On the other hand: this would be a central (“global”) configuration option somewhere buried in the Options page, effective for all tracks of the session.
Wouldn’t it be more straightforward if you would pre-initialize the track by yourself based on your needs, and then store it as a preset?
MENU->Evnt then “PRESETS” (GP button #15)
This function allows you to store your current track setup on SD Card with a given name, and restore it later in any other session into any other track.
This way you could create your presets for different situations (e.g. all Velocity values set to middle although no note played)
We can also see this as an alternative to the Clear function -> just load a preset
Yes, I want you to use templates. You don’t need to change the values 256 times, just use the ALL function to set the entire parameter layer to the same value.
