Installation
- Tiva Flash utilities and drivers can be found in the repository under Tiva_Flash_Utilities
- To update the Nextion firmware over USB you need at least firmware v2.0-beta-1 and the Nextion Editor. On the Syntherrupter, go to Settings->USB FW Update. Connect the Syntherrupter to your PC. More infos about updating the Nextion firmware with the Nextion Editor can be found in their documentation, chapter 2.1 and chapter 4
Notes
- Since the amount of coils that can be controlled by the Syntherrupter has to be set at compile time I attached Tiva binaries for 1-6 coils.
- If you flash the Tiva for the first time or increase the coil number always check ALL settings. You should check it after each update, too. Just in case...
- Sound quality is directly affected by the number of coils. Therefore you shouldn't flash a firmware with more coils than absolutely necessary. Remember, you can reflash at any time. To improve sound quality when not all outputs are active, make sure all of the inactive outputs have no MIDI channels assigned.
- Nextion firmware versions 3.0.1 or higher are not compatible with Tiva firmware lower than v3.0.1.
- Tiva and Nextion firmwares >=3.1.0-beta.2 are not compatible with any previous versions.
Big Changes
- See Release v3.1.0-beta.1 for the other important changes since v3.0.2
- Added support for the MIDI command "Pan". You can now place each coil with a slider between "left" and "right" allowing awesome stereo effects - if the MIDI file is using it. By default it is disabled.
- Rewrote the way output signals are generated. This allows much cleaner pitch bending (especially with fast changes). There may me some cases where the sound quality is worse than in previous releases. Pretty rare and IMHO not that bad compared to the benefits.
Small changes
- Shifted ADSR programs by 1. Program 0 now disables ADSR.
- Testing revealed copy paste errors making the previous release unusable. direct MIDI in should work now but is still untested.
