Please add something like Mixer menu > Mixer Track > 'Convert Fx Slots into Patcher'.
This (macro?) would take Fx Slots 1 - 10 of the selected Mixer Track and replace them with a single Patcher instance, that contains everything that's replaced.
What if a plugin can't be loaded into Patcher?
Pop up prompt:
- Abort.
- Load what can be loaded.
- Load multiple Patcher instances with incompatible plugins in-between.
