Scene list empty after loading user-saved scene

Bug Description

I started to encounter this bug after some time of working with my own scenes.
When I load my scene in most of the cases the list of scenes and presets get completely wiped out and only rebooting the Synth can bring back the list. I did not do anything crazy with these scenes, just started with init scene, loaded some presets, made some adjustments and also assigned presets to Program Change slots.

I understand this might be not easy to reproduce so I can supply the scenes that are causing the issue if the team wants to investigate. I’m also providing a link to video.

Steps to Reproduce

  1. Load some random user-saved scene
  2. Observe that after loading scene list is empty as well as preset list
  3. Reboot to restore the scene/preset list

Occurrence / Frequency

Sometimes

Found in Firmware

Some more findings:

  • This issue looks to be only occurring for scenes that have Program Change mappings
  • For example: if you load scene “A” with 8 PC mappings and then you load scene “B” with 8 mappings it will wipe out the scene/preset lists.
  • After emptying the list the Synth can still produce the sound for the loaded scene but only a reboot can restore the list.
