Notes
- Getting Started with Syntherrupter
- How to Flash the Firmwares
- If you flash the Tiva for the first time or increase the coil number always check ALL settings. You should check it after each EEPROM layout update, too. Just in case...
- This version is not backwards compatible with previous stable releases.
Changes
Changes since v4.2.0-beta.7
- Fixed: New Syntherrupter builds which don't have any settings memorized yet fail to start; the screen remains black (original bug report).
- Added: Sysex command 0x204 to query the firmware version.
Changes since the last stable release (overview). For more details check out the v4.2.0-beta.1 - v4.2.0.-beta.7 release notes.
- Sysex commands. Control your Syntherrupter entirely from your PC using Syfoh or directly by the MIDI file you're playing. All settings and configurations can easily be created, applied and stored on your PC or be embedded into your MIDI files. Very useful for stage performances when there's no time for fiddling around with various settings.
- This also means you don't need any graphical UI anymore if you don't want to use one.
- You can control a lot more things with Sysex than with the UI. You can f.ex. set a minimum ontime.
- You can monitor values (like the duty cycle) in real time.
- (Almost) perfect interrupter signals. The signals are now buffered (buffer duration can be configured with Syfoh) which means that other tasks don't cause any jitter at all (previously not the case).
- Nextion Editor updated to v1.63.3. This version adds support for the latest hardware revision of their intelligent screen displays. It also "fixes" the highly annoying issue of v1.62.x versions not being available anymore.
- EEPROM data management rewritten from scratch. You won't notice much of it but for me it's now much easier and efficient to use while coding. Existing data from previous versions is automatically migrated to the new layout. You get a warning message and can check everything before saving it permanently. The new code also reduces the wear of the EEPROM.
Bugfixes since the last stable release
- Fixed: Rare hanging notes; potentially leading to a crash. The bug has existed since v4.1.0. However, it seems to have been very improbable to hit it so far.
- Fixed: Omni mode doesn't work for some notes. They'd still play as stereo mapped notes.
- Fixed: If the voice limit is reached, hitting a note again is not audible. Especially noticeable with the pedal. This could cause entire parts of arpeggios and glissandos to miss (Example at 01:36 the first glissando is fine, the second one is missing its beginning).
- Fixed: Pedal lifts could be missed.
- Fixed: Channel volume and expression had no effect for notes hold by pedal.
- Fixed: The first few ontimes of a note could have random values (within the coil limits) Causes "popping" noises especially for shorter, low volume notes.
- Fixed: MIDI voice limit didn't work as expected. In fact, it only limited how many new voices could be added at the same time without counting the existing ones. Now works as expected.
