Striso board firmware v2.1.2 - 2021-10-28
Striso board firmware v2.1.x has an improved button read algorithm, which for optimal functioning needed some hardware changes (hardware rev1, with small black buttons). It does work with rev0 hardware too (small white buttons), where crosstalk between buttons is much reduced, though the signals are a bit more noisy. Feedback welcome!
To update your Striso board, connect the USB cable with the settings (square) button pressed, now it should attach as a flash drive. To update the firmware just copy the attached .uf2 file to this drive, after which the device applies the update and resets.
Changes compared to v2.0.5:
Added
- Free transpose with up+down buttons pressed. With this mode the pitch of one button can be transferred to another button.
- Option to flip layout (rotate 180 degrees) with settings + B3
Changed
- Increased button sensitivity, easier to reach maximum press
- Include number in product string to distinguish MIDI devices when multiple Striso boards are used
- Red led when transpose is out of valid range
- Button read algorithm rewritten, reducing crosstalk and lifting the four corner limitation
- Custom protocol button messages new format
- Stuck note detection improved (dynamic zero level detection). Feedback welcome!
Fixed
- Clamp pres during portamento and fix portamento for very light presses
