# Synth Firmware 1.2.0

Synth firmware 1.2 focuses on interface improvements and disabling effects when they aren’t in use to free up some of the CPU.

# New Features

- Effects (Rev, Mod, Del) are not activated when not used in a scene
- Dim Mode added to the system settings.
- Interface improvements to help avoid clipping and distortion
  - Master Volume now shows dB values instead of a line
  - Mixer Level meter turns red when clipping
  - Maximum mixer sends set to 0dB instead of +12 (Old projects will still load with the value saved at +dB settings)

- Added screen indicators to help troubleshoot when a Synth isn’t playing a sound
- Added an all note off option to stop hanging notes
  - Access via Main Menu \> All Notes Off

# Fixes

- [GRAIN Burst Ratio parameter values were playing at double the specified tempo](https://backstage.polyend.com/t/grain-engine-external-sync/18042)
- Incorrect engine could load on when mapping PC change options if patches shared the same name
- Freeze when using Layout and Mode knobs on Grid page simultaneously
- Clicking when using crossfaders for Mod \> Rev or Mod \> Del could sometimes occur
- Aftertouch did not work if Pad hit extremely hard
- Preventing hanging of held notes when Local Mode changed to off
- Quickly scrolling the program change mapping list sometimes switched the active patch
- PC change could corrupt the loaded patch and browsers
  - Patch preview removed from PC mapping to prevent this issue

- [Freeze after loading a scene with PC Mappings multiple times](https://backstage.polyend.com/t/synth-hangs-after-filling-all-pc-slots-and-changing-scenes/17847)
- Switching Pages would occasionally result in an empty parameter page
- Main Menu navigation sometimes cut-off

### INSTALLATION GUIDE

[Synth Firmware 1.2.0](https://polyend.com/downloads/synth-downloads/)

Copy the .psf firmware file to your Synth SD card → Firmware folder

2. On the Synth menu navigate to Main Menu → System Settings → Firmware → Update Firmware → .psf file
3. Click the encoder and confirm with Yes
4. After the update create a new scene to initialize the config settings
