Automate and/or smooth Variations on Ableton Live 11.
Smooth Automator allows you to create automations for the Variations, create smooth transitions, either timed, synced, or even manually with a slider.
All you need to do is put the device to the left of a Rack.
No need to ask, it's a Smooth Automator.
If you encounter problems with the device (macros jumping or misbehaving), simply do a "Hotswap" on the device and replace it with itself, that should fix it.
When re-opening a set the devices should work correctly.
If you want to launch Variations via MIDI mapping, check my Variation Launcher add-on device.
