Are there? to lets say… 32/64?
Alternatively it would be neat to simply be able to automate the instrument effects chains directly (the best variant, we could left click to record, use the higher resolution and edithave it all run directly, if it would mean that an instrument would need to be bound to a track, so be it)
or indirectly via the instrument automation device, you could ctrl-shift-m - click a parameter and make it available to the instrument automation device.
I have a feeling the number 8 was chosen more do to visual reasons than anything else.
