I would like to share an update for the Multikey addon, which I constantly use when animating. Either when I need to change a complete animated pose, or to change the pose for a whole walk cycles. It can be download for free from Github.
I've added now a new feature for scaling the selected keyframes values of the selected controllers, using a multiply value. Instead of selecting everytime each of the curves in the graph editor and scaling them, you can now do it directly and quickly in the 3D viewport.
The main purpose is eventually to work as much as possible in the 3D viewport instead of tweaking the animation in the graph editor
I've prepared a quick tutorial which explains how to use it for walk cycles
The character is taken from an instructional film that I did for Moyo productions in 2018
which can be found here:
I also did a presentation of the rig (which was still in version 2.79). You can have a look on it here:
