page updates any Fourays to the current release, whichever version it is running now. There is one firmware and it is the latest one.

- v3.100 : Fix egregious off-by-one error with note pitches
- v3.000 : Restructure configuration into pages; support screen offsets; added splash screen.
- v2.200 : Implement standard MIDI CCs 7, 120, 121. Add manufacturer ID to sysex output. Fix gate clock divider config setting.
- v2.100 : Implement configurable gate outputs
- v2.000 : Update UI layouts
- v1.200 : Implemented gate outputs
- v1.166 : Initial release
The current release is 4.000, and the changelog has the detail.
The firmware and the plugin are released together and carry the same number, so use a pair from the same release.
The plugin
The Fourays plugin is a VST3 which presents all of the controls on a panel and sends the MIDI for you. It is built from the same sources as the firmware, and is downloaded and installed from its own page.
Use a plugin and a firmware from the same release. The configuration carries a version, and a mismatched version is refused rather than partly applied. The activity screen reports IGNORED if this happens.
Licensing
Fourays is free software. The firmware, the plugin, the hardware designs and this site are all covered by the GNU General Public License v3, and the sources are on Bitbucket.
There is no warranty, as the licence sets out.
The plugin is built against Steinberg's VST3 SDK, which has been MIT licensed since version 3.8.1. Older advice that a VST3 plugin cannot be GPL licensed refers to the earlier SDK licensing and no longer applies.
